3 Weeks AgoMuzzer replied to a thread Testing The VFD, Break Resistor and Wiring to AXBBE in Spindles & Drive MotorsHaha no, don't connect the resistor across DC+ and DC-. That is rectified mains voltage. You misread / misremembered the words "Braking resistor...30 replies | 7055 view(s)

3 Weeks AgoMuzzer replied to a thread Testing The VFD, Break Resistor and Wiring to AXBBE in Spindles & Drive MotorsI have to admit I took the easy way out and coughed up for a Yaskawa GA5 (latest generation) last time round. These are £390 plus £80 for the...30 replies | 7055 view(s)

4 Weeks AgoMuzzer replied to a thread Testing The VFD, Break Resistor and Wiring to AXBBE in Spindles & Drive MotorsIf you trust yourself, you could put your voltmeter across the braking resistor and see if any voltage appears across it during decel. As you say,...30 replies | 7055 view(s)

4 Weeks AgoIt says K1 and K2 are the tacho signal ie a DC voltage proportional to speed. I doubt that will be any use with modern drives. I have similar SEM...11 replies | 2037 view(s)

4 Weeks AgoMuzzer replied to a thread Testing The VFD, Break Resistor and Wiring to AXBBE in Spindles & Drive MotorsHaha yes, that wouldn't help. Did you lower the threshold voltage (parameter 01_31) to 600V (not critical but probably helps)? Brake utilisation rate...30 replies | 7055 view(s)
