connection should be used:

When connecting to a motor driver with high to low transaction, the following

connection should be used (5V is not isolated from the HyCNC-4P):

X/Y/Z/A Direction Pulses

High level(5V) represents positive direction movement and low level (0V)

represents negative direction movement. Each output can be used to drive 15mA

push and pull.

The direction of a two-phase stepping motor can be changed by swapping

connection of one of the coils. Therefore, the connection to the motor driver can

be either one of the above connections.

If the motor direction can’t be changed by an external switch, the first connection

should be used for the motor moving position direction when the direction input

is driven and the second connection should be used for the motor moving

position direction when the direction input is not driven.

PWM Outputs

PWM1 and PWM2 have same base frequency (0.017-100000Hz adjustable by

software). PWM1’s duty cycle is proportional to spindle speed and PWM2’s duty

cycle can be adjusted by a M code. 0% duty cycle is low level and 100% duty cycle

is high level output. Each output can be used to drive 15mA push and pull,
