FUNCTION / Power loss ctrl

Menu accessible with Access Level = FULL.
The Function allows to control a power loss or a break of the Mains voltage.
In the configurations, via the
I01.00 - PL function sel
parameter, it is possible to set
several methods to control a possible power loss:
[0] Off
Function is not active
[1] PL stop
It is a controlled stop during which, through the energy recovered from the
load, the motor is constantly controlled.
The DC link voltage is controlled in order to be kept closed to the
I03.12 - PLS Vdc ref
reference (internal value, it is usually closed to the
Overvoltage voltage).
In this case the aim is to try to perform a controlled stop of the machine.
The control variable is the torque current limit.
[2] PL ridethru
With this setting it is possible to let the motor shaft rotate as long as
possible during some Mains holes.
The DC link voltage is controlled in order to be kept slightly higher than
the Undervoltage threshold, thus minimizing the losses. In this case the
Mains hole is considered to be temporary and a crossing attempt is
performed.
The control variable is an additional reference for the torque current
(negative).
A signal,
I01.21 - PL next fact
, supplies the ratio between the motor speed and the speed
reference. By connecting it to the speed ratio of the slave drive, it is possible to obtain the
line synchronism.
