Relation to the pulse input mode switch
When the switch is set to the 1P position, motor rotation is controlled by pulse signals and
rotation direction signals.
When the switch is set to the 2P position, motor rotation is controlled by CW pulse signals
and CCW pulse signals.

• The shaded area indicates when the photocoupler diode is ON. The motor moves when
the photocoupler states changes from ON to OFF as indicated by the arrow.
• The pulse voltage is 4~5V in the “photocoupler ON” state, and 0~0.5V in the
“photocoupler OFF” state.
• Input pulse signals should have a pulse width over 5µs, pulse rise/fall below 2µs, and
a pulse duty below 50%.
• Keep the pulse signal in the “photocoupler OFF” state when no pulse is being input.
• The minimum interval time when changing rotation directions is 10µs.
• In 1-pulse input mode, leave the pulse signal at rest “photocoupler OFF” when
changing rotation directions.
• In 2-pulse input mode, do not input CW and CCW pulse signals at the same time.
Inputting a pulse signal while the other pulse signal is already in the “photocoupler
ON” state will result in erratic motor rotation.
