Description
ESR: Configuration
Value Meaning
2 Extended retraction (function integrated in the drive)
Description
ESR: Off ramp
Value Meaning
0 OFF3 (default)
The drive is braked along the OFF3 down ramp by immediately entering n_set
= 0 (p1135: OFF3 ramp-down time).
1 OFF1
By immediately entering n_set = 0, the drive is braked along the ramp gener‐
ator down ramp (p1121: ramp-function generator ramp-down time).
Description
ESR: Timer
The parameter specifies the total time that elapses to reach the speed specified in
p0893 followed by constant velocity travel.
This is followed by an OFF1 or OFF3 ramp depending on the parameterization in p0891.
Description
ESR: Speed
The parameter specifies the speed (retraction speed) that is reached when initiating
retraction via an OFF3 ramp.
