How is an Altivar VFD set to always run a particular speed when no reference input is connected?
Issue:
Wants the Altivar VFD set to always run at a particular speed when no reference input is connected.
Product Line:
Altivar 12, 32, 312, 61, 71, 212, 320
Environment:
All models
Cause:
VFD does not run the motor without a speed reference.
Resolution:
If there is no external speed reference when the VFD gets a run command, then it will always run at the minimum speed programmed to the VFD. Set the minimum speed parameter to the desired run speed. Use parameter LSP for the Altivar12, 32, 312, 320, 61, 71 drives. Use parameter LL for the Altivar 212 drive. These can be adjusted while the motor is running.
