٨Built-in pulse generator provides easy trapezoidal accel/decel drive using I/O controller or PLC.
precise positioning
Simple positioning control is possible together with RC-208A, RC-410 or PLC with built-in
Selection Table
٨The motor control by receiving clock pulses from the controller with built-in pulse oscillator can provide
counter, because clock pulses generated in the driver are output to the outside.
٨FREE input to turn off excitation current of a motor ̪1
٨PHASE OUT output for location of home for excitation timing ̪1
Since the deceleration start position is set automatically by the use of the GROW OUT signal
٨Auto. current down
when using it together with controller RC-208A or RC-410, positioning control is possible only

by the setting of the total pulse.
٨Free speed control is possible using external potentiometer and a joy stick, since arbitrary number
of rotations can also be set by an analog voltage.
