Hi, sounds like the start command is not being recognised at the digital input, do you have a sketch of the wiring, as I suspect there is a referencing issue. You can view the digital inputs on the BOP, by looking at r722, if you cannot see bit 0 toggling when you start and stop, then there is a hardware issue. If there is no relay between the PLC and the drive, and you are using the PLC 24V to drive the digital input, then the drive requires a 0VDC reference from the PLC as well. See the block diagrams attached, note, there are wiring differences between the MM420 and MM440, so be careful. Regards, Graeme AttachmentBlock Diagrams.zip (570 Downloads) |
