Command filter setting switch (FIL)
Be sure to turn off the driver power before setting the function setting switch (SW1). The new setting
of the SW1 will become eff ective after the power is cycled.
Resolution
Set a resolution per revolution of the motor output shaft using the SW1-No.1 of the function setting switch.
OFF: 1000 p/r (factory setting)
ON: 10000
p/r
Pulse input mode
Set a pulse input mode of the driver according to the pulse output mode of the controller (pulse generator) used with
the driver. Set a desired mode using the SW1-No.2 of the function setting switch. The factory setting of the pulse input
mode depends on the destination country.
OFF: 2-pulse input mode
ON:
1-pulse input mode
Base current rate
Set the base current rate (%) for the operating current and standstill current using the current setting switch
(CURRENT). If the load is small and there is an ample allowance for torque, motor temperature rise can be suppressed
by setting a lower base current rate.
The actual operating current and standstill current are as follows.
Operating current: Maximum output current × Base current rate
Standstill current: Maximum output current × Base current rate × 0.5
The dial settings and corresponding base current rates are listed below.

Excessively low operating current or standstill current may cause a problem in starting the motor or
holding the load in position. Set a suitable current for your application.
