P4.1.15
250
Decel Time 2
1,2,3
RW
Use this parameter to set the time required for the output frequency to accelerate from the zero frequency
to the set maximum frequency . These parameters provide the possibility to set two different acceleration/
deceleration time sets for one application. The active set can be selected with the programmable digital
input.
P4.1.16
267
Power Loss Function
1,2,3
RW
Use this parameter to enable or disable the power loss ride thru function. When enabled the drive will stop
the output voltage to the motor allowing motor to coast down but PWM active to feed power back into drive
to keep the drive powered up as long as it can before power is lost. The drive will accept restart and safely
control the motor in the time set without cycling the run command if input voltage returns. This mode is
engaged at the following levels - 230V - 156.8Vdc, 480V - 303Vdc, and
575 - 426.65Vdc.
1 = Enable power loss function
0 = Disable power loss function
P4.1.17
268
Power Loss Time
1,2,3
RW
Use this parameter to set the allowable power loss max time before the drive will not auto restart when
power is reestablished and run command active. If AC input voltage recovers before this time expires, drive
shall continue to operate.
P4.1.18
2444
2
nd
Stage Ramp Frequency
1,2,3
RW
Use this parameter to define the frequency level where the drive enables the 2
th
Stage Ramp Frequency
output function. This then can be used for other inputs or devices to signal a frequency level.
P4.1.19
2667
Run Remove Stop Mode
1,2,3
RW
If the user opens the run enable or start/stop logic run enable, then it follows the parameter set to stop mode.
P4.2.1
254
DC-Brake Current
1,2,3
RW
Use this parameter to set the amount of DC current as an amp value that is injected into the motor during DC
braking.
P4.2.2
263
Start DC-Brake Time
1,2,3
RW
Use this parameter to set the length of time the DC-brake is activated when the start command is given.
P4.2.3
262
Stop DC-Brake Frequency
1,2,3
RW
Use this parameter to set the frequency level in Hz at which DC braking starts during the
deceleration phase.
