NC means no connection, so don't connect the ENA pins.

Also make sure that the CL57 is set for 5V inputs

Hi PWC,

What is NC, please? I have looked through the layout, there is a NC mark in TB2 ANALOG:



This is for my own understanding, I am not using this driver. My driver is CL57T which also has Enable pin.

Thank you. 

 

Dear All,
I have an old milling machine with a hydraulic spindle speed range switch. The hydraulic valve has 2 coils (low and high speed). There are 2 feedback inductive sensors (for low and high speed).
How can I solve this so that when a program needs to change the speed range, it does so automatically under the following conditions.
- the spindle can only rotate (in the between min-max range (50-3200rpm) if the inductive feedback corresponding to the speed
- the range can be changed by reducing the speed to 1-2 rpm
- low range (50-1500rpm)
- high range (1501-3200rpm)

I am looking for advice on how I can solve this properly. (I have never done this with Linuxcnc before)
