Parallel Port breakout boards, motherboards, and dedicated accessories / PMDX-107 SPindle Speed Calibration question

« on: March 21, 2017, 04:21:44 PM »

How critical is it to perform this calibration? My spindle is running at almost max speed, 23560 rpm, with VR3 turned CCW all the way. This was based on a cheap non-contact laser tach.

Generic Spindle interfaces, I/O boards, Misc boards and panels / PMDX-126, PMDX-107 with ESS on a LSi C100 VFD

Hi guys,

Anyone out there has used the LSi C100 VFD (LSLV0022C100-1N) with a PMDX-126/107 and can share your connections from -107 to VFD?

I figured something like this (see image):

PMDX-107            LSi C100 VFD       
AGnd =====>  CM (Input signal common)
AOut =====>   AI (Freq. Setting Voltage signal input: 0-10V)
ARef  =====>  ???
COM =====>   CM (Input signal common)
Fwd Run ===>  P1 (FX: Forward Run)
Rev Dir ====>  P2  (RX:Reverse Run) Optional (is this needed on a cnc router?

220 single phase power to R(L1) and T(L3), Ground to chassis
Spindle Motor to U,V,W, and ground.

On PMDX-107 set the 10V dip switch (#6)
On PMDX-126 - not sure if I have to set to "Run in Normal Mode with Charge Pump", Config 1 open.
