Parameters 245
26.17 Torque ref filter time Defines a low-pass filter time constant for the torque
reference.
0.000 s
0.000 … 30.000 s Filter time constant for torque reference. 1000 = 1 s
26.18 Torque ramp up
time
Defines the torque reference ramp-up time, ie. the time for the
reference to increase from zero to nominal motor torque.
0.000 s
0.000 … 60.000 s Torque reference ramp-up time. 100 = 1 s
26.19 Torque ramp down
time
Defines the torque reference ramp-down time, ie. the time for
the reference to decrease from nominal motor torque to zero.
0.000 s
0.000 … 60.000 s Torque reference ramp-down time. 100 = 1 s
26.25 Torque additive 2
source
Selects the source of torque reference additive 2.
The value received from the selected source is added to the
torque reference after operating mode selection. Because of
this, the additive can be used in speed and torque modes.
Note: For safety reasons, the additive is not applied when an
emergency stop is active.
WARNING! If the additive exceeds the limits set by
parameters 25.11 Speed control min torque and 25.12
Speed control max torque, a ramp stop may be
impossible. Make sure the additive is reduced or removed
when a ramp stop is required eg. by using parameter 26.26
Force torque ref add 2 zero.
See the control chain diagram on page 591.
For the selections, see parameter 26.11 Torque ref1 source.
Zero
26.26 Force torque ref
add 2 zero
Selects a source that forces torque reference additive 2 (see
parameter 26.25 Torque additive 2 source) to zero.
0 = Normal operation
1 = Force torque reference additive 2 to zero.
