SIMOVERT MASTERDRIVES
♦ For PRE-CHARGING (010), READY (011), RESTART-ON-THE-
1
FLY (013) 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♦ POWER-ON inhibit (008), until the command is withdrawn.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:
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)
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.
LOW signal in the RUN (014) condition.
♦ The ramp-function generator output is set to setpoint = 0.
LOW signal in the RUN (014) condition.
♦ The actual setpoint is "frozen at the ramp-function generator output".
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.
