Introduction
This product is a high‐performance micro‐stepping driver.
•
Smooth driverBy using micro‐stepping, this driver can achieved low‐vibration and low‐noise.
•
Built‐in overheat protection
A driver’s internal temperature in excess of 70˚C (158˚F) trigger overheat
protection, and the driver will stop working automatically.
•
Adjustable operating current
A digital switch adjusts the level of motor current during operation.
•
Bio‐polar driveBy using bio‐polar drive, this driver is powerful than uni‐polar driver and only
needs four wires connected to the stepping motor.
•
Automatic reduce current
In the stop state, the driver will reduce the current automatically to limit the heat
generated by the motor and driver.
