R130 User Manual
szruitech.com
The R130 driver can drive two-phase hybrid stepping motors below 130 frames.
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 Driver 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 Driver 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 signal interface of standard R series driver is pulse-shaped, and the R130 can receive
two types of pulse command signals.
The upper controller can be the pulse signal generating device, such as PLC, MCU, control
card and controller.
The pulse level that R130 driver can be used: 3.3V-24V (no need to connect resistor)
Pulse and direction (PUL + DIR)
3.4.2 ENA port: enable/disable
By default,when the internal optocoupler is off, the driver outputs current to the motor;
When the internal optocoupler is on, the driver will cut off the current of each phase of the
motor to make the motor free, and the step pulse will not be responded.
When the motor is in an error state, it is automatically turned off. The level logic of the
enable signal can be set to the opposite.
