Mesa-Fanuc-PWM

yep. no +-10V signals. Requires 6 PWM channels per axis. 3 for CW, 3 for CCW.

Hi Andy, Thanks again for your advice,

I have no documentation on this, But I trust my friend's advice on Fanuc, as he is a Fanuc specialist. That is his business, to repair Fanuc Components, He used to be the service manager for Fanuc South Africa, and has about 20 + years experience on Fanuc. I'll find out from him if he can give me a copy of the documentation though.

Hi Andy,

I didn't manage to get any documentation from my friend so far. I want to continue though, and would like advice as to what hardware you would reccomend for me to continue? And is there any sample configurations for the pwm controlled servo's? I would appreciate your and Peter's assistance in this. Any advice would help. (Thanks)

I would love to know which mesa cards to use for pwm. Andy, you mentioned about a fpga card to use. What would you suggest? Will something like a 7i80DB work? together with a 7i75? I suppose I will need 30 I/O for a 5 axis machine with pwm. so my configuration for this machine can be as follows:
7i80DB => J2 => 7i75 => PWM
=> J3 => 7i75 => PWM
=> J4 => 7i77 => 7i84(SS)
=> J5 => 7i77 => 7i84(SS)

Would this hardware configuration work for the PWM red cap Fanuc servo drives?
Just to recap: I confirmed each drive has 6 PWM channels, 3-CW, 3-CCW. I need to drive 5 Axis on this machine.

I apologize.

I Understood it wrong. the PWM channels (I think ... ) should be as follow:
phase-A
phase-B
phase-C
phase-A-inverted
phase-B-inverted
phase-C-inverted
