I have an Extron vertical machining centre, This is running Panasonic ac servos on each axis and a Fuji spindle controller.

Machine also has a 16 tool carousel.

Auto lube system.

So far l have only hooked up the motors to the masso with pulse + & pulse -, and direction a & b. I have changed program on servo drive however motors are not moving. I need to get power to motor, any ideas?

Can you please share the motor drives user manual here and also a list of parameters that you have set on the motor drives so that we can have a look.

Have attached manual for Panasonic drives. Am having trouble uploading pdf as it is 1.8mb.
I wired up the masso unit, 240v power supply and installed firmware. all working.


I have wired up driver to masso today on the 3 axis.

Removed cable from main board and made up cables to masso.

Please just put a link to the documentation.

So after connecting power to the motor drive, can you still turn the motor shaft by hand?

This was done earlier via email. Panasonic drives please connect the MASSO's STEP signals to PULS1 and PULS2 signals and DIRECTION signals to SIGN1 and SIGN2 as per page 29 of the drive manual. Please also note that you will have to program your drive to take these signals as per page 123, bottom of the page.

Have powered up machine with original controller, when powered am still able to turn motor, checked Z axis as easy to get to.

Link for drive,

Lets first check if the motor and drive are setup right and enabled.

So if you do not connect the drive to any controller and power on, is the motor shaft locked or you can turn by hand?

With the Z axis disconnected from servo drive and powered up, l can turn ballscrew.

With Z axis connected to servo drive and original controller powered up, it is possible to turn ballscrew also.

  1. So for the test we need to have the motor connected to the motor drive and then power up the drive, not connected to any controller.
  2. Check if you can turn the motor shaft by hand.
  3. If not then the motor is disabled and you need to connect Pin 29 (Servo ON) to Pin 41 (COM) as per the below and then see if the motor shaft locks.

I have gone to page (appendix) 78. this shows wiring of existing plug.

I have pulled plug apart and am not sure how to read numbering.

Color coding of wiring does not match up with diagram.

Pin 1 is bottom left row 1, 12 pins in row 1

Pin 12 is top left row 1, 13 pins in row 2

12 pins row 3

Pin 50 is top right row 4, 13 pins row 4

How is row 2 and 3 numbered compared to diagram?

I ended up purchasing a new plug rather than cut up existing cable.

I have connected pin 29 to 41 and am still able to turn motor.

I now have 12 vdc at pins 7 & 41. I have also connected 29 & 41,

Motor still rotates by hand.

As l am using a new/ bare plug am wondering if l should run a ground from pin 13 to cabinet. Could it be this obvious?

Page App 73 shows wiring of plug.

these drives have become a mission! We are doing exactly as per Page 32 and I am out of ideas.
  1. You know you you mentioned that the drives were working with old controller and maybe you can connect back and try to connect/disconnect the servo-ON connections manually to confirm that they work as we are thinking they should.
  2. Next please measure the voltage going to 7 & 41 pins from the old controller connected and motor enabled.
