Is it possible to use one variable speed drive to run multiple motors at one time?
Issue:
Is it possible to use one VFD to run multiple motors at the same time?

Product Line:
Altivar Drives

Environment:
All

Cause:
Running two motors on one drive.

Resolution:


Selecting a Drive for multiple motor control

-Each motor needs to be running all at the same time.
-Programming each drive  you need to sum the motor amps and HP for nominal motor current and rated motor power.
-The sum of the motor HP and motor FLA can not exceed the drives rated HP and nominal motor rated current.
-Each motor will need to have its own motor thermal protection device.

• Overload protection included for each motor
When connecting multiple motors to a single AFC, you must ensure that each motor
is provided with overload and/or over temperature protection in accordance with Article
430, Part C of the National Electrical Code, and any applicable local electrical
codes. Square D Class 9065 or GV2-M overload devices can provide this protection.
The overload/over temperature protective means must interrupt current flow to the
motor either by causing a shutdown of the AFC or by opening the circuit feeding the
protected motor.
