6. Parameter Settings
80
z Default standstill mode (No.53 CTLF)
This parameter defines the power-saving mode to be applied when the actuator stands by for a long time while
the machine is operating; the actuator stands by for a long time after completing home return operation; or the
actuator stands by for a long time after completing positioning operation in the numerical specification mode.
Define whether to enable or disable power-saving in parameter No. 53.
Setting
All power-saving modes are disabled. 0
Full servo control mode 4
The factory setting is “0 [Disable].”
Full servo control mode
The pulse motor is servo-controlled to reduce the holding current.
Although the exact degree of current reduction varies depending on the actuator model, load condition, etc.,
the holding current decreases to approx. one-half to one-fourth.
Since the servo remains on, no position deviation occurs.
The actual holding current can be checked in the current monitor screen of the PC software.
