Speed additive
Defines a speed reference to be added after ramping.
Note:
For safety reasons, the additive is not applied when
stop functions are active.
Zero
Zero speed additive.

Max torq sp ctrl
Defines the maximum speed controller output torque.
-1600.0 … 1600.0%
Maximum speed controller output torque.
10 = 1%
23.10
Min torq sp ctrl
Defines the minimum speed controller output torque.
-1600.0 … 1600.0%
Minimum speed controller output torque.
10 = 1%
23.11
SpeedErr winFunc
Enables or disables speed error window control.
Speed error window control forms a speed supervision
function for a torque-controlled drive. It supervises the speed
error value (speed reference – actual speed). In the normal
operating range, window control keeps the speed controller
input at zero. The speed controller is evoked only if
• the speed error exceeds the upper boundary of the
window (parameter
), or
• the absolute value of the negative speed error exceeds
the lower boundary of the window (
When the speed error moves outside the window, the
exceeding part of the error value is connected to the speed
controller. The speed controller produces a reference term
relative to the input and gain of the speed controller
(parameter
which the torque selector
adds to the torque reference. The result is used as the
internal torque reference for the drive.
Example:
In a load loss condition, the internal torque
reference of the drive is decreased to prevent an excessive
rise of the motor speed. If window control were inactive, the
motor speed would rise until a speed limit of the drive were
reached.
Disabled
Speed error window control inactive.
0
Absolute
Speed error window control active. The boundaries defined
by parameters
are absolute.
1
Relative
Speed error window control active. The boundaries defined
by parameters
are relative to speed reference.
2
23.12
SpeedErr win hi
Defines the upper boundary of the speed error window.
Depending on setting of parameter
,
this is either an absolute value or relative to speed
reference.
0 … 3000 rpm
Upper boundary of speed error window.
1 = 1 rpm
No.
