ITEM NAME:Stepper Motor Driver Controller PWM Pulse Signal Generator Speed Regulator Product Description Description: Descriptions: 1. This module is a pulse generating module, which supplies stepping driver as signal. If you want to control the stepper motor, you must also have a motor driver.Frequency measurement: PUL and GND ports can be measured. 2. PUL+and PUL-are positive and negative of the pulse; EN+and EN-are positive and negative of the enabler; DIR+and DIR-are positive and negative of the direction. The six lines are connected to the six ports of the driver corresponding to the pulse, direction and enablement respectively. Note that the ENA enabler on the controller must be connected to the driver in both positive and negative ways if the function of turn-on or stop is to be used. 3. 2 groups of power input, 2 groups only need to connect to one group of power supply.One group is connected to DC 15-160VDC.The other group was 5-12 VDC. If it is.There are jumpers on the board, and the default selection provided in the pulse frequency signal can be set. Included: 1 X PWM Pulse Signal Generator. PUL+and PUL-are positive and negative of the pulse; EN+and EN-are positive and negative of the enabler; DIR+and DIR-are positive and negative of the direction.
