Parameter

Name	Description
OnCompensation	The switch-on dead time to be compensated in seconds.
OffCompensation	The switch-off dead time to be compensated in seconds.
Hysteresis	The axis must have moved away from the switching point by this distance before reaching of the switching point is evaluated again. If a positive value is specified as dead time compensation, signaling is delayed. A negative value leads to leading signaling. The time cannot be adhered to precisely, if the controlling parameter changes with a fluctuating rate. If this controlling parameter is an actual axis position, the actual axis velocity must be constant.

Name

Description

OnCompensation

The switch-on dead time to be compensated in seconds.

OffCompensation

The switch-off dead time to be compensated in seconds.

Hysteresis

The axis must have moved away from the switching point by this distance before reaching of the switching point is evaluated again.

If a positive value is specified as dead time compensation, signaling is delayed. A negative value leads to leading signaling.

The time cannot be adhered to precisely, if the controlling parameter changes with a fluctuating rate. If this controlling parameter is an actual axis position, the actual axis velocity must be constant.
