Implementation of the Stop Category 1

Bringing the motor to a standstill by interrupting the mains supply and using controlled
electronic braking (STOPMODE & ACTFAULT parameters set to 1). The 24 V supply
for the SERVOSTAR must remain constant.
The drive is braked in a controlled manner during the stopping (disabling) procedure. If
the speed VEL0 (see sequence diagram in chapter 6.3) is undershot, the holding brake is
applied and the output stage is disabled.
As soon as two separate time periods (set at the time relay) have elapsed, the mains sup-
ply and the holding brake are electrically isolated.
Should an internal SERVOSTAR 300 fault occur, the motor is forced to a standstill
once K20 drops out.
