Adjusting the Inversion Parameter

Adjustment Procedure

Determine the inversion parameter as follows:

Select Debug mode.
Select DIRDRIVE loop control disabled mode.
Acknowledge faults: Acq. button in the Faults zone.
Enter details in succession into the PARAM field in accordance with the following table:
- +100 mV (positive analog output),
- -100 mV (negative analog output).

Action to be Taken

The following table shows the action to be taken, according to the change in position and value. This depends on the voltage (positive or negative) which has been defined for the analog output:

Analog output	Position	Measurement	Action to be taken
Positive	Increase	Increase	None (connection OK)
Positive	Increase	Decrease	Invert the measurement
Positive	Decrease	Decrease	Invert the setpoint
Positive	Decrease	Increase	Invert the setpoint and the measurement
Negative	Decrease	Decrease	None (connection OK)
Negative	Decrease	Increase	Invert the measurement
Negative	Increase	Increase	Invert the setpoint
Negative	Increase	Decrease	Invert the setpoint and the measurement

NOTE: If the offset is greater than 100 mV, you must first adjust it before proceeding.
