3 Mechanical installation
Controller models below 160kW (both plastic and sheet metal structure) are installed
on a backplate in the control cabinet.
The following figure shows the installation details.

Figure 3-1 Backplate mounting

Note: Never fasten only the upper two screws, because the controller may fall and be dam-
aged with long-term running. So ensure that all the four screws are fastened.

Pay attention to the following points when designing the control cabinet:
● The temperature difference inside and outside the cabinet shall not be over 10°C
with temperature rise of the controller.
● A confined control cabinet must be configured with a fan (or other air cooling
device such as air conditioner) to ensure air circulation.
● The air from the fan must not blow directly to the drive unit because this easily
causes dust adhesion and further a fault on the drive unit.
● A vent must be available at the bottom of the control cabinet to form bottom-up
air flow for effective heat transfer.

‑17‑
Mechanical installation

● If the fan cannot meet the cooling requirements, install an air conditioner in the
cabinet or in the equipment room. Note that the temperature inside the cabinet
must not be too low. Otherwise, condensation may occur, causing short circuit of
components.
● For special environment where the temperature is high but cannot be reduced
effectively, de-rate the controller during use.

Notes
● Power input terminals R, S, T
■ The cable connection on the input side of the controller has no phase
sequence requirement.
■ The specification and installation method of external power cables must
comply with the local regulations and related IEC standards.
■ Refer to contents about peripheral device selection in the NICE3000new
Integrated Elevator Controller System Design and Selection Guide for proper
copper cables.
■ The filter must be installed close to the input terminal of the controller. The
cable between the filter and the input terminals must be shorter than 30 cm.
Ensure that the grounding terminals of the filter and the controller are

‑26‑
 Electrical Installation

connected together, and that both the filter and controller are installed on the
same conductive plane that are connected to main grounding of the cabinet.

Figure 4-4 Installation on the conductive plane

● DC bus terminals (+) and (-)

■ Terminals (+) and (-) of the DC bus have residual voltage after the controller is
switched off. Wait at least 10 minutes and ensure that the voltage is lower than
36 VDC before performing wiring. Failure to comply may result in electric shock.
■ When connecting external braking components for the controller of 75 kW and
above, never reverse (+) and (-). Failure to comply may result in damage to the
controller and even cause a fire.
■ The cable length of the braking unit must not exceed 10 m. Use twisted pair
wires or closely routed pair wires for parallel connection.
■ Do not connect the braking resistor directly to the DC bus. Otherwise, it may
damage the controller and even cause a fire.
● Terminals (+) and PB for braking resistor connection
■ These terminals are valid only for the models below 75 kW that have the built-
in braking unit.
■ Connect a braking resistor of the recommended model, and ensure that the
cable length is shorter than 5 m. Otherwise, it may damage the controller.
● Terminals U, V, W
■ The specification and installation method of external power cables must
comply with the local regulations and related IEC standards.

‑27‑
Electrical Installation

■ Refer to contents about peripheral device selection in the NICE3000new

Integrated Elevator Controller System Design and Selection Guide for proper
copper cables.
■ Do not connect a capacitor or surge protection device on the output side of the
controller. Otherwise, it may cause overheating or even damage to the
controller due to harmonics.

■ If the motor cable is too long, electrical resonance will be generated due to the
impact of distributed capacitance. This will damage the motor insulation or
generate higher leakage current, causing the controller to trip in overcurrent
protection. If the motor cable is greater than 100 m long, an AC output reactor
must be installed close to the controller.
■ Use the shielded cable as the output power cable connecting the motor. The
shield is connected to the grounding cable.

● Grounding terminal (PE)

■ The grounding terminal must be grounded reliably, and the resistance of the
grounding cable must be smaller than 10 Ω. Otherwise, the controller may
work abnormally or be damaged.
■ The grounding (PE) wire and neutral wire don’t share a terminal in the power
system.
■ Impedance of the PE conductor must be able to withstand the large short
circuit current that may arise when a fault occurs.
■ Select the size of the PE conductor according to the following table.

‑28‑
 Electrical Installation

Table 4–3 Size of PE conductor

Cross-sectional area of a phase conductor Min. cross-sectional area of protective
(S) conductor (Sp)
S ≤ 16 mm2 S
16mm2 < S ≤ 35mm2 16 mm2
S > 35 mm2 S/2

■ Use a yellow-green cable to connect the grounding conductor.

