I am trying to integrate this system into my Geko540, Mach3, ESS smoothstepper current setup. Ive been doing a bench test, for 2 days, and finally have almost everything working properly. I dont have the spindle plugged in so I dont burn it up during the long debug sessions. I can control the speed of the spindle using the respective areas on the mach 3 screen. I verify by watchiing the frequency values on the VFD screen. Using a meter I also verify that my voltage turns on and off at DCM and FOR terminals. Zero voltage when I turn the spindle off using Mach 3

When I power up the VFD, with or without my system already powered up, the spindle will run up to 1200 hz. I can turn on the relay to the VFD and then control speed up and down but the speed never goes lower than 1200 even after I turn off the relay and shut off power to the 2 terminals. The only way to shut it off it to hit the stop button on the VFD.

PD000=0 for Parameter unlock ( 1 ) for Parameter Lock

PD001=0 (1 For Remote Control)

PD002=0 ( 1 For 0-10v Terminal Control or Remote Trim Pot Control )
( J1 Also Needs to be set for Terminal Control )

PD003=400

PD004=400

PD005=400

PD007=20

PD008=220 (120 If you have 120v VFD )

PD009=15

PD010=8

PD011=120 ( 100 Minimum Setting with Quality VFD, 120 is Safe)

PD13= 08 is for Factory reset, Only use this to set VFD to Factory Default Settings

PD014 Acceleration=12 ( Adjust to suit)

PD015 Deceleration=12 (Adjust to suit)

( PD15 is ignored IF PD26=1 Then the Spindle will Coast to a Stop)

PD141=220 ( Motor Rated Voltage ) (120 for VFD Rated for 120v )

PD142= ( Motor Max Amps)

PD142=( 220vSet for your motor Amp Rating 2.2Kw Spindle 9 amp )
PD142=( 220VSet for your motor Amp Rating 1.5Kw Spindle 7 amp )
PD142=( 220v Set for your motor Amps Rating 800w Spindle 4 amps )
PD142=( 120v Set for your motor Amp Rating 800w Spindle 7 amp )

PD143=2 ( Motor Number of Poles)

PD144=3000 (Max Motor RPM) =3,000= (24,000)

PD70=0 ( This may need to be set to 1 if Control Voltage is 0-5v )

PD72=400

PD73=120 ( 100 Minimum Setting )


The jumper is set properly. Im using 10V for signal, 120v for power. PD 1&2=1

I assume I have a parameter(s) wrong somewhere but I dont know which one. Im thinking that theres a minimum setting somewhere? Like I said the spindle will run at 1200 with or without Mach3, Geko and SS powered up so I assume its not a setting in one of those 3. I did verify that theres no voltage on the DCM and FOR terminals when the existing system is powered up prior to powering up the VFD.

Any help would be very much appreciated.
