Example: Saving the offset after power off
Note: If the mains is switched off, the drive comes to a stop by itself.
When the mains is reconnected and a new start signal, the
drive is accelerated from 0 Hz.
If the STL contact remains active during power off, the drive
does not start. The drive does not accelerate to the base value
until after a new STL edge.
If an automatic restart required after power return, the auto
start function must be activated in the parameter 72-STRT
(see Chapter 6).
Key:
➀ Offset is saved with power off
(only possible with 04-FSSEL = 19/20).
➁ Offset is lost with power off
(with 04-FSSEL = 17/18/21/22).
