Changing over to setpoint generator operation
Setpoint generator operation can only be implemented without the motor
connected or with the motor mechanically de-coupled from the load.

1. The drive converter must be powered-down.
2. Set B60.X / P432 to 4 in the FP-WRS.
3. Set SWG.IRM / P872 to 1 in the FP-TRV.
4. Enter 0 % setpoint at SWG30.X (FP-TRV).
5. Enter 0 % frequency setpoint at SWG50.X (FP-TRV).
6. Power-up the drive converter, enable the inverter.
7. Enter the current setpoint, e.g. 30 % at SWG30.X.
8. Enter the frequency setpoint, e.g. 10 % at SWG50.X.
Re-establish the original settings (undo the changes) after you have completed this
operation (inverse sequence).
4.3.3
Checking the actual values
In order to be able to check the actual values, the closed-loop control must be
changed-over into setpoint generator operation (refer to Section 4.3.2). The current
actual values I
A
and I
B
can be tapped at the interface module -A132 (SU11),
terminals X2:3/4 and X2:5/6. In this case, in FP-TRC, the connector AUSW.IF must
be set to a logical 1, and in FP-TRV, the connector THEN27.IF must be set to a
logical 0. The currents I
A
and I
B
should be connected to an oscilloscope in the X-Y
display mode. Only a circle should be seen on the oscilloscope. At lower speeds,
the display may rotate in a counter-clockwise direction.
