Publication 22C-UM001I-EN-P
Advanced Program Group (continued)
A174 [Maximum Voltage] Related Parameter(s): b004, A171, A172, A173
Sets the highest voltage the drive will output.
Values Default: Drive Rated Volts
Min/Max: 20/Drive Rated Volts
Display: 1 VAC
A175 [Slip Hertz @ FLA] Related Parameter(s): P033
Compensates for the inherent slip in an induction motor. This frequency is added to the commanded
output frequency based on motor current.
Values Default: 2.0 Hz
Min/Max: 0.0/10.0 Hz
Display: 0.1 Hz
A176 [DC Brake Time] Related Parameter(s): P037, A177
Sets the length of time that DC brake current is “injected” into the motor when P037 [Stop Mode] is set
to either 4 “Ramp” or 6 “DC Brake”. Refer to parameter A177
[DC Brake Level].
Values Default: 0.0 Secs
Min/Max: 0.0/99.9 Secs (A setting of 99.9 = Continuous)
Display: 0.1 Secs
A177 [DC Brake Level] Related Parameter(s): P037, T051-T054, A176, A178
Defines the maximum DC brake current, in amps, applied to the motor.
Values Default: Drive Rated Amps × 0.05
Min/Max: 0.0/(Drive Rated Amps × 1.5)
Display: 0.1 Amps

ATTENTION: If a hazard of injury due to movement of equipment or material exists,
an auxiliary mechanical braking device must be used.
ATTENTION: This feature should not be used with synchronous or permanent
magnet motors. Motors may be demagnetized during braking.
