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 or 16.
In the case of communication via the field bus interface, the motor restarts with the setting
p1210 = 6 even if the communication link is interrupted. This means that the motor cannot
be stopped via the open-loop control. To avoid this dangerous situation, you must enter the
fault code of the communications error in parameter p1206.
Example: A communication failure via PROFIBUS is signaled using fault code F01910. You
should therefore set p1206[n] = 1910 (n = 0 ... 9).

Explanation
Automatic restart monitoring time
for restart (factory setting: 60 s)
This parameter is only effective for the settings p1210 = 4, 6, 14, 16.
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.
Automatic restart monitoring time
to reset the fault counter (factory setting: 7200 s)
This parameter is only effective for the settings p1210 = 4, 6, 14, 16.
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
monitoring time has expired.
If the inverter has made more than (p1211 + 1) successful start attempts within
monitoring time p1213[1], the inverter cancels the automatic restart function and signals
fault F07320. In order to switch on the motor again, you must acknowledge the fault and
issue a new ON command.
