Selecting the stop mode

Functionality
Both the inverter and the user have to respond to a wide range of situations and stop the
inverter if necessary. Thus operating requirements as well as inverter protective functions
(e.g. electrical or thermal overload), or rather man-machine protective functions, have to be
taken into account. Due to the different OFF functions (OFF1, OFF2, OFF3) the inverter can
flexibly respond to the mentioned requirements. Note that after an OFF2 / OFF3 command,
the inverter is in the state "ON inhibit". To switch the motor on again, you need a signal low
→ high of the ON command.

OFF1

The OFF1 command is closely coupled to the ON command. When the ON command is
withdrawn, OFF1 is directly activated. The inverter is braked by OFF1 with the ramp-down
time P1121. If the output frequency falls below the parameter value P2167 and if the time in
P2168 has expired, then the inverter pulses are cancelled.
