Hi JRoss I have another 2094 BMP5 but this one is with sercos in another machine, I have taken the servomotor and cables and plug it with this equipment in sercos And the servo gets really hard to move the servomotor shaft by hand , I just tried a little bit to move it, when the MSO is activated from direct command instructions. Im using the same servomotor with the same cables at the s kinetix 6500 . Is responding very nice to MAH and MAJ, with sercos servodrive So I think it may be the IBJT s that are not fireing the signal to the servo, but I have check the U V W vs Bus+ Bus- , las time Ive check and the reading of diode were fine, no shortcuts U V W vs BUS - READINGS diode 0.448 U - BUS+ OL WHEN INVERTED LEADS or wires AT MULTIMETER 0.448 V - BUS+ OL WHEN INVERTED LEADS or wires AT MULTIMETER 0.448 W - BUS+ OL WHEN INVERTED LEADS or wires AT MULTIMETER U V W vs BUS + READINGS diode 0.448 U - BUS+ OL WHEN INVERTED LEADS or wires AT MULTIMETER 0.448 V - BUS+ OL WHEN INVERTED LEADS or wires AT MULTIMETER 0.448 W - BUS+ OL WHEN INVERTED LEADS or wires AT MULTIMETER I have also check the readings of the IBJT s at kinetix 6000 sercos and the same readings of UVW vs BUS + and BUS- Best Regards -

The servo in not moving something heavy, is very light the load You can feell that the servomotor shaft is even harder to turn than the load , the load is very very soft The servomotor is an MPL-B1530u-EJ72aa The servo drive is a 6 kw and in the manual Design User, it says that is OK to use this servo with this servodrive, is in the list of useable motors Right now the servo is not connected to the load, and Is displaying S55 any way, I have tried to do Home to sensor, , MAJ , MAM, Direct commands , with out being connected the servo to the load -

Ok I did, and also cleaned the conectors, they look shiny like new, I ran a test but no changes , still fails I have another servomotor with cables , Ill change them and Ill let you now Best Regards -

Is an existing system MPL-B1530U-EJ72AA Yes Im using 2 signals from connector DB 44 the the input for enable and the input for home sensor Best Regards -

Yes, I have turned it in both directions, the lecture or readings of encoder at actualposition tag increases and decreases the revolutions normally Yes , when the MSO is on, I can turn the servo by hand, but no more than 1 rev , after or around 1 revolution the fault appears s55, I can move it back and forth , but no more than 1 rev, after that it fails and shows s55 velocity error, it doest fell hard I have check the power rail terminals, the Dc volts lines in power rail takes DC to the output side of the kinetix 6500, I was thinking that there may not be DC 640 volt , but there it is in power rail Best Regards -

Hi JRoss This is part of what I have check I did, and i can see the encoder readigs at actualposiotion tag changing , The servo was moving before, responding to autotuning, test, MAH, MAJ , MAM instructions and direct comands, I have check lines with encoder and power lines and readings, and they look normal. All lights are green, the bus led is green and steady, When the servo is activated with MSO instruction, the servo is loose, I can turn it by hand, no alarms. but when I try to move it with MAH or MAJ , for example , then the S55 appears, I have also check the inputs L1 L2 L3 with the bus + and bus- and i have normal readings, also U V W with bus + and bus - and also normal readings, with my muitimeter to check diode at rectification and BJTs . And when the kinetix is on I get around 640 volts DC ant BUS + and Bus - I was thinking that it could be the BJTs that are not fireing signal to the servo and the error might be because the dirves tries to move the servo, and it doesnt move , sp there is a difference and gives the s55 error. I have check the BJT installed, with multimeter, the block of BJT give normal readings UVW with Bus+ and Bus - , I dond see shorts just the normal readings of diodes, Best Regards -

HI , I would like to ask you for your opinion THIS IS MY PROBLEM WITH THE kinetix 6500 The equipment was working fine , but now i cant make to servo move with the program, cant run the test or autotuning Status in front of servo drives say running. Everything is green, no errors, when I activate the MSO I can hear a click at servodrive, but the servo is not energized, because i dont hear the usual noise when the servo is energized, I have check the cables and conectors, everythig is fines, I check the servo resistence , no shortcuts or open lines, The wierd part is when the servos are in the running state i can move by hand, they are supossed to be locked. after that I activate the home MAH, or test or autotuning , or a direct command ,and then it fails When i try to jog . move, test or autotuning the servo it says s55 velocity error or excess positon error, i can not get servo to move at all I can see the position from the encoder back to the plc. I have turned the servo and i see the position at actualposition Before the equipment was working , moving , I just swith it off one day, and the next day I couldnt make it move Best regards I have added the programm as an attachment k6500.ACD
