NHP Posted April 10, 2021 Report Posted April 10, 2021 I want to drive a servo amp MR-J4 in position control mode by using pulse train signal. I have FX3U but i think it's source output type (common output is V+). Up on reading J4 manual, pulse train input to J4 is either open-collector type or differential type. I'm still a beginner and don't know that would it be possible to drive J4 with this FX3U. If possible, how should i do? Any help and advice is greatly appreciate.
glavanov Posted April 12, 2021 Report Posted April 12, 2021 (edited) J4 amps manifactured after Jan. 2015 with software version B7 have PP2/NP2 inputs for soure interface. Check section 3.6.1 from here: https://pl3a.mitsubishielectric.com/fa/pl/dl/9202/SH(NA)-030107-R.pdf If you are not lucky: Source_Logic_Servo.pdf Both wiring diagrams tested with MR-JE_A. It's the lighter version of MR-J4, but interfaces basiclly the same... Edited April 12, 2021 by glavanov
