４－２．Setting STEP TABLE switch and STEP ANGLE SELECT switch
(1) Turn power [OFF].
(2) Set the step angle required by combining the S.T SEL switch
and the STEP SEL switch No.

●Step angles are theoretical values.
●Drive with two types of step angles are provided by combining the C.S signal.
●When the step angle is switched from the setting of 1000, 2000, 4000 or 8000
divisions to other number of divisions(1～800), change of the excitation position
may be caused.
Erroneous setting may cause breakage of
the machine or injury due to unexpected
rotation of motor.
Ensure correct setting.
The step angle is set up with the S.T SEL switch and
the STEP SEL switch.
The step angle can be selected from eighteen different
types of step angles.
Set S.T SEL switch with power OFF.
