Outputs”. Put a green tick on the “Spindle” row’s “Enabled” column. All other
columns are not used by HyCNC-4 P.
Then click on page “Spindle Setup” page. If there is no circuit to control spindle
rotating direction. Put a “X” on “Disable Spindle Relay”. If spindle’s rotating
direction can be controlled by a H-bridge consisted by 2 relays, 2 relay outputs
are needed. If spindle’s rotating direction can be controlled by a H-bridge
consisted by 1 relays, 1 relay outputs are needed and the other is set to the
undefined output. The PWM1 and PWM2 base frequency is calculated by
equation
25000 x 10
“PWM base Freq”value
The PWM1 and PWM2’s duty cycle is controlled by the hardware. Its accuracy is
has nothing to do with “Kernel Speed”.
