11.3 Switch-off responses
There are 4 switch-off responses depending on the error; the inverter remains blocked
in error status:
11.3.1 Output stage inhibit (immediate switch-off)
The unit can no longer decelerate the drive; the output stage goes to high resistance in
the event of a fault. The brake, if installed, is applied immediately.
11.3.2 Stop
The drive is decelerated with stop ramp t13. When the stop speed is reached, the brake
is applied immediately, if installed. The output stage then goes to high resistance.
11.3.3 Emergency stop
The drive is decelerated using emergency stop ramp t14. When the stop speed is
reached, the brake is applied immediately, if installed. The output stage then goes to
high resistance.
11.3.4 Standard stop
The drive is decelerated with the set standard ramp. When the stop speed is reached,
the brake is applied immediately, if installed. The output stage then goes to high
resistance.
11.4 Reset of error messages
An error message can be acknowledged:
• By switching the power off and on again
• Via the controller/PLC: Send "reset command"
WARNING
Eliminating the cause of the problem or performing a reset may result in the drive re-
starting automatically.
Severe or fatal injuries.
• Prevent the drive from starting up inadvertently, for example by activating STO.
