Switch-off
This command serves to change the "Switch-on inhibited" device state to the "Ready to switch on" device state.
If the pulse inhibit has already been deactivated and the device status of the inverter is "Operation enabled", this command sets the pulse inhibit again.
–
If automatic brake operation is activated, the parameterized Brake closing time (0x2820:002 (P712.02)) is observed: The system waits until the brake is applied before the pulse inhibit is set. In the CiA 402 "CiA: Velocity mode”, the Brake closing time is not observed.
–
The motor has no torque.
–
The device state "Switched on" or "Operation enabled" changes back to the "Ready to switch on" state.
DANGER!Uncontrolled motor movements by pulse inhibit.
If the motor has no torque, a load that is connected to motors without a holding brake may cause uncontrolled movements! Without a load, the motor will coast.
Possible consequences: Death or severe injuries
▶
Only operate the inverter under permissible load conditions.
