When the controller is disabled, the speed setpoint will be set to zero. When the actual speed is about
zero, the holding brake is activated. The
stop delay takes effect as of this point of time. During this
time, the drive will be kept in its current position until the holding brake has developed its full holding
torque. When the delay period is over, the controller is disabled. In both cases, the mechanical wear of
the holding brake is reduced.

10 V. They have
a resolution of 12 bits. These inputs can be used flexibly to assign speed and torque setpoints.
If you select Parameters/IOs/Analog inputs or click the "…" button in the setpoint selector menu