■ It is recommended that the controller be installed on the conductive metal
plane. Ensure that the entire conductive bottom of the controller is in good
contact with the metal plane. Install the filter and controller on the same plane
to ensure the desired filtering performance.
● Upstream protective device
■ Install proper devices on the power input side to offer electrical isolation and
protection against overcurrent and short circuit.
■ For selection of protective devices, consideration should be given to such
factors as the current capacity of power cables, the overload capacity
requirement of the system, and the short circuit capacity of the upstream
components.
● Cable shield requirements
Refer to contents about cable shield requirements in NICE3000new Integrated
Elevator Controller System Design and Selection Guide.

4.12 Installation of Shaft Switches

In elevator control, to implement accurate landing and safe running, the car position
needs to be identified based on shaft position signals. These shaft position signals
include the leveling switches, up/down slow-down switches, up/down limit switches,
and up/down final limit switches. These shaft position signals are directly transmitted
by the shaft cables to the MCB of the controller.
The following figure shows the arrangement of shaft position signals in the shaft.

 Electrical Installation

Figure 4-14 Arrangement of shaft position signals (unit: mm)

4.12.1Leveling Signals
Leveling signal devices, including the leveling switches and leveling plates, are
connected to the input terminals of the controller. They enable the car to land at each
floor accurately.
The leveling switches are installed on the top of the car. This controller supports the
installation of four leveling switches. The leveling plate is installed on the guide rail in
the shaft. One leveling plate needs to be installed on each floor. Ensure that leveling
plates at all floors are mounted with the same depth and verticality.

4.12.2Slow-down Switches
The slow-down switches are one of the key protective means of the elevator,
protecting against top-hitting and bottom-clashing even at maximum speed when the
elevator position is abnormal. This controller supports a maximum of three pairs of
slow-down switches. The slow-down switch 1, slow-down switch 2 and slow-down
switch 3 are installed from the two ends of the shaft to the middle floor one by one.
Generally, only one pair of slow-down switches is required for the low-speed elevator.
Two or three pairs of slow-down switches are required for the high-speed elevator.
The slow-down distance L indicates the distance from the slow-down switch to the
leveling plate at the terminal floor. The calculating formula is as follows:

L: Slow-down distance; V: Rated elevator speed (F0-04); F3-08: Special deceleration

rate.
The default value of F3-08 is 0.9 m/s2. The following table lists the slow-down
distances corresponding to different rated elevator speeds.

● V < 1 m/s: Compared with the values recommended in this table, the actual installation distances of slow-down switches
are allowed to have an error of ± 0.1 m.
● 1 m/s ≤ V ≤ 2 m/s: Compared with the values recommended in this table, the actual installation distances of slow-down
switches are allowed to have an error of ± 0.2 m.
● 2 m/s ≤ V ≤ 4 m/s: Compared with the values recommended in this table, the actual installation distances of slow-down
switches are allowed to have an error of ± 0.3 m.

‑57‑
Electrical Installation

Note
● The slow-down distances listed in the preceding table are calculated at the default
special deceleration rate (0.9 m/s2).
● A lower acceleration/deceleration rate or higher special deceleration rate does not
affect safety performance. However, a lower special deceleration rate may cause
safety hazards. If a rate change is required, calculate the slow-down distance
again according to the preceding formula.

4.12.3Limit Switches
The up limit switch and down limit switch protect the elevator against top-hitting and
bottom-clashing when the elevator does not stop at the leveling position of the
terminal floor.
● The up limit switch needs to be installed 30 mm to 50 mm away from the top
leveling position. The limit switch acts when the car continues to run upward for
the distance from the top leveling position.
● The down limit switch needs to be installed 30 mm to 50 mm away from the
bottom leveling position. The limit switch acts when the car continues to run
downward for the distance from the bottom leveling position.

4.12.4Final Limit Switches

The final limit switch is to protect the elevator against top-hitting and bottom-
clashing when the elevator does not stop completely upon triggering the up/down
limit switch.
● The up final limit switch is mounted above the up limit switch. It is usually 150 mm
away from the top leveling position.
● The down final limit switch is mounted below the down limit switch. It is usually
150 mm away from the bottom leveling position.

