Operating Instructions, 08/2013, 6FC5397-8EP40-0BA0
Description:
Backlash on reversal between positive and negative travel directions.
Input of the compensation value is
• positive, if the encoder is leading the machine part (normal situation)
• negative, if the encoder is behind the machine part.
Backlash compensation is not active when 0 is entered.
Backlash compensation is always active after reference point approach in all
operating modes.
Special cases:
A specific backlash on reversal must be entered for each measuring system.

MD30200 $MA_NUM_ENCS (number of measuring systems)
MD36500 $MA_ENC_CHANGE_TOL
(Maximum tolerance at actual position value change)
Description: Evaluation factor for backlash.
The machine data enables the backlash defined in MD32450 $MA_BACKLASH to be
changed as a function of the parameter set, in order to take a gear stage
dependent backlash into account, for example.
