A2: Various NC/PLC interface signals and functions
2.2 NC/PLC interface signals - only 840D sl
During "hold", clamping or standstill monitoring are active.
Note
The following error is suddenly corrected if the controller enable is set without complying with
the axial acceleration characteristic (speed jump).
Application example
Positioning response of machine axis Y following clamping when "controller enable" is set.
Clamping pushed the machine axis from the actual position Y
