Parameters 97
Defines the time required for the speed to change from the
speed defined by parameter
not
from
parameter
) to zero.
If the speed reference decreases slower than the set
deceleration rate, the motor speed will follow the reference.
If the reference changes faster than the set deceleration rate,
the motor speed will follow the deceleration rate.
If the deceleration rate is set too short, the drive will
automatically prolong the deceleration in order not to exceed
drive torque limits (or not to exceed a safe DC link voltage).
Notes
• Applicable only when
is disabled. If
parameter MPPT reference is enabled, then the parameter
should be set to it’s default value.
• If a short deceleration time is needed for a high inertia
application, the drive should be equipped with braking
equipment such as a brake chopper and brake resistor.

Displays the ramped and corrected speed reference (before
speed error calculation).
This parameter is read-only.

Displays the filtered speed error. This parameter is read-only. -
-30000.0… 30000.0
rpm
Filtered speed error.
See par.
Defines the time constant of the speed error low-pass filter.
If the used speed reference changes rapidly, the possible
interferences in the speed measurement can be filtered with
the speed error filter. Reducing the ripple with this filter may
cause speed controller tuning problems. A long filter time
constant and fast acceleration time contradict one another. A
very long filter time results in unstable control.
0 ms
0…10000 ms
Speed error filtering time constant. 0 = filtering disabled.

Shows speed controller output that is transferred to the
torque controller. This parameter is read-only.
0.0
-1600.0…1600.0%
Limited speed controller output torque.
