This machine data in combination with the setting in MD34200
Description:
$MA_ENC_REFP_MODE (referencing mode) = 7 caus es a signal runtime compensation
in the negative direction of movement at a position determined by a BERO
(zero mark).
The typical total delay time of the BERO message path for overtravel in the
negative direction of movement is entered.
The time includes:
•
•
•
The periods of time depend on the hardware used. The default value is typical
for SIEMENS products. Adjustment by the customer is only required in excep-
tional cases.
Input of the minimum value "0.0" deactivates the compensation (only active in
combination with MD34200 $MA_ENC_REFP_MODE = 7).
The machine data is available for all encoders.
