I need to run my PID faster than 60 Hz

I need to run my PID faster than 60 Hz

For applications that require more pressure out of a pump or more flow out of a fan we can overspeed the motor slightly above the 60Hz base frequency. It should be noted that torque drops off at a rate 1/f when running above base frequency. Therefore, we cannot overspeed the motor too far over base frequency. See the below graph.

Below are a couple of parameter sets for running a motor at 63Hz.

Overspeeding an LS VFD
  1. DR20=63Hz
  2. IN01=63Hz (if using an analog input)

Overspeeding an LS VFD running PID
  1. AP29=63Hz
  2. DR20=63Hz

If a speed limit is being used, such as AD26, this must also be set to the new maximum speed.
