Carrier Frequency See

Notes

0 4 kHz • As carrier frequency is increased, motor noise

is decreased

• Observe derating in section 2.3

• Automatic shift to 4 kHz at 120% load

• NEMA 4X (IP65) Models: Default = 0 (4kHz)

• NEMA 1 (IP31) Models: Default = 1 (6kHz)

1 6 kHz

NOTE

• P167 = rated motor frequency for standard applications

• P165, P168 = default setting depends on drive rating

Accel Boost 0.0 0.0 {%} 20.0 Accel Boost is only active during acceleration

Slip Compensation 0.0 0.0 {%} 40.0 Increase P170 until the motor speed no longer

changes between no load and full load conditions.

Current Limit Max I 30 {%} Max I • When the limit is reached, the drive displays

(Current Limit), and either the acceleration

time increases or the output frequency

decreases.

• Digital outputs can also indicate when the limit

is reached; see P140, P142.

• Refer to section 2.3 for the maximum output

In ﬁeld weakening, the Current Limit is inversely

proportional to the speed.
