Operating Manual
Setting range: 1 ... 10
p1211
Automatic restart starting attempts
Factory setting: 3
Setting for the automatic restart attempts of the automatic restart function.
If the active faults could not be acknowledged within the current waiting time (derived from p1212 and
p1213) or if new faults are present, this number is decremented internally.
Automatic restart is aborted as soon as all starting attempts have been made.
The internal counter is set to p1211, however, as soon as 4 seconds of waiting time have elapsed since
the last successful starting attempt.
This parameter setting is active when p1210 = 2 ... 6.
Setting range: 0.5 ... 10.0 s
p1212
Automatic restart waiting time first starting
attempt
Factory setting: 1.0 s
Setting for the waiting time after the first starting attempt.
Another startup is not possible until the waiting time has elapsed.
This parameter setting is active when p1210 = 2 ... 6.
Setting range: 0.0 ... 10.0 s
p1213
Automatic restart waiting time increment
Factory setting: 0.0 s
Setting for the waiting time increment of the automatic restart function.
The active waiting time is determined with p1212 and p1213. With every unsuccessful starting attempt,
the time is increased by p1213 (exception: p1213 is not taken into account with the first starting attempt).
This parameter setting is active when p1210 = 2 ... 6.
Settings
To prevent the motor from switching into phase opposition when the drive is being
restarted, there is a delay while the motor demagnetizes (t = 2.3 x motor
magnetization time constant). Once this time has elapsed, the inverter is enabled
and the motor is supplied with power.
