SIMOVERT MASTERDRIVES
The operating statuses can be read in visualization parameter r001:
e.g. READY TO POWER-UP: r001 = 009
The function sequences are described in the sequence in which they
are actually realized.
An overview of the control word can be found in function diagrams 180
and 190.
Positive edge change from L to H (L → H) in the READY TO POWER-
UP condition (009).
♦ PRECHARGING (010)
The main contactor (option), if present, is closed.
Precharging is carried out. After precharging, the bypass contactor,
if present, is closed.
♦ READY (011)
If the drive was last powered-down with "OFF2", the next condition
is only selected after the de-energization time (P603) has expired
since the last shutdown.
♦ RUN (014).
LOW signal
♦ OFF1 (015), if the drive is in a status where the inverter is enabled.
• For P290 = 0 and slave drive, the system waits until the higher-
level open-loop/closed-loop control shuts down the drive.
• For P290 = 0 and master drive as well as for P290 = 1 (v/f
characteristic), the setpoint at the ramp-function generator input
is inhibited (setpoint = 0), so that the drive decelerates along the
parameterized down ramp (P464) to the OFF shutdown
frequency (P800).
After the OFF delay time (P801) has expired, the inverter pulses are
inhibited, and the main contactor (option/bypass contactor), if
available, are opened.
If the OFF1 command is withdrawn again when the drive is ramping-
down, (e.g. as the result of an ON command), ramp-down is
interrupted, and the drive goes back into the RUN (014) condition.
♦ For PRECHARGING (010), READY (011), RESTART-ON-THE-FLY
1
(013) or MOT-ID-STANDSTILL (018), the inverter pulses are
inhibited, and the main contactor (option)/bypass contactor, if
available, is opened.
♦ POWER-UP INHIBIT (008)
♦ READY-TO-POWER-UP (009), if "OFF2" or "OFF3" are not present.

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