Will be output at every interval of 7.2(deg.) for 0.72(deg.) 5-phase motor.
However, may not be output if the step angle is switched after power is switched on.

Note 1: Rotates at approximately 60 pps regardless of division setting. Rotates clockwise for clock 2, and rotation direction depends on R input for clock 1 (counter-clockwise when R input is "0").
Note 2: The automatic current reduction function reduces the current through the motor when the motor is stopped, to minimize generation of motor heat. Current is reduced approximately 150 ms after the last pulse input.
Holding torque also decreases when current reduction is in operation.

(1) While driving, if only one micro-step drive is used, set the number of divisions using digital switch M1.
(2) When two micro-step drives are used (to vary the forward and backward speeds for reciprocating motion, for example) set the number of divisions using digital switches M1 and M2.
Drive current settings
Set the current for motor operation by selecting the digital rotary RUN switch position as shown below.
