During current adjustment, proceed as follows:
 Switch the control on.
 Do not acknowledge the Power Interrupted message. In the Programming
and Editing mode of operation, use the MOD key to enter the code number
688379. The oscilloscope is started.
 Press the I CONTROL soft key.
 In the Manual Operation mode of operation, acknowledge the Power
Interrupted message and switch the control voltage on.
 Use the SELECT AXIS soft key in the oscilloscope to select the axis to be
adjusted.
 With the P/I FACTOR soft key, select the I factor and set MP2430.x = 0.
 With the P/I FACTOR soft key, select the P factor.
 As a starting value for the P factor first enter the value 0, select the step
increment SLOW, and press the ↑ soft key about 5 to 10 times.
 Press the START STEP soft key.
This sends multiple step functions to the current controller and measures
the step responses. The height and length of the steps are automatically
calculated by the control.
Applying a voltage causes a brief humming noise.
 With the ↑ soft key, increase/decrease the P factor (MP2420.x) step by step
just enough so that no overshoot is visible.
 Save this value with the STORE MP2420.x soft key.
 With the P/I FACTOR soft key, select the I factor.
 As a starting value for the I factor first enter the value 0, select the step
increment SLOW, and press the ↑ soft key about 5 to 10 times.
 With the ↑ soft key, increase/decrease the I factor (MP2430.x) step by step
just enough so that no overshoot is visible.
 Save this value with the STORE MP2430.x soft key.
 Press the END key to exit the Commission Current Controller mode.
The control carries out a reset.
Danger
If the brakes are not active, the motor can move somewhat (in the direction
of a preferred position)!
The error message Standstill monitoring <axis> might be displayed. It
can be deleted.
Note
For linear and torque motors, adjust the P and I component of the current
controller so that no overshoots are visible in the step response. This
reduces motor noise.
