Tab. 7-23:
Parameter list of pressure sensor failure detection
The pressure sensor failure protection can be activated via bit0 of F4.00. It
works in three different phases:
●
Motor runs in negative direction of rotation
Once motor runs in negative direction, this function will check if the mo‐
tor speed is consistently lower than [F4.06] for [F4.07] seconds and sig‐
nal a failure for this.
Fig. 7-36:
Motor reverse speed limit
●
Motor runs in positive direction
Once motor runs in positive direction with the speed higher than [F4.08],
this function will check if the pressure feedback is consistently lower
than 0.5 bar for [F4.09] seconds and signal a failure for this.
