Reference ramping
Acceleration and deceleration ramping times can be set individually for speed, torque
and frequency reference (
Menu - Primary settings - Ramps
).
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
. 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
.
Variable slope
Variable slope controls the slope of the speed ramp during a reference change. With
this feature a constantly variable ramp can be used.
Variable slope is only supported in remote control.

Special acceleration/deceleration ramps
The acceleration/deceleration times for the jogging function can be defined
separately; see section
(page
.
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).
