For PRE-CHARGING (010), READY (011), RESTART-ON-THE-
FLY (013)
1
or MOT-ID STANDSTILL (018), the inverter pulses are
inhibited, and the main/bypass contactor, if used, is opened.
♦
If the drive operates as slave drive, when an OFF3 command is
issued, it automatically switches-over to the master drive.
♦
POWER-ON inhibit (008), until the command is withdrawn.
The
OFF3
command is simultaneously effective from three sources
(P558, P559 and P560)!
Priority of the
OFF
commands:
OFF2
>
OFF3
>
OFF1
Bit 3: Inverter enable command (H "inverter enable")/(L "inverter inhibit")
HIGH signal, READY (011) and the de-energization time (P603) has
expired since the last time that the drive was shutdown.
♦
RUN (014)
The inverter pulses are enabled and the setpoint is approached via
the ramp-function generator.
LOW signal
♦
For RESTART-ON-THE-FLY (013)
1
, RUN (014):
The drive changes over into the READY (011), condition, and the
inverter pulses are inhibited.
♦
If OFF1 is active (015), the inverter pulses are inhibited, the
main/bypass contactor, if used, is opened, and the drive goes into
the POWER-ON INHIBIT (008) condition.
♦
If OFF3 is active (016 / fast stop), the inverter inhibit command is
ignored, fast stop is continued and, after shutdown (P800, P801),
the inverter pulses are inhibited.
Bit 4: Ramp-function generator inhibit command (L "RFG inhibit")
LOW signal in the RUN (014) condition.
♦
The ramp-function generator output is set to setpoint = 0.
Bit 5: Ramp-function generator hold command (L "RFG hold")
LOW signal in the RUN (014) condition.
♦
The actual setpoint is "frozen at the ramp-function generator output".
Bit 6: Setpoint enable command (H "setpoint enable")
HIGH signal and the de-energization time have expired (P602).
♦
The setpoint at the ramp-function generator input is enabled.

The "Restart-on-the-fly" function has not been provided.