6.2.5 Motor Auto-tuning

Danger

To guarantee safe elevator running:

● Never start the elevator when the safety circuit is shorted. Failure to comply will
result in severe personal injuries or even death.
● Before emergency electrical operation, confirm that nobody is in the shaft. Failure
to comply may result in safety accidents.

Procedure
1. Set the switch to Emergency Electric Operation. Check that the X9 indicator on the
MCB becomes OFF and the elevator enters the EEO state.

‑78‑
 System Commissioning

2. Auto-tuning preparation
a. Check the equation and motor parameters: N=60 × f/P, where f is F1-04 (rated
frequency), N is F1-05 (rated speed), P is the number of pole pairs (number of
poles/2, mostly a positive integer).

b. Set F1-11 to 1 and select with-load auto-tuning. Press and the operating
panel displays "TUNE", indicating that the motor enters auto-tuning state.
3. Keep pressing the Up/Down button for the auto-tuning process. RUN contactor
closes and the motor has vibration noise due to excitation. After 3s to 5s, the brake
contactor closes and no fault is reported if the motor stops automatically with 2 or
3 rotations. With the encoder measured angle displayed by the LED for about 3s on
the MCB, the auto-tuning is completed successfully and the controller automati-
cally stops output. You can release the buttons now. If the fault code is displayed, it
shows the auto-tuning fails. Clear the fault first before performing auto-tuning
again.
4. Repeat step 3 (at least 3 times) and ensure that the encoder measured angles have
a difference within ±5°.
5. Finally, reset Emergency Electric Operation to Normal.

eration for EEO running test.
2. Press Up or Down button to check whether the running direction of the elevator is
consistent with that of the motor. If not, change F2-10 to 1 to reverse the running di-
rection of the elevator, and then repeat.

6.2.7 Car Top Commissioning

● During car top commissioning, ensure that car top inspection is enabled to
guarantee safety.
● The MCTC-CTB is high level active by default.

You need to set the NO/NC features of the CTB input signals in F5-25 and ensure that
they are consistent with those of the actual electrical parts (light curtain and door
open/close limit switches). The control by the CTB can be implemented only after the

‑80‑

d. Light curtain commissioning is completed.

2. Door operator controller commissioning

The door operator commissioning is used to check whether the input/output
control of the door operator controller is normal in the terminal control mode.
a. Check whether F7-05 is 0, the default value. If yes, it indicates that the door op-
erator allows door open (You may choose to skip this step).
b. Check whether the door open/close output of the door operator controller is
normal.
a. Short BM-B1 terminal of CTB CN4, and it indicates normal output control of
door operator controller 1 if door 1 opens.

b. Short BM-B2 terminal of CTB CN4, and it indicates normal output control of
door operator controller 1 if door 1 closes.

abnormal, refer to E51 solutions in Chapter 7.

‑84‑
 System Commissioning

Shaft auto-tuning enables the MCB to obtain the following information: floor height,
floor-to-floor height, and positions of final limit switches, limit switches, slow-down
switches, and leveling switches. These data provide a computation basis for
generating a running curve for the MCB.

Conditions
1. The elevator is in EEO state.
2. The elevator runs to a position below the leveling position of the bottom floor (at
least one leveling switch is disconnected from the leveling plate) and the down
slow-down switch 1 signal input to the MCB is active (for two landing floors only).

3. The system is not in the fault state. If there is a fault, press to reset the fault.

Note
Precautions for shaft auto-tuning of two-floor elevators:

When the elevator runs down to the bottom floor at inspection speed, the leveling switch
needs to be completely detached from the leveling plate.
Perform shaft auto-tuning again in following conditions:

● The positions of leveling plates or slow-down switches are adjusted on site.

● F0-04 (Rated speed), F6-00 (Top floor of the elevator), or F6-01 (Bottom floor of the
elevator) is modified.
● Each time the MCB or equipment is replaced, perform motor auto-tuning again.

6.2.9 Trial Run at Normal Speed

Perform trial run at normal speed to test whether the elevator runs properly in the
normal state.
Parameters in group F7 (set using the LED operating panel) are used in this test. F7-00
can be used as the car call button and set to any floor.

