Reference ramping
Acceleration and deceleration ramping times can be set individually for speed,
frequency and torque reference.
With a speed or frequency reference, the ramps are defined as the time it takes
for the drive to accelerate or decelerate between zero speed or frequency and the
value defined by parameter
or
. The user can switch between two preset
ramp sets using a binary source such as a digital input. For speed reference, also
the shape of the ramp can be controlled.
With a torque reference, the ramps are defined as the time it takes for the reference
to change between zero and nominal motor torque (parameter
).
Special acceleration/deceleration ramps
The acceleration/deceleration times for the jogging function can be defined
separately; see section
.
The change rate of the motor potentiometer function (page
) is adjustable. The
same rate applies in both directions.
A deceleration ramp can be defined for emergency stop (“Off3” mode).
