Stepper motor driver STEP/DIR SMD-2.8DIN

Dimensions of stepper motor driver SMD-2.8DIN

Description of stepper motor driver SMD-2.8DIN

The stepper motor driver SMD-2.8DIN is controlled by standard signals STEP, DIR and ENABLE. The motor motion is allowed when a signal is present at the ENABLE input (this signal can be inversed if needed). Displacement of a stepper motor by one step or microstep is carried out along the edge of the STEP signal, in the direction specified by the DIRECTION signal. Setting the maximum current of the motor phases and the microstepping mode is carried out by microswitches located on the front panel of the driver.

The ENABLE input provides removal of the holding torque and de-energization of the stepper motor. This signal can be used for de-energizing phases during normal operation or in emergency situations.

FAULT output

The FAULT output signal is designed to monitor the state of the driver and allows you to track the occurrence of abnormal situations during operation. In the event of an emergency, the resistance between the FAULT terminals tends to infinity.

• Signal type - optocoupler output
• Maximum voltage - 48 VDC
• Maximum load - 50 mA
• Resistance of closed contacts in normal operation mode - no more than 100 Ohm

Connection of stepper motor driver SMD-2.8DIN

The stepper motor driver can be connected to a PNP or NPN open collector logic signal source. High-level voltage signals 5-12 V can be used without additional connections. 24 VDC control signals can be applied using a 3 kΩ current-limiting resistor.
