Description
Defines the torque reference ramp-up time, i.e. the time for
the reference to increase from zero to nominal motor torque.
Torque reference ramp-up time.
Defines the torque reference ramp-down time, i.e. the time
for the reference to decrease from nominal motor torque to
zero.
Torque reference ramp-down time.
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
25.12 Speed control max
be impossible. Make sure the additive is reduced or
removed when a ramp stop is required e.g. by using
parameter 26.26 Force torque ref add 2
See the control chain diagram on page 652.
