AXBB-E and Metronix APD-VS04NL Drives

[paulmacc21]

I have an old router table that was setup to run with Mach3 and an analog torque controller. Really don’t like Mach3 and am trying to get it working with a AXBB-E. Servo drives are Metronix APD-VS04NL and can be set to run with Step/Direction mode, which I have done. I worked out how to setup the drive then was lucky enough to find this youtube video, confirming the settings.

Had to use caption translate, but was good enough. He’s using Mach3 and an unknown controller, but using 5v logic for step/dir . I can get the drive to come out of Alarm state to the run screen “00000” and the motor to energize and lock, but not move. With frequency set at 200kHz (UNCNC) and motor speed set at 1500rpm, when I go to move the axis I get a steady 450Hz across 0v and output O9(Dir+) on the AXBB-E when NOT connected to the servo drive. If I connect the wire to the drive, but powered off, the frequency across 0v and output O9 becomes random between 80-100 Hz and powered on, it jumps thru 300-500Hz . I get not motor movement or indication on the servo drive LED that it’s receiving any step/dir signals.
So, either my youtuber has done something different/extra that I’m not aware of, or more likely I done something wrong! I have built a couple of cnc plasma tables successfully using a Masso G3 and Proma MyPlasm controllers, but this is the first time using a AXBB-E controller. That said I am FAR better at farming than I am at electronics!

Here’s my wiring;
Servo ------------------- AXBB-E
9 Step + --------------- O9 Step +
11 Dir - ---------------- O10 Dir –
10, 12 (Step-, Dir-) -- 0v(5v)
Pin 50 +24v in -------- +24v
Pin 19 CWLimit ------- 0v(24v)
Pin 20 CCWLimit ----- 0v(24v)
Pin 47 SVon ----------- 0v(24v)
Pin 18 Estop ---------- 0v(24v)

I've included some pics from the servo manual showing wiring for Position control, but they only show CW CCW logic, but there is a pic showing how to set it to step/dir, which I have done. They do mention resistors in the 3rd image, but my youtuber didn't mention them and I don't have the right size handy yet. I'm hoping I've made an obvious mistake that someone will see. I've tried swapping + & - around on the outputs and wiring -- to drive and ++ to drive, but get same result. I have left a comment on the youtubers video, but no response yet.

Generic Wiring for Position Control Using CW CWW logic

Change Logic to Step/Dir

Only example of 5v logic

I get a steady 450Hz across 0v and output O9(Dir+) on the AXBB-E when NOT connected to the servo drive

Was an error, should read "and output O9(Step+)"

Whoops,there is another example of 5v logic in the manual and I've included the other options that are shown

Still haven't been able to get things moving yet. If someone can see what I'm doing wrong I would appreciate the help. In the meantime I thought I would post all the Servo drive settings I changed to get that setup for Position control in case it can help someone else. My drive was running in Torque Mode originally, so in the drive menu you need to change;

PE-601 --> "2" this puts it into Position Mode
PE-320 --> "0" manual says to turn Zero Speed Torque Improvement OFF in Position Mode
PE-701 --> "2" or "5" Pulse/Direction mode. N Logic or P Logic
PE-609 --> "0" Acceleration time. Set to 0 so UCCNC can control it
PE-610 -->"0" Deceleration time. Set to 0 so UCCNC can control it
PE-702 --> "5000" Electronic gear N0. Set to 5000 until I can get it to move a calibrate it.
PE-703 --> "500" Electronic gear D0. Set to 5000 until I can get it to move a calibrate it.

Cheers

Hoping someone or CNCdrive support can tell me what I'm doing wrong. Thanks
