Parameter
Explanation
p1213[0]
Automatic restart monitoring time
for restart
(factory setting: 60 s)
This parameter is only effective for the settings p1210 = 4, 6, 14, 16, 26.
With this monitoring function, you limit the time in which the inverter may attempt to
automatically switch-on the motor again.
The monitoring function starts when a fault is identified and ends with a successful start
attempt. If the motor has not successfully started after the monitoring time has expired,
fault F07320 is signaled.
Set the monitoring time longer than the sum of the following times:
+ p1212
+ Time that the inverter requires to start the motor on the fly.
+ Motor magnetizing time (p0346)
+ 1 second
You deactivate the monitoring function with p1213 = 0.
p1213[1]
Automatic restart monitoring time
to reset the fault counter
(factory setting: 0 s)
This parameter is only effective for the settings p1210 = 4, 6, 14, 16, 26.
Using this monitoring time, you prevent that faults, which continually occur within a
certain time period, are automatically acknowledged each time.
The monitoring function starts with a successful start attempt and ends after the moni-
toring time has expired.
If, during the monitoring time p1213[1], the inverter made more successful starting at-
tempts than defined in p1211, the inverter interrupts the automatic restart function and
signals fault F07320. To switch on the motor again you must acknowledge the fault and
switch on the inverter (ON/OFFS1 = 1).
Additional information is provided in the parameter list of the List Manual.
Advanced settings
If you with to suppress the automatic restart function for certain faults, then you must enter
the appropriate fault numbers in p1206[0 … 9].
Example: p1206[0] = 07331 ⇒ No restart for fault F07331.
Suppressing the automatic restart only functions for the setting p1210 = 6, 16 or 26.
WARNING
Danger to life if an OFF command has no effect.
When the inverter is only controlled via the fieldbus interface, the motor restarts with the
setting p1210 = 6, 16, 26 – even if the communication link is currently interrupted. When
communication is interrupted, the control system cannot switch off the motor.
• Enter the fault number of the communication error in parameter p1206.
Example:
Fault number F01910 means: Communication via PROFIBUS failed.
Set p1206[n] = 1910 (n = 0 … 9).
