i have never seen those ancient amps in person, but, imho, the maintenance manual gives enough clues to get it running. and i see some legacy from it in modern mitsubishi servos... have you got READY-ON (RA1 relay should light up) and SERVO-ON (RA2 relay) signals asserted? i'm not sure, but it looks like you can set a speed command voltage with the VR1 pot when the ST1 switch is flipped. have you figured out the ZP1 pinout? 19,20 ER - despite the name looks like an analog voltage speed command input to me... 3,10 ERR - analog ground 1 SC - speed control? input? not sure, if it's an input (analog or digital) or an output... 7 ALM - alarm output 18 READY - either rdy-on input or output 13 SVON - should be servo on input 16 +24V (input?) 17 RG (digital ground?) /dmitry > > _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
