This output indicates the initial step of excitation order of stepper motor and rotation position of motor axis.
This signal outputs every 7.2° of rotation of the motor axis regardless of resolution.
(50 outputs per 1 rotation of the motor.)
E.g.) Full step: outputs one time by 10 pulses input, 20-division: outputs one time by 200 pulses input.
This signal is for rotating motor's axis using external force or used for manual positioning.
When hold off signal maintains over 1ms as [H], motor excitation is released.
When hold off signal maintains over 1ms as [L], motor excitation is in a normal status.
※
Must stop the motor for using this function.
※
Refer to I/O Circuit and Connections.

Setting Microstep (microstep: resolution)
Setting Resolution (same as MS1, MS2)
The MS1, MS2 switches is for resolution setting.
Select MS2 or MS2 by DIVISION SELECTION signal ([L]: MS1, [H]: MS2)
Select the step angle (motor rotation angle per 1 pulse).
The set step angle is dividing basic step angle (0.72°) of 5-phase stepper motor by setting value.
The calculation formula of divided step angle is as below.
When using geared type motor, the angle is step angle divided by gear ratio.
Step angle / gear ratio = Step angle applied gear
E.g) 0.72° / 10 (1:10) = 0.072°
※
Must stop the motor before changing the resolution.
