3. The inverter keeps the motor at a standstill until the "motor holding brake opening time"
p1216 has ended.
The motor holding brake must be opened within time p1216.
4. The inverter accelerates the motor to the speed setpoint.
Function after an OFF1 or OFF3 command:
1. The inverter brakes the motor down to a standstill and switches it off using the OFF1 or
OFF3 command.
2. When braking, the inverter compares the speed setpoint and the actual speed with the
"standstill detection speed threshold" p1226:
– Speed setpoint < p1226: The "standstill detection monitoring time" p1227 starts
– Current speed < p1226: The "pulse cancellation deceleration time" p1228 starts
3. When the first of the two times (p1227 or p1228) has elapsed, the inverter issues the
command to close the brake.
4. After the "motor holding brake closing time" p1217, the inverter switches off the motor.
The motor holding brake must close within the time p1217.
Function after an OFF2 command
Figure 8-31
After an OFF2 command, the inverter issues the signal to immediately close the motor
holding brake, irrespective of the motor speed.
