In some applications, lowering carrier frequency reduces

switching losses and increases bearing life in some motors.

LEESON provides an optional capacitor kit for lowering the

carrier frequency.

The default carrier frequency on FHP Series controls is

16kHz. Using one of the capacitors supplied in the kit, the

carrier frequency can be lowered to a range of 12kHz to 4kHz.

Note: Audible noise will increase when the carrier

frequency is lowered.

To lower the carrier frequency on all FHP Series controls,

install one of the following 2-pin capacitors on the board:
