(28) Stop Control Mode (SMOD)
One of the pulse motor general characteristics is that that the holding current in the stop mode is larger
than that for the AC servo-motor. Because of this, when the stop time is longer at the standby position,
the measure to reduce the power consumption at the stop mode is taken as one of the energy saving
measures.
SMOD = ON: Full Servo Control System is used in the standby condition.
SMOD = OFF: Standby Condition
x
Full Servo Control System
By means of servo control of the pulse motor, the holding current can be reduced.
The reduction level varies depending on the actuator type or load conditions. However, generally, the
holding current will be 1/2 to 1/4.
The actual holding current can be confirmed in the current monitor window in the personal computer
application software.
Note: Under the condition where any external force is given or depending on the stop position, slight vibration or
abnormal noise might be caused.
After confirming that there would be no trouble in whole system, use this signal.
