Indicates ON when the exciting phase is at the origin position.

Rotation monitor output (MON)

In the full-step, outputs once for every 6 pulses. • The CW direction of the rotation of the stepping motor is the clockwise direction when viewing the stepping motor from the output axis side (flange side) . The CCW direction is the counterclockwise direction when viewing the stepping motor from the output axis side (flange side).

ON_100% of current rating when stopped

OFF Approx. 50% of current rating when stopped

Note 1) The temperature increase in the motor driver can be controlled by setting SL to OFF (approx. 50% of the rated current).

Note 2) The output torque when SL is OFF (approx. 50% of the rated current) is approx. 50% of that when SL is ON (100% of the rated current).

• The factory settings are shown in the figure above.

• Before changing the settings of the function selection DIP switches, turn off the source of the PM driver.

• When the DIP switch "C" = "ON" (1/16 division), the internal circuit (stepping motor) operates at the rising edge and falling edge of the drive pulse. If the duty ratio of the drive pulse moves out of the adjustment significantly by 50%, operation becomes unstable.
