Mot P Coef. PCC

Defines the ratio between the

nominal drive controller power

and the motor with the lowest

power rating when a logic input

is assigned to the motor

switching function (see

page 71).

[5]

• LF allows adjustment between 0.5 and 4 kHz using the

SFr parameter.

• HF1 and HF2 allow adjustment between 4 and 16 kHz:

HF1 is for applications with a low duty cycle, without

derating the drive controller. If the drive controller

thermal state goes above 95%, the switching frequency

automatically goes to 2 or 4 kHz (depending on rating).

When the thermal state returns to 70%, the switching

frequency returns to the set value.

HF2 is for machines with a high duty cycle with derating

of the drive controller by one power rating. The drive

parameters (current limit, thermal current, etc.) are

automatically scaled.

= drive controller constant torque output current rating shown on the drive controller

nameplate.

The factory setting depends on the macro-configuration used: No for Material

Handling, Yes for General Use and Variable torque.

This parameter is not available on 125–500 hp drive controllers.

Refer to the drive controller instruction bulletin, VVDED397048US, for duty cycle

ratings of the drive controllers.

★ These parameters are available only with the I/O extension card installed.
