Lenze i550 - Switch-Off

12.6.5.1 Switch-o
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 deacvated and the device status of the i700 servo inver-
ter is "Operaon enabled", this command sets the pulse inhibit again.
•
If automac brake operaon is acvated, the parameterised brake closing me
(0x2820:002 (P712.02)) is observed: The system waits unl the brake is applied before the
pulse inhibit is set. In velocity mode, the brake closing me is not observed.
•
The motor becomes torqueless.
•
The device state "Switched on" or "Operaon enabled" changes back to the "Ready to
switch on" state.
DANGER!
Uncontrolled movement
If the motor becomes torqueless, a load that is connected to motors without a holding brake
may cause uncontrolled movements!
▶
Without a load, the motor will coast.
