Need Help Wiring SureServo SVA-2100 to Duet 2 Ethernet

[kzamani]

Hello everyone!

I am in the process of installing an MDPE-10 extruder onto an existing printer system. The system uses a Duet 2 Ethernet controller, sending step / dir signals to servo motors mounted on each axis.

The new MDPE-10 extruder requires the use of a Sure Servo SVA-2100 servo drive. There's a plethora of information for the servo drive located here: https://cdn.automationdirect.com/static/manuals/sureservomanual/sureservomanual.html

I can drive the servo motor using the controls on the servo drive, however the step / dir signals sent from the Duet are not turning the motor. Current motor configuration looks like this:

; Drives
M584 X5:6 Y7 Z8 E9  P:4			  						; Set drives for all axes to be driven from I/O port and CONN/LCD ports
M671 X-320:1566 Y603:603 S60 								; Set ball screw positions for probing routines, maximum error correction is 60mm or 3 rotations of the ball screw.	
M569 P5 S1  T2:1:0.25:0                           			; Drive 5 goes forwards - X axis 1 - timings for all motors based on clearpath servo drives
M569 P6 S1  T2:1:0.25:0                           			; Drive 6 goes forwards - X axis 2
M569 P7 S1  T2:1:0.25:0                           			; Drive 7 goes forwards - Y Axis 1
M569 P8 S0  T2:1:0.25:0                          			; Drive 8 goes backwards - Z Axis 1
M569 P9 S1  T5:5:5:5                           			; Drive 9 goes backwards - Extruder Drive 
M350 X16 Y16 Z16 E16  I1                           			; Configure microstepping with interpolation
M92 X320 Y320 Z320.00  E50	                   			; Set steps per mm
M566 X600 Y600 Z300  E80                   		   			; Set maximum instantaneous speed changes (mm/min)
M203 X24000 Y24000 Z2400  E12700            	   			; Set maximum speeds (mm/min)
M201 X750 Y1250 Z500  E250			  			   			; Set accelerations (mm/s^2)
M906 X800.00 Y800.00 Z800.00  E800.00 I30  		   			; Set motor currents (mA) and motor idle factor in per cent
M84 S30                                           			; Set idle timeout
 

The 5:5:5:5 timing is there strictly as a test, since I am unclear on the timings for this particular servo drive.

Any help would be greatly appreciated.

@kzamani Can you describe how you have the step and direction signals wired to the servo?

[kzamani]

@kzamani

I should note, I have the wiring as follows:

Duet 2 -> Duet Breakout Board
Drive 9:

Step + -> "Pulse"
Step - -> "/Pulse"
Dir + -> "Sign"
Dir - -> "/Sign"

Furthermore: The drive is configured to run in Pt mode, and is wired according to the diagram shown on page 20: https://cdn.automationdirect.com/static/manuals/sureservomanual/ch2.pdf

[alankilian]

@kzamani Which page is page 20?

[kzamani]

@alankilian ch2.pdf

Here's the overall wiring diagram for the system. It doesn't really drill down into how to wire the step / direction inputs for the servo drive, so I used my best judgement.

[alankilian]

@kzamani One further thing, do you have the drive enable signal (DI.1) connected to the internal 24 Volt signal?

And maybe DI.6 DI.7 and DI.8?

[kzamani]

@alankilian I do not. As I understand it, you can turn off the drive enable signal through the menu on the servo drive.

Same goes for DI 6 - DI 8

Everything is disabled.

[kzamani]

@alankilian I've connected DI-1 and DI-6 ~ DI-8 to the internal 24v power supply at "VCC". The servo drive screen shows "0"

[alankilian]

@kzamani I'll take a look at the manual tomorrow and see if I can learn anything.

@alankilian Thanks for your time, I really appreciate it.
