The PWM signal is NOT going directly to the spindle motor): a) Make sure you have the right Port/Pin settings in Mach3 (see example settings below) b) Set D032 to 1 c) Make sure switch next to PRT is set to "PC" d) Very important: On Mach3 User Panel, make sure you select and input the max spindle speed (i.e.
#Mach3 software hacks manual
1) Reset the VFD to factory settings a) Set D001 to 1 (may be able to skip this step) b) Set D176 to 1 and press Func (this resets VFD to factory settings) 2) Reset the VFD to 400Hz max operating frequency rather than the 50Hz default: a) Set D002 to 400 (need to set this before D000) b) Set D000 to 400 c) Set D003 to 400 d) Set D009 to 400 e) Set D021 to 400 f) Set D093 to 400 3) Set VFD to receive input frequency setting for spindle throttle control from the AVI terminal: a) Set D031 to 1 4) OPTIONAL but I would recommend for additional debug/safety reasons: Set VFD to allow manual spindle "stop" from terminal even when running from PC 5) OPTIONAL: Set AVI terminal to readout spindle rpm instead of VFD frequency: a) Set D039 to 1 6) To run the spindle manually with variable speed directly from the AVI terminal: a) Set D032 to 0 b) Make sure switch next to AVI terminal is set to "Manually" b) Use AVI " Pot Dial" to set spindle rpm c) Use AVI "Run" to start spindle d) Use AVI "Stop" to stop spindle or turn down Pot Dial to 0 7) To run the spindle from the PC (note the PWM signal from Mach3 adjusts the setting of the AVI terminal as if it were the VFD Pot. (Note I didn't change the 220V setting to 110V in the VFD since there isn't a mechanism for generating higher voltage than the VFD supply and it doesn't appear to be necessary, but this should be vetted by another party (CHIMERA1960?) prior to long duration running). The post: "I finally figured out the VFD and Mach3 software settings for my 1.5 kW, 110Vac, 400Hz Spindle with the PRT-E1500W VFD in order to run the spindle either in manual mode or with PWM control through the PC.

#Mach3 software hacks update
Then I’ll update this (probably start a new thread so it can be found more easily) with pictures & arrows and skip the “use seconds in Sheetcam” as you noted. I’ll be using the new post to cut a couple of things for someone this weekend and will make sure it’s not doing anything bad. 3 which is what Mach3 fails on if you’re doing seconds in Mach and if you had G04 milliseconds checked in Mach that would be treated as. I’m converting that to ms in the post (the default doesn’t - it just leaves.

My version of the post knows that and always outputs in ms. Sheetcam sends a value to the post in seconds regardless of how you specify the units in your tool definition. 30 and post processed using your modified post and it still output using milliseconds.Īctually that makes sense the way I coded the post. I went back to application options and set the TIME units to ms then edit my tools pierce delay to 300 ms instead of.
