Device information
7.1.1
Fault memory
The inverter stores the error message in fault memory
P080
. The inverter does not save
a new fault until the error message has been acknowledged. The local operating panel
shows the most recent error. Whenever double faults occur, the value stored in
P080
does not correspond to the value displayed on the operating panel. This is an example
of what happens with
F07 DC link overvoltage
followed by
F34 Ramp timeout
.
The inverter stores the following information when a malfunction occurs:
• Error occurred
• Status of the digital inputs / digital outputs
• Operating state of the inverter
• Inverter state
• Heat sink temperature
• Speed
• Output current
• Active current
• Unit utilization
• DC link voltage
7.1.2
Switch-off responses
There are 3 switch-off responses depending on the fault:
Immediate stop/malfunction (immediate switch-off with locking)
This fault response causes immediate locking of the output stage with simultaneous
control of the brake output so that an existing brake is applied. The "fault message" is
set and the "ready message" is revoked.
This status can only be exited by an explicit fault reset.
Rapid stop/malfunction (stop with locking)
This fault response causes a stop at the set stop ramp (
P136
/
P146
). This fault stop is
subject to time monitoring. If the drive does not reach the start / stop speed within a
specified time period, the unit goes to the fault state, the output stage is inhibited and an
existing brake is applied. The fault message
F34 Ramp timeout
is generated. The orig-
inal fault message is overwritten. If the drive reaches the start/stop speed, the unit goes
to the fault state, the brake is applied and the output stage is inhibited. The "fault mes-
sage" is set and the "ready message" is revoked.
This status can only be exited by an explicit fault reset.
