3.4 Control signal connection
3.4.1 PUL, DIR port: connection for pulse command
The standard R series driver signal interface is in the form of pulse, and 3R60 can receive two kinds 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 3R60 driver can be used: 3.3V-24V (
no need to connect resistor
)
Pulse and direction (PUL + DIR)
Double pulse (CW +CCW)
3.4.2 ENA port: used to enable or disable
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 error state, ENA input can be used to restart the driver. Firstly, the fault is eliminated,
and then a falling edge signal is input to the ENA terminal. The driver can restart the power part and the
motor is excited.
The level logic of the ENA signal can be set to the opposite, with the logic being opposite to the above.
