Speed limiting
If you need a direction-dependent speed limiting, you can define speed limits for each
direction.
Torque limiting
You can specify the torque limiting as an absolute value. The limiting acts both when
motoring as well as generating.
Danger to life due to uncontrolled movement of the drive as a result of incorrect parameter
assignment
Incorrect parameterization of the torque limiting can result in uncontrolled movement of the
drives if there is no counter-torque, and cause death or serious injury.
Ensure the correct parameterization.
Zero speed detection
Specify the speed threshold for the zero speed detection of the motor. For braking with
OFF1 or OFF3, the zero speed is detected when this threshold is fallen below.
Speed threshold values for message
Also specify the speed threshold values for the following messages of the drive status word:
● "Speed threshold 1" (p2141)
If the speed exceeds the threshold value, bit 10 is set as feedback in ZSW 1.
● "Speed threshold 4" (p2163)
As long as the speed deviation lies within the tolerance range, bit 8 in ZSW1 is set as
feedback.
