About inputting
Please use voltage less or equal 24V. When voltage ≤5V, no need external resistance R1. If voltage over 5V, please connect external resistance R1, and keep the driver input termial under 5V.When pulse signal stopping, please disconnect the signal input terminal.When on double pulse signal working, please do not use CW and CCW concurrent connections.Please convert running direction after pulse signal stopping.No need to connect EN terminal on normal conditions.
Power supply
1. please prepare enough power supply. When power capacity shortage, the following unusual condition will be happened:
When on high speed running, motor rotate abnormally.
Motor starting and stopping slowly.
Ensure motor working smoothly, please use over 75W for 42mm motors, over 100w for 57mm motors.
2. Please do not connect power negative reversed, otherwise the drive will be burned.
3. Power voltage typical value 24V or 36V.
