 How to optimise the current controller in the test mode:

1. If the controller is enabled, inhibit the controller, e. g. with the device command

C00002

= "41: Inhibit controller".

2. Set a fixed switching frequency using C00018

. Observe the above mentioned

recommendations.

3. Activate one of the two following optimisation modes for the current controller:

• C00398

= "3: Current controller optimisation mode":

After controller enable, the motor is supplied with current as long as the controller is

enabled.

• From software version V7.0:

C00398

= "4: Current controller optimisation mode pulse":

The motor is supplied with voltage for 50 ms after controller enable. Due to this time

limit, the load of the machine is reduced. Afterwards, the controller is inhibited

automatically.

4. Select the effective value of the current setpoint step change under C00022

.

• The peak value of the measurable motor current will be 1.41 times higher.

5. Enable the controller for a short time and measure the step response of the motor current

in the motor phases using the oscilloscope and clamp-on ammeters or record the field-

oriented direct-axis current using the Oscilloscope

function in »Engineer«. ( 579)

• Variable of the motor control to be recorded:

Current.dnActualDirectCurrent (field-oriented direct-axis current)
