Thanks Jraef,
I have an ATV930D22S6 drive.
So its actually a 25HP VFD. (I wrongfully said 30HP earlier)
The motor name plate FLA is 19.3Amps
Current limitation is at 40.8(max of vfd)
Speed loop type is 'standard'
My torque ratio is set a 100%
Toque offset 0%
Torque control time out 60s
High...
The motor current is a 20FLA and the VFD current limit is 40Amps. I purchased 1 size up from the constant torque HP recommend.
In my scenario, the motor is a 20HP 575V motor.
I purchased a 30HP 575V constant torque VFD
I doubt my VFD is undersized... im just wondering if to start the motor...
I have a Chain belt conveyor that is controlled by a VFD.
It lacks the input current to get going, here is scenario.
Motor is 1800RPM FLA = 20Amps
Across the line it starts up fine and pulls 12Amps after start-up.
On the VFD it hmms but doesn't have sufficient In-rush current to start.
We...