 System Commissioning

After the trial run is completed, power off and then get power back on. Then restore
parameters F7-00 to F7-07 to 0.

Note
● Parameters F7-00 to F7-08 can automatically change back to default values after
power-off and power-on.
● After shaft auto-tuning is completed, running at normal speed may fail as the full-
load/overload function is not commissioned. You can set F7-07 to 1 or set F-8 to 3
on the keypad to enable system overload before normal-speed running.

6.2.10HCB Commissioning (Optional)

The HCB address and the leveling plate are in a one-to-one relationship. It means that
the address is numbered according to the leveling plate numbered from bottom to
top on the same floor. If a leveling plate is installed on a non-service floor, an address
must be reserved for this floor.
Procedure
1. Install an HCB for each service floor. The non-service floors do not require the HCB.
2. Take MCTC-HCB-R600 as an example to set the HCB address. Short CN5 and adjust
the floor address through the up/down buttons. Press CN2 to add 1 and CN3 to sub-
tract 1.
A long press for 3s keeps increasing or decreasing the address until reaching the
required value: 1 to 56 (HCB address), 0/D2/D3/D4 (CCB address) and DH (HCB-B
without address display). Disconnect CN5 and the set address is automatically
saved after flashing for three times.

‑87‑
System Commissioning

Figure 6-5 MCTC-HCB-R600

Note
The HCB address is the same as the number of leveling plates on the same floor. For exam-
ple, the HCB address is set to N for the floor where the Nth leveling plate is located. If a lev-
eling plate is installed on a non-service floor, an address must be reserved for this floor.

3. After setting an address for each HCB, you can call the elevator by using the HCB to
start normal-speed running.

Note
● Set a unique address for each HCB. Otherwise, the HCB cannot be used.
● When the display board is used inside the car, its address must be set to 0.

Fault Symptom Solution

Change the motor wiring sequence and perform
auto-tuning again. The following figure shows how
to interchange motor phases.

Incorrect Note: Description of fault symptoms

motor Err20 and Err33 ① During no-load auto-tuning, if the motor wiring
wiring sequence is incorrect,
Err20 (E0-00) with fault subcode 3 (E0-01) will be
reported.
① During with-load auto-tuning, if the motor wiring
sequence is incorrect,
the synchronous motor will jitter abnormally
during auto-tuning, Err33 is reported, and auto-
tuning stops.
For the asynchronous motor, there is no prompt
during auto-tuning, but Err33 is reported during
inspection running.

Note
● When the preceding two problems occur, change the sequence of motor cables
connected to the controller.
● Adjustment principle of motor wiring sequence: interchange any two adjacent
motor cables once.

7.3 Handling of Common Door Control Problems

● In the door close state, the system sends a door open command but the door does
not open.

1. Check whether the door open limit signal is normally active.

2. Check whether there is door open output by viewing segment 1 of LED 1 in FA-
34.

3. If there is door open output (segment 1 ON), check whether cable connection
between the CTB and the door operator controller is correct and whether the
door operator controller works properly.

● The door does not close with a close command after reaching the open limit
position.

1. Check whether the light curtain signal is normally active.

2. Check whether there is door close output by viewing segment 2 of LED 1 in FA-
34.

3. If there is door close output (segment 2 ON), check whether cable connection
between the CTB and the door operator controller is correct and whether the
door operator controller works properly.

7.4 Adjustment to Abnormal Motor Startup

F2-00/01/03/04 are used to adjust the speed dynamic response characteristics of the
motor:

To achieve a faster system response, increase the proportional gain or reduce the
integral time. However, too large proportional gain or too small integral time may
lead to motor jitter due to oscillation.
Decreasing the proportional gain or increasing the integral time will slow the dynamic
response of the motor. However, too small proportional gain or too large integral
time may cause motor speed tracking abnormality, resulting in fault E33 or unstable
leveling at stop.
The default setting is proper for most large-power motors, and you need not modify
these parameters. These parameters need to be adjusted only for small-power
motors (such as P ≤ 5.5 kW) because they may have oscillation. To eliminate
oscillation, do as follows:
1. Decrease the proportional gain first (between 10 and 40) to ensure that the system
does not oscillate,
2. and then reduce the integral time (between 0.1 and 0.8) to ensure that the system
has quick response but small overshoot.
