Be sure to shut off the power
before using the pulse-input
mode selection switch.
The new pulse mode takes effect
when the power is turned on
again.

When the motor is to be controlled through 2-pulse signal input via the CW pulse signal and
CCW pulse signal, set the pulse-input mode selection switch to "2P."
When the motor is to be controlled through the PLS (pulse) and the DIR (rotating-direction) , set
the pulse-input mode selection switch to "1P."

Operating current

Use the operating-current adjustment switch "CURRENT" to set the motor's operating current.
Set the operating current as a product of the maximum driver output current "F," which is 100%,
multiplied by the operating current percentage corresponding to the given dial.
The switch provides a selection of 16 levels ranging between "0" and "F."
If there is extra torque, the current may be set to a lower level in order to suppress increases in
motor temperature.
Factory setting
[F]: Driver's maximum output-current value
