Instar Stepper Driver adopts bipolar constant current chopper method to reduce the noise of the stepper motor and make the operation more stable. The increase of the driver power supply voltage greatly improves the stepper driver capability and high-speed performance of the stepper motor. When the stepper pulse stops for more than 100ms. The coil current is automatically halved to reduce the heat generated by the driver by 50%.  

Instar RS485 bus Stepper Driver integrates the intelligent motion controller function, which can control the motor d driver through Modbus' command. It has low vibration at low speed driving, high torque at high speed driving, and fast response to make it continuously operated.

Instar EtherCAT bus driver can completely replace the traditional pulse direction control driver in function. Supports Profile position, Profile velocity, Cylic synchonous position, Cyclic synchonous velocity, and Home.
