I am working on a very old CNC with a Yaskawa Spindle Drive that is having problems. I was wondering if a common inverter with open vector control could replace that unit? All the wiring, specification, and operation look very similar to inverters I use everyday. Has anyone tried this?
Yes, the delays are always random.
Yes, the time varies every time and is not consistant.
The delay time varies from 0 to 2.0 seconds.
This happens all the time, on every system, regardless of drive quantity.
For example, if I have 4 drives and send a run command to all of them at once...
I am using Idec PLC's and Altivar Inverters. All components are usually very close together using twisted pair communication. I have not check the CRC error. I suppose this information is received by the Master and can be monitored there? Would this error information be specific about the...
I've been using Modbus RTU for some time know communicating from a PLC to various devices, including AC Drives. My biggest complaint is the delay between sending a run command and getting a response at the drive. This delay seems to be random in length and is always a problem whether I am...
