Hi Both

Thanks, Craig for the information. It's a little over my head but only had chance to read it once. Will go through it again and absorb. I always like to understand how something works as it makes it so much easier to fix when it goes wrong.

Thanks for the info Allan. The manual says to adjust RV1 first until the motor stops moving at 0v. Then apply max speed 10v and adjust the command gain RV2  until the desired speed is reached. The way I am reading it is RV2 controls the max speed you want not RV1. Please correct me if I am wrong or is the way you're saying a better option?

Cheers
Mick

Thanks Craig

I will remove the motor tonight and start again without the Tach connected. Once I have matched the voltage from the Tach to the Command I will try reconnecting. This couldn't be some kind of phasing issue? Eg swapping two wires on a three-phase motor makes the motor run opposite. Just thinking if the motors are turning opposite to what the controller thinks they are would the Tach be running the wrong way?

Hi Both

Couldn't resist having another go. Don't know why but disconnected the Tacho Wires from the drive and the Motors run at full speed. Fully controllable from speed commands in Mach. I think means the drives and Motors are working fine. Any suggestions why this might be happening? 

Cheers
Mick

Hi Allan

Thanks again for your time. I will try this again tomorrow. I am convinced this is a setup error as these motors and drives were working perfectly before an error occurred on the OT Control and shut the machine keyboard down. It's not a problem to swap the motors over so will try this if Adjusting the Kp doesn't work. If all fails I will send one of the drives to be tested. They offer a fixed fee repair on the drives for £150 so if they were both faulty it wouldn't be the end of the world.
Don't want to give up on them just yet. the machine has done very few hours. 

Cheers
Mick

Hi Allan/ Craig

Craig can you simplify the wiring suggestions from your last post please.

Done some more checks and the Voltage at the bus is 103v when under load. A drop of 5v so I presume this is ok.
The interesting thing is no what speed command is entered in mach the voltage at pins 1 and 14 (Command Hi Low) is always 10.50v. This is from a speed input of F10 to F1000.

Cheers
Mick

Hi Craig

Thanks for your input on this. Can you simplify it a little more, please? I have attached the CSMIO page for I/O connector. I presume red will be high and blue low? At present, I have connected the red and blue wire to pins 1 and 14.
Is TB3 pin 4 on the servo drive? There has never been a wire attached to this pin.  

Cheers Mick

Hi Both

Sorry for the delay. Heres what we have.

Sem MT30H4-33 Motors
Norwin 2110 drive

Encoders:
 A+ Brown pin 1 ON CSMIO
A- Yellow Pin 14 ON CSMIO
B+ Red Pin 2 ON CSMIO
B- Green Pin 15 ON CSMIO
Z+ orange Pin 3 ON CSMIO
Z- Blue Pin 16 ON CSMIO
5VDC White Pin 4 ON CSMIO
GND Black Pin17 ON CSMIO

Tacho Connected to pins 1 and 2 on the Servo Drive card going directly into the motor. This has not been touched, it is the original wiring.

Command Hi and Low going to pins 1 and 14 on the I/O of the CSMIO. The wiring for this has not been touched either on the servo side.

I have 108vdc at the bus on the drives.

The Only wires that have been disconnected are the Command Hi-Low and the encoder.

Am I right in assuming that the 5vdc on pin 4 of encoder channel 0 supplies the 5 volts to the encoder?

There are only two wires coming from the command Hi-Low. This is the original wiring. I am not sure what you mean by single end wiring and configuration for this?

Could this be anything to do with Peak Current Limit pot on the personality module? Haven't tried adjusting it as they were fine before.

Thanks for your time on this.

Mick

Hi
Yes tacho is installed. The motors are mt30. The wires I am using for the speed command are command HI low.
I can check the bus voltage when I get home. Pretty sure it's 130v when I checked it before.

Really appreciate your time on this. I'll post anything I get back from Denford.
