REMARK
•
One QD75MH module can be connected to one manual pulse generator.
•
The QD75MH module can simultaneously command to the axis 1 to axis 4 servo
amplifier by one manual pulse generator.
(axis 1 to axis 4 simultaneous operation is possible.)
Errors during operation
When the operation is stopped by the stroke limit (limit signal OFF), manual pulse
generator operation can be performed in the direction in which the limit signal turns
ON after an error reset. (An error will occur again if pulse input is provided in the
direction in which the limit signal turns OFF is turned ON.)
