Description
Defines the shape of the acceleration ramp at the end
of the acceleration. See parameter
acc 1.
Ramp shape at end of acceleration.
Defines the shape of the deceleration ramp at the
beginning of the deceleration. See parameter
Shape time acc 1.
Ramp shape at start of deceleration.
Defines the shape of the deceleration ramp at the end
of the deceleration. See parameter
acc 1.
Ramp shape at end of deceleration.
Defines the acceleration time for the jogging function
i.e. the time required for the speed to change from zero
to the speed value defined by parameter
scaling.
See section Jogging (page
Acceleration time for jogging.
Defines the deceleration time for the jogging function
i.e. the time required for the speed to change from the
speed value defined by parameter
to zero.
See section Jogging (page
Deceleration time for jogging.
In speed control mode, this parameter defines the
deceleration rate for emergency stop Off3 as the time
it would take for the speed to decrease from the value
of parameter 46.1 Speed
torque control because the drive switches to speed
control on receiving an emergency stop Off3 command.
In frequency control mode, this parameter specifies
the time it would take for the frequency to decrease
from the value of 46.2 Frequency scaling
The emergency stop mode and activation source are
selected by parameters
21.5 Emergency stop source
stop can also be activated through fieldbus.
Note: Emergency stop Off1 uses the standard
deceleration ramp as defined by parameters
23.11...23.19 (speed and torque control) or
(frequency control).
Emergency stop Off3 deceleration time.
Selects a source that forces the speed reference to zero
just before it enters the ramp function.
0 = Force speed reference to zero before the ramp
function
1 = Speed reference continues towards the ramp
function as normal
