R60X3 user manual 2-- 6 -
szruitech.com
The matching motor of the R60X3 drive is the low resistance and low inductance hybrid
stepper motor.
The common 2-phase stepper motor’s lead number are 4, 8 and 6.
There is only one connection mode for 4 leads motor.
Series and parallel connection mode are used by 8 leads motor:
When series used, the winding inductance increased. The set of drive current should be about
0.7times than before. This is suitable for low speed required.
When parallel used, the winding inductance decreased. The set of drive current should be
about 1.4times than before. This is suitable for high speed required.
Parallel and central tapping connection mode are used by 6 leads motor:
When parallel used, all the winding connected, and the inductance was higher. This is suitable
for low speed required.
When central tapping used, half of the winding connected, and the inductance was lower. This
is suitable for high speed required.
3.4 Control signal connection
3.4.1 PUL、DIR Port: connection for pulse command
The R60X3 control signal is a pulse input and supports three-axis differential / pulse &
direction mode.
Pulse level is 3.3V ~ 24V compatible (no string resistor required)
Pulse & Direction（PUL + DIR）
3. 4. 2 ENA port: enable/disable
When the default optocoupler is off, the drive outputs the current to the motor. When the
internal optocoupler is on, the drive will cut off the current of each phase of the motor so that
the motor is in a free state, and the stepper pulse can not be responded.
When the motor is in an error state, enable disconnection. The level logic of the enable
signal can be set to the opposite by the debug software.
