9-3-4 Setting the parallel drive system
When driving the linear motor with a parallel drive system, confirm that the following parameters are
correctly set for the (1), (2) 2-scale 2-motor (2-amplifier) control or (3) 1-scale 2-motor (2-amplifier)
control method. If incorrectly set, correct the setting and reboot the CNC power supply.
When using a parallel drive system, do not simultaneously DC excite the master side and slave side.
When carrying out DC excitation of either axis, make sure that current is not flowing to the other axis.
