 General

1. General The AC motor control KEB COMBIVERT F5-M serves exclusively for
stepless speed control and regulation of three-phase induction motors.
The operation of other loads is not permitted and can lead to the
destruction of the unit. With a few additional adjustments, the F5-Multi
control is ready for the basic applications of speed control or torque
control of closed loop AC induction vector motors.

Upon delivery of the system, the controller is configured with typical three-
phase induction motor data. However for proper operation, it is always
GB necessary to enter the actual motor data from the name plate or
manufacturer's specification sheet of the motor. With this minimum
information the COMBIVERT F5-M can control motors made from many
manufacturers.

KEB COMBIVERT F5-Multi has a very extensive and flexible programming

structure. To make the operation and start-up simpler for the user, a
special operator level (CP. Parameters) was created in which the most
common parameters are found. If the parameters predefined by KEB are
not sufficient for your application, an in depth application manual is
available for purchase. Please contact your local KEB sales office for
more information.

2.3.3 X3B Incremental ONLY when the inverter is switched off and the voltage
Encoder Input supply is disconnected may the feedback connectors be
removed or connected!

The second incremental encoder input serves for synchronous (i.e.

electronic gearing) or positioning applications. Synchronized master-
follower applications, this input would be connected to a master axis and
the inverter would follow at the rate commanded by the master. Positioning
applications, this input would serve to close the position loop by using a
secondary encoder to correct real-time positioning errors on the fly. In
order to use this input, you must be in APPLICATION mode. Please
consult the F5M/S application manual for use and adjustment.

2.4 Digital Operator As an accessory for displaying and editing "CP" parameter values, a "digital
operator" is necessary. To remotely mount the digital operator, a operator
remote cable is required (option: cable 00.F5.0C0-1xxx).
To prevent malfunctions, the inverter must be brought into nOP status
(remove signal from control release terminal 16) before connecting /
disconnecting the operator. When starting the inverter without an
operator, it is started with the last stored values in memory.

 Operation of the Unit

3. Operation of the Unit

3.1 Keypad When switching on the KEB COMBIVERT F5, the value of parameter
CP.1 appears in the operator display. (See "Drive Mode" to switch the
keypad function)

The function key (FUNC)

changes between the
parameter value and
parameter number.

With UP and DOWN , the

value of the parameter
number is increased /
decreased.

Generally; when a value is changed, parameter values are immediately

accepted and stored nonvolatile. However, with some parameters it is
not useful that the adjusted value is accepted immediately. In these
cases (CP.28, CP.32, CP.33, CP.34) the adjusted value is accepted and
stored nonvolatile by pressing ENTER.

If a drive fault occurs during operation, the current display changes to the
drive fault message. The drive fault message in the display is cleared by
pressing ENTER.

Error

Pressing ENTER only clears the fault message in the display.

In the inverter status display (CP. 3), the fault is still displayed
until the inverter has been reset. In order to reset the fault itself
the cause must be identified and removed, then a reset signal
applied to terminal X2A.17 or a power-on reset (i.e. cycle
supply voltage off; wait for display to clear or go blank, than
turn power on) must occur.

2)
Based on power stage

Based on motor data (see section 3.7, "Motor Data")

Due to measuring accuracies, computation resolution and influences resulting from

temperature change, tolerances in the current and torque values must be taken into
consideration when they are used to trigger events or limit operation. These values are also
dependent on the normal manufacturing tolerances of the motor. Thus larger tolerances are
possible due to variations in one motor to the next.
