I am having a problem running my spindle after upgrading to Mach4 and a PMDX SmartBob 411. There is no response from the spindle on an MDI M3 command.
When I load a program file the spindle starts up but immediately stops. Could it be that there is no spindle feedback?
My spindle config is PWM on Pin 14 (Gecko540) at 75 Hz, rpm measured from index. PWM output polarity is Active High. (On active low spindle starts spinning when Mach is initiated)
My Inputs #1 through #4 are pins 11,12,13, and 15, with a "tick" in the Active Low col, Index is on Pin13, Motor Homes and Limits are on Pin11, Limit Override on Pin 12 and EStop on Pin 10, all with "tick" in the Active Low col
Output#1 is Pin 17 and Spindle On is Pin 1 with "tick" in the Active Low col. and Charge Pump is on Pin 16 (Gecko540) with a "tick" in the Active Low.
I have 0 in Min rpm in the Spindle tab and 3000 as max rpm.
On m3 s200 the spindle runs straight to around 2900. I have no control over changing the speed.
Any ideas?
I've attached my profile & the VFD wiring diagram for pins 5 throough 9.
