After disconnecting the on/off connections, finally my motors moved. Thank you so much bob

I follow your dip switches configuration. But there is same responce... the voltage on step pin is 0.06 for 15% jog rate. And exceeds as the jog rate exceeds.
thinking that may be pmdx is not working fine , I tried to drive the motor using arduino mega 2560 by generating a 38khz step signal on pin (pwm)13 ". But again the clock LED on motor "ON" but the motor don't move. Even there is no jerk producing in the motor.

When the motors move in the positive direction the direction led(s) go OFF.
The step LED is on pmdx126 (I.e the led(s) for pin 2 4 6 and 8)

And yes exactly the step pulses are too narrow.  There is a dim glow on those LEDs when that motor is moving.

Motors was connected to the drive mechanism.but then I losned it to check their motion.
The X-axis slave motor needs to.be rotate in.the opposite direction as the master. And thanks for guiding about how to reverse its motion.

And ok I will try these dip switches setting and will.inform.you with the updates.

BOB

sorry I couldn't sent you file yesterday. here is the attachment

I checked the signals using digital multi meter by checking the voltage on direction and step pins.
The wiring for the other 3 motors is same as the main X axis motor.
The SmartBOB plug-in configuration assigned step signals on pins 2, 4, 6 and 8 and direction on odd pins.

And when motors move in negative axis then direction LED on pmdx-126 ON. And step LED also ON in both positive and negative axis.
Now today I checked the only x-axis motor which was moving before, showing the same behaviour like others. and also the motors are not moving in pmdx "test mode"

(1) yes I am using PMDX SmartBOBs motion device

(2)  I am using 3 boards. pmdx-410 for mach4, pmdx-126 for driving  motors and pmdx-107 for vfd-spindle. the stepper motors I am using are http://www.anaheimautomation.com/products/stepper/stepper-integrated-item.php?sID=51&pt=i&tID=132&cID=50
with builtin motor drivers. 

the connections are:
pmdx port J4            motors
5V                            on/off positive
GND                         on/off negative, direction negative, step negative
2                               step
3                               direction


and similarly rest of the ports j3 j2 j1 with rest of the three motors

for powering the motors  I am using 80VDC power supply.
 
(3) yes, I am using Ethernet cables connect the step and direction signals from the pmdx-126 to motor drivers.

hey

I have an issue with y and z axis motors. when I jog the motors only x-axis motor run. the rest of three motors that is x-axis slave motor, y-axis and z-axis don't run. I checked the step pulse and direction signal which motors receive but motors shaft do not move. I triple checked the settings in mach4.
when i connect the x-axis control cable to rest of three motors individually it run properly. so should the cables are not working properly or the motors.
I am using pmdx-126. and the control cables are lan cables. its like I am using the 6 core cables having different core colour

ohh.. Thank you soo much Steve. Actually I was thinking the same that if  I am using VFD then I don't have to use SSR.

Thanku :)

Hey...!!
I have done with almost complete wiring. and now I am using 3 phase Solid State Relay to connect vfd with spindle. And I am having issue in understanding wiring of SSR. The picture below is the SSR that I am using. Its 4 output terminals  are 1L1 2T1 3L2 4T2. so how would I know that  which terminal is for what purpose.? Or which terminal should connect to which terminal of spindle.
I have single phase VFD and 3 Phase spindle.

I set soo many rejisters. but mach4 is not controlling VFD.. I am gonna attach some photos of my VFD manual

I have HAUNYANG INVERTER of HY-M0D4A type. And i checked its manual.. rejister PD045 is for 'FOR' and PD045 is for 'REV'. and there factory setting is 2 and 3.
So i guess now I don't have to set any rejister for this..
Am i rite?

Bob,

Thank you. it helped me alot understanding VFD. I am gonna set the rejisters. amd will inform you after setting this.

Thanks bob

And how can I register PD045 and PD044??

I am also working on this VFD. but I am using PMDX 107... so i need wiring diagram of VFD with PMDX-107
