Hi
I have a problem with setting frequency via Modbus RTU in Inverter 8000B. I've set in 8000B : - Control command source: F0.01 = 2 (Communications RS485) - Master frequency source X: F0.03 = 9 (Communication interface) To set inverter frequency by LX3VP I"m using 06H protocol function and 2000H address with frequency value. I can see on the inverter display panel that it takes frequency from LX3VP. But when I send control command at 1000H address: Forward (01H) or Reverse (02H) or JOG forward (03H) or JOG reverse (04H) inverter runs always with minimum speed about 1.3 Hz.

Hello Petri,
I think You should send frequency to the F0.08 parameter.
I am working with modbus with some similar regulators like 8000B, and it works like this way.
Bye

Hello Petri, Please set the frequency for Invertor as Gavra said. |
