The original GE console cabinet has been removed. The new console consists of an LCD monitor, keyboard, and jog pendant, all mounted on a swing arm attached to the guard frame.
All control electronics are now in the rear cabinet.
Automatic control is provided for all the original Hardinge accessories:
The DC spindle motor has been replaced with a 7.5HP AC motor,
powered by a sensorless vector AC drive.
Rear electrical cabinet. Control computer is at lower right;
combined servo drive and PLC unit is center right; and spindle drive is
upper left.
The combined servo drive and PLC unit makes the control wiring much
simpler and more compact than it was in the
2002 Koyo-based version.
