Please note:
Note
For analog axes, you must adjust the servo amplifier before you optimize
the position controller.
Procedure:
7 7 7 7
Disconnect the nominal-value connection between the servo amplifier and
the logic unit.
7 7 7 7
Short-circuit the nominal value input on the servo amplifier.
The input must have a 0 V voltage.
7 7 7 7
Activate control enabling at the servo amplifier.
7 7 7 7
Connect the supply voltage to the servo amplifier.
7 7 7 7
Perform a coarse offset adjustment:
• If the axis moves in spite of the short-circuited nominal value input, you
must adjust the offset potentiometer until the axis stops moving.
7 7 7 7
Remove the jumper at the nominal value input and establish a nominal-value
connection to the logic unit.
