NOTE: CONFIRM MOTOR SUITABILITY FOR USE WITH DC BRAKING
DC Brake voltage (P174) is applied for the time specified by P175 with the following
exceptions:
• If P111=1, 3 and P175=999.9 the brake voltage will be applied continuously until a
run or fault condition occurs.
• If P110=2, 4...6 and P175=999.9, brake voltage will be applied for 15s
• If P121...P124=18 and the corresponding TB-13 input is CLOSED, brake voltage will
be applied until the TB-13 input is OPENED or a fault condition occurs.

mode
• 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)

40.0
20.0 Accel Boost is only active during acceleration
40.0 Increase P170 until the motor speed no
longer changes between no load and full load
conditions.
Max I • When the limit is reached, the drive
displays CL(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 current Max I (%)
In field weakening, the Current Limit is
inversely proportional to the speed.
60.0 Maximum time before drive trips into HF
fault.
50.0 Setting is a percent of the nominal DC bus
voltage.
