Precautions
• The start accept flag turns on for axis during manual pulse generator operation. Positioning control or home position return
cannot be started using the Motion CPU or MT Developer2. Turn off the manual pulse generator enable flag after the
manual pulse generator operation end.
• When the torque limit value is not specified with M(P).CHGT/D(P).CHGT (torque limit value change request instruction form
the PLC CPU to the Motion CPU), or CHGT (torque limit value change request), the torque limit value is fixed at 300.0 [%]
during manual pulse generator operation.
• If the manual pulse generator enable flag turns on for the axis for which the start accept flag is ON, a minor error (error
code: 192AH) occurs, and manual pulse generator input is not enabled.

• If another axis is set and the same manual pulse generator enable flag turns on again during smoothing deceleration after
manual pulse generator enable flag turns off, a minor error (error code: 198EH) occurs, and the manual pulse generator
input is not enabled. At this time, include the start accept flag OFF for specified axis as an interlock condition for turning ON
the manual pulse generator enable flag.
