MP2040 Axis group (for axis-specific drive enable)
Format: %xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
(Spindle = bit 31)

MP2170 Waiting time between the switch-on of the drive and the
drive’s standby signal

Input: 0 to 20000
[Number of the PLC input or symbolic PLC operand]
-1: Function inactive
Bit 7 of MP2221.x enables you to deactivate the reduction of a drive's switch-
on time when it is switched on with PLC module 9161. If spindles with wye/
delta switchover but without evaluation of the status of the wye/delta
contactor are used, it may occur that the drive is switched on again before the
contactor has switched over to the appropriate mode. If this occurs, the
current controller sets the voltage to the maximum possible value. If the
contactor is then closed, this may lead to overcurrent, and as a result, to a
switch-off (e.g. due to error message 8B60) of the drive.
MP2221.x Bit 7 – Switch-on time of the drive
Input: 0: Reduction of the switch-on time is active
1: Reduction of the switch-on time is not active
Set Reset
W524 Open the control loop if drive enabling
via MP4132 is missing
Bit 0 = 0: Position control loop stays closed
Bit 0 = 1: Position control loop is opened
Bit 1 to bit 15: Non-functional
