1 General

1.1 Basic Description

The VARIODYN 35, VARIODYN 45 and VARIODYN 70 are members of the SCHINDLER VARIODYN
frequency converter series. The VARIODYN 35/45/70 supply asynchronous motors with variable frequency
and variable three-phase voltage. They associate the positive properties of the three-phase AC drive
(suitability for heavy duty, freedom from maintenance) with those of the direct-current drive (high regulation
dynamics, low energy consumption), thus having a positive effect on the following properties during elevator
operation:
D Landing - extremely accurate
D Ride comfort - excellent with minimum floor-to-floor time
D Energy consumption - very low.
The following features are also to be mentioned:
D Low mains feedback
D Low starting current/rated current ratio at mains
D Application of the latest integrated power module technology with IGBTs
D Controlled torque at zero speed to compensate load
D Short-circuit-proof power electronics
D High control quality by a digital field-oriented vector regulation
D Diagnostic possibilities (SMLCD, CADI)
D Preconfigured drive requiring no adjustments in field.
The VARIODYN 35/45/70 frequency converters are SCHINDLER in-house developments. They are
arranged, together with the MICONIC SX modular control, in a single controller cabinet.
Its typical application is in the speed range of VKN+1.0 m/s ... 1.75 m/s. Drive units must be taken from the
SCHINDLER VARIODYN-motor-series (VM-motors) and the SCHINDLER worm-gear-series.
The cabinet hardware and external interfaces of the control part are identical with the MICONIC SX with the
exeption that for all VARIODYN drives the control pcb PGO1683 is used.
The control software used is the TX software which is adapted to the PGO1683. All functions of the SX and
TX-software are supported.1) The TX version of CADI must be used.

5 Product Description

5.1 Function Overview

Frequency Converter
VARIODYN 35/45/70 frequency converters supply variable frequency and variable voltage to asynchronous
motors.
The PVF receives the speed reference value via an RS 232 interface from the processor print PGO1683,
and the actual value from an increment pulse generator (speed tachometer). This is an IG 2000 for geared
motors.
The signal representing the difference between the reference value and actual value is processed in the
speed regulator.
Furthermore, for current regulation, the motor currents of two phases are measured. From these input
quantities, the current reference values are calculated in the speed regulator by means of field-oriented vector
regulation and are transmitted to a two-position regulator (bang-bang regulator). This then generates the
corresponding control signals for the power transistors, so that the motor currents follow predetermined
current reference values as closely as possible. The signals are first fed to earth short cut measuring print
UKE and then to the driver stage incorporated in the SKiiP1) module, which control the IGBTs.

Recuperation Into the Mains

There is no recuperation of energy into the supply mains. Brake energy is converted into heat by means of
a resistor.

Load Measuring
The load measuring is made with contacts on the car platform or with DMS (device with strain gauge and relay
contacts), which generate the minimal -, maximal - and overload-information. Today this information is only
used for control function on the PGO processor print.
Load measuring with LDMS-VCOM is not provided with MICONIC SX.

5.2 Regulating Unit (Power Electronics)

Functional Blocks (as shown in Fig. 4)

The regulating unit [PE] converts a three-phase supply with constant voltage and frequency into a
three-phase supply with variable voltage and frequency.

Input Circuit
The input circuit consists of the following elements: mains filter (FENA), charging resistor (WGR), charging
contactor (SGRW) and main’s contactor (SGR). These switch the three-phase supply to the converter and
damp the high-frequency interference generated in the appliance.

Rectifier
The uncontrolled rectifier (consisting of diodes) has the task of rectifying the three-phase main’s voltage and
using this to supply an intermediate direct-voltage circuit.

Intermediate Direct-Voltage Circuit

The intermediate direct-voltage circuit smoothes the direct voltage (CKZ) and damps the mains-current
harmonics (LKZ).
The DCLI print is balancing the voltages across the series capacitors in the DC-link capacitor bank. Moreover
the DCLI print contains a high-impedance interface for the quasi potential free DC-link measurement on the
UKE print.

Braking Chopper
The braking chopper limits the intermediate-circuit voltage when the elevator motor is operating as a
generator and at the same time converts the energy occurring into heat by means of a forced-ventilated brake
resistor (WBR).
No energy is returned into the mains.
The IGBT and the correspondent free-wheeling diode for the braking chopper with the respective driver and
DC-link voltage regulator is integrated in the SKiiP-module.
The braking-chopper device records the intermediate-circuit voltage and regulates it by controlling a
transistor according to the 2-point control method.

Inverter (WR)
any way nor used for manufacturing nor communicated
This design and information is our intellectual property.
It must without our written consent neither be copied in

The inverter (WR) breaks down the smoothed direct voltage into a three-phase system with variable voltage
and frequency by suitable switching of the WR-IGBTs (Insulated Gate Bipolar Transistor) which are designed
as a three-phase bridge. The control signals, which are generated by the speed processor (PVF), are
galvanically separated and amplified by the driver stages (within the SKiiP-module). The WR protective
functions (overcurrent, overvoltage, excess temperature, short-circuits) are monitored and processed
directly or indirectly by the PVF.

Output Circuit
to third parties.

Two current sensors record the actual value of the asynchronous motor current (MI-U, MI-W) for the
regulation. The output contactor (SF) separates the motor from the inverter after each trip according to the
standards.

Regulation
The speed processor print PVF receives the speed reference value from the processor print PGO1683 via
an RS 232 interface. It receives the actual speed value from an increment pulse generator (speed
tachometer), which is an IG 2000 for geared. The difference signal of the reference value and the actual value
is processed in the speed regulator.
The flux reference value is formed from the motor parameters and the intermediate-circuit voltage. The
difference signal of the flux reference value and calculated actual flux value is processed in the flux regulator.
A current reference value is calculated by means of the output quantities of the flux regulator and the speed
regulator and is transmitted to a two-position regulator. The two-position regulator finally generates the
corresponding control signals for the six power transistors (IGBTs) so that the motor current exactly follows
the predetermined reference value.

Control and Monitoring

The speed processor print PVF controls the input contactors (SGR, SGRW) and the fan. Moreover, event
and fault handling are carried out and status messages indicated.

Auxiliary Devices
The auxiliary devices combine the voltage supplies for printed circuit boards, contactors and fans. The speed
processor PVF is fed by a power supply (UKE). In the UKE also additional protection functions are
implemented (earth short cut, inverter inhibit, CKZ asymmetry, etc.).

5.3 Matching Transformer

Application
The matching transformer (TA) is an option and is applied if the mains voltage, including tolerances, is outside
the range 360 V...440 V (400 V "10 %).

Operation outside specified mains voltage range
D Safety operation is not guaranteed if the input voltage exceeds 480 V, for more than a second.
D Operating between 440 V and 460 V may cause overheating and related side effects, that will reduce
the life expectancy of the components.
D System shuts down when the voltage drops below 360 V, but recovers when it returns to normal.
Operation outside specified ambient temperature range
D Operation up to 50° C ambient temperature on a commission basis.
