Stepping motor
2-phase STEPPING SYSTEMS
Specifications
Stepping motors with internal drivers
Features
1.Driver and motor are now integrated into a single unit.
A driver incorporating a motion control function needed
for driving a motor and a 2-phase stepping motor were
integrated into a single unit for enabling a more compact
installation space and less wiring.
2.Three types of operation modes can be selected to match
the specific application.
1Control by command pulses
2Program control by general-purpose I/O(Parallel)

Ex-factory setting is at 0 (rated value).
When there is a sufficient extra motor torque, lowering the operation current value will be effective in
the lower vibration. The Motor output torque is almost proportional to the current value. When adjusting
the operational torque, confirmthe sufficient operation margin and determine the Motor current value.
3. Current Select when Stop (STP)
The motor current value when stop and when power down input signal ON
(power low function is selected by dip switch) can be selected with this rotary
switch.
