11.15.2 Restart protecon
The integrated restart protecon is to prevent a restart in the lower frequency range if the
mains voltage was only interrupted briey (mains recovery before the motor stands sll).
•
In the default seng 0x2D66:008 (P721.08) = 0 Hz, the restart protecon is deacvated.
•
In order to acvate the restart protecon, set the restart threshold in [Hz] in 0x2D66:008
(P721.08) below which no automac start shall take place aer mains recovery.
•
If, in case of mains recovery, the output frequency is below the restart threshold, the
restart protecon gets acve:
•
If the current DC-bus voltage is lower than the voltage setpoint 0x2D66:005 (P721.05),
the motor is connued to be decelerated (unl frequency 0 Hz).
•
If the current DC-bus voltage is higher than the voltage setpoint 0x2D66:005 (P721.05),
the motor is accelerated in a controlled way unl the output frequency exceeds the
restart threshold.
•
If, in case of mains recovery, the output frequency is above the restart threshold, the
motor is accelerated again to the frequency setpoint. 4Fast mains recovery ^ 316
Diagnosc parameters:
•
An acve restart protecon is displayed via the status bit 0 in 0x2D66:009 (P721.09) if the
mains failure control is not acve.
Terminang the acve restart protecon
If, aer mains recovery, the restart protecon is acve, it can be terminated by the following
acons:
•
Error reset via the trigger set in 0x2631:004 (P400.04).
•
Short-me inverter disable via the trigger set in 0x2631:001 (P400.01).
•
Restart via the trigger set in 0x2631:002 (P400.02).
11.15.3 Fast mains recovery
A fast mains recovery is caused by a short interrupon at the energy supply company (for
instance due to a thunderstorm) and by faulty components in the supply cables (for instance
slip rings).
The fast mains recovery causes a restart of the motor
•
if the restart protecon is deacvated (0x2D66:008 (P721.08) = 0 Hz, default seng)
or
•
the restart protecon does not get acve (output frequency > 0x2D66:008 (P721.08)).
If this behaviour is not desired, you can decelerate the restart by seng a switch-o me in
0x2D66:007 (P721.07) or prevent it in connecon with the restart protecon. 4Restart pro-
