P4 .1.11
b
Ramp 2 shape
ID 248
Minimum value:
0.0 s
Maximum value:
10.0 s
Default value:
0.0 s
Description:
The start and end of the acceleration and deceleration ramps can be smoothed with these parameters. Setting a value of 0.00 gives a
linear ramp shape that causes acceleration and deceleration to react immediately to the changes in the reference signal.
Setting a value from 0.10 to 10.00 seconds for this parameter produces an S-shaped acceleration/deceleration at the start and stop of
the slope.
P4 .1.12
b
Accel. time 2
ID 249
Minimum value:
0.1 s
Maximum value:
3000.0 s
Default value:
10.0 s
Description:
These values correspond to 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 .1.13
b
Decel. time 2
ID 250
Minimum value:
0.1 s
Maximum value:
3000.0 s
Default value:
10.0 s
Description:
These values correspond to the time required for the output frequency to decelerate from the set maximum frequency to the zero
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 .1.14
ab
2nd Stage ramp frequency
ID 2444
Minimum value:
MinFreq Hz
Maximum value:
MaxFreq Hz
Default value:
30.00 Hz
Description:
When 2nd stage ramp frequency is the frequency level at which the drive will enable the 2nd stage ramp frequency output function.
This then can be used for other inputs or devices to signal a frequency level.
P4 .1.15
ab
Fult reset start
ID 2483
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = Start/stop after fault reset - the run command has to be cycled to restart after fault reset; or
1 = Restart after fault reset - the run command is still active after fault the drive will restart without re-sending command.
Description:
Defines how the drive run command responds after a fault reset command.
P4.2 - Brake.
P4 .2.1
ab
Brake chopper enable
ID 829
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = Disable - dynamic brake OFF; or
1 = Enable - dynamic brake ON.
Description:
If an external resistor is connected to the drive setting, this parameter to enabled will allow excess DC bus voltage to be bled off
through the attached resistor.
