Ramp 2 shape
P4.1.11 b
Minimum 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.
Accel. time 2
P4.1.12 b
Minimum value: 0.1 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.
Decel. time 2
P4.1.13 b
Minimum value: 0.1 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.
2nd Stage ramp frequency
P4.1.14 ab
Minimum value: MinFreq.
When 2nd stage ramp frequency is the frequency level at which the drive will enable the 2nd stage ramp frequency output function.
Description:
This then can be used for other inputs or devices to signal a frequency level.
Parameter value can only be changed after the drive has stopped.

Parameter value will be set to be default when changing macros.

Motor control mode
P5.1.1 ab
Minimum value: N.A.
Options: 0 = Frequency control - Output frequency is controlled directly by the frequency reference.
1 = Speed control - Output frequency is controlled by giving a frequency reference to it with slip compensation.
