Hi,

I know this is not a Mach3 topic but I know there are a good few Mitsubishi users on this forum!

I have technical question on the Mitsubishi MR J2 drives. If I use the encoder pass through from the CN1A socket what is the spec on the signal. I presume its  square wave. I have a Heidenhain controller that requires a sine wave 8-14 ua signal from the encoders which are incremental Rod456 Heidenhains at the moment but was looking at fitting these MR J2 Mitsubishi drives and using the pass through to the Heidenhain.

John.

Heidenhain controller should be very happy with Mitsu CN1A "universal " output
Encoder A-phase pulse (differential line driver)
Encoder B-phase pulse (differential line driver)
Encoder Z-phase pulse (open collector)
Control common

With is what you need :-)
Beware: high frequency on this outputs ( 8MHz+ at 3000rpm motor speed) hens long wires cannot be used.

Sorry overlooked yours have sine wave  inputs - not compatible.

Mitsu use a serial communication system, between motor and drive, MD/MDR and MR/MRR are the two info channels and  no exact "pass through encoder signal" per say.
