Hi,
I have an MCC with 2 ATV61 frequency converters of 22kW. Both VSD drive pumps, and are controlled by terminals including reference. Both VSD have the same parameters.
One VSD runs ok, but second VSD displays "CLi" message when it runs. I switched the motors, and first VSD runs OK with second motor (the message "CLi" does not appear). I switched the motors again, and I switched the control of VSD with problem on HMI control. I gave a run command, and I increased the reference from 0Hz up to 50Hz. At a reference after 1Hz the CLi message appeared on the display. The limitation current is set to 47Ams, and rated motor current is 38.8Ams. I don't know what can I do... Please help me.
Thanks.
