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.
Function diagrams 180 and 190 refer to further function diagrams in the
Compendium.
Positive edge change from L to H (L → H) in the READY TO POWER-
UP condition (009).
♦ PRECHARGING (010)
Main contactor (option)/bypass contactor, if available, are switched-
in (closed).
The DC link is pre-charged.
♦ 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
♦ GROUND FAULT TEST (012), only when the ground fault test has
been selected (P375).
♦ RESTART ON THE FLY (013), if restart on the fly (control word bit
23 via P583) has been enabled.
♦ RUN (014).
LOW signal and P100 = 3, 4 (closed-loop frequency/speed control)
♦ OFF1 (015), if the drive is in a status where the inverter is enabled.
• For P100 = 3, 4 and slave drive, the system waits until the
higher-level open-loop/closed-loop control shuts down the drive.
• For P100 = 3, 4 and master drive, 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If the OFF1 command is withdrawn again when the drive is ramping-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.
