Hi Allan

I ordered the CSMIO straight from CS labs. Not really sure what you mean as far as being original?  I have posted on the Denford forums to see if anyone can advise on tuning the drives as they are off one of there machines.
It does look like a drive issue but doesn't make sense??
Those mice can be a nightmare.  :-[8

Hi

Yes if you put a feed rate of say 5000 the controller puts 10v on the command Hi Low input to the drive. I have already tried a 9v battery and the speed doesn't increase any more than it does for a 1.5v battery. It does sound like a driver issue but they were working fine with the old controller. There was never an issue with the speed of the motors.

Set the motor output steps in Mach 3 to 2000. 2500PPR X 4/ Pitch 5mm. Set The CSMIO motion controller to 10,000 PPR. Done the auto-tune on the CSMIO. The X-axis now moves accurately within 100th MM.

Still cannot get the motor to run over 60 rpm?? The feed rate does not increase over approx F300. The CSMIO is outputting 10v when a high-speed command input is entered. 

Has anyone got any ideas?  Is it Mach 3 configuration, a servo drive problem or Configuration of the CSMIO?

Really could do with some help here. Thanks, Allan and Joe so far.

Thanks Joe.

Just been reading up on encoders. My encoders have A A- B B- Z Z- which I think makes them quadrature output. So if I understand correctly the PPR could be 2500X4 counting all edges. Making it 10000 pulses per revolution?

This is frying my brain.

Thanks, Allan

It says on the encoder PPR 2500. Nothing about lines. I'm setting Mach 3 motor outputs tuning steps to 500 and in the CSMIO I'm setting to 2500. (Should this be 500 as well)?

I'm having loads of issues.

Unable to increase the speed of the motors past around 300mm minute.
The motors are completely out of sync with mach3. Mach 3 gets to the correct position and stops whilst the motors carry on. I think it is due to the program having a higher speed command than the motors are delivering.
Tried to autotune in the CSMIO but it doesn't work. Left it running for around half an hour. I set the KP at 550 anything over that and the motor starts moving. The auto-tune took the KI over 100,000 and was still going.

I have attached a picture of the encoder. It's not that clear on the photo but definitely says PPR 2500.

Hi Allan

Yes, they are DC Servos. I now have movement of the X-axis . The way the manual tells you to set up the servo is to enable the drive with 0v and adjust RV1 on the drive until movement stops. It then tells you to apply max voltage (10v) to the drive and adjust the command gain RV2 on the personality module until the desired rpm is reached. The first part works but when applying 10v to the drive and adjusting RV2 it makes little difference to the speed. There are other adjustments on there as I said before but I don't fully understand what to do with them.

I have axis movement when I run a simple program but the speed is very limited to around 300mm minute.

The CSMIO manual says to set the steps within mach3 as follows for the motor tuning. PPR / pitch. My encoders are 2500ppr and I have a ball screw pitch 0f 5mm. This gives 500 which I have entered into the motor tuning in Mach 3. I understand you're not into Mach 3 but just giving you a rundown.

I'll try tuning the CSMIO controller and see what happens.

Appreciate your time on this thanks.

Hi Allen

What do you mean by auto-tune utility? I have the drive manual and it explains how to tune the drives. The command gain seems straightforward enough but as for the for others, eg Tach gain, Peak current limit, stability seems a little more involved.

The drives and motors were working fine on the old Fanuc Ot Control. The reason for the refit was due to an unknown fault on the operator panel. Is it more likely to be the tuning in the CSMIO rather than the drives themselves?

Cheers Allan

The encoder output is in the mach 3 configuration. I'm not sure if this is necessary at all?

It doesn't seem to mention it in the CSMIO/P-A manual.

Could this be a motor tuning issue? When the drive is enabled I can turn the motor by hand. There is a little resistance but not a lot. The motor hums a little at stand still. 

Cheers

Hi All

Wired up the x axis on the CSMIO/P-A controller and can't get any movement.

Encoder wired to channel 0
A+ A- B+ B- Z+ Z- GND 5 DC. All the wires are clearly marked and colour coded on the encoders.
Command Hi and Low connected to pins 1 and 14 on the analog I/O

Mach 3 Config

Motor Outputs
X Enabled step pin 2 direction pin 6??

Encoder output. Have enabled encoder 1 to port 10 but not really sure what else to do here?

If I disconnect The command Hi Low wires and put a 1.5v battery across the wires and the axis moves.

All the limit switches and emergency stop signal are wired and working correctly.

Would really appreciate some help. Never used servos before and have read the manual now about 5 times.

The controller is showing no errors just waiting for command.

Thank you

Thanks Allen

I have wired the encoder and Vrefs. Was just unsure about the 10v. I will give it try tomorrow. Little unsure about what to enable in ports and pins but will give it a go.
Thanks again.
