Ch.1
1.11.2.1 Power Loss Ridethru (Pwrloss Ridethru)
When the DC link voltage reaches the starting threshold, the function gets active.
The DC link setpoint is set with a value higher than 12% as compared to the Undervoltage threshold.
The PI regulator controls a negative torque current (recovery) in order to keep the DC link at a constant level.
When the Mains voltage is restored, the system allows a delay on the line speed with the set acceleration time.

1.11.2.2 Power Loss Stop (Pwrloss Stop)
Through the PSL mains st src source, the function allows the selection of the command signal, which can state
the Mains recovery (for example via a programmed digital input). The aim is to restart the motor before it reaches
a Speed 0. In the configurations it is possible to set the gain of the internal PI regulator, the DC link reference
threshold with PLS Vdc ref, the torque current limit with PLS curr lim and with PLS timeout a maximum period
after which no automatic restart is possible.
