Parameters 231
Enable
1.
1
Source selection (see
). -
When speed error window control (see parameter
Speed error window control enable
) is enabled, this parameter
determines whether the speed controller only observes the
proportional term instead of all three (P, I and D) terms.
Normal speed
control
All three terms (parameters
,
and
observed by the speed controller.
0
P-control
Only the proportional term (
) is observed by the speed
controller. The integral and derivative terms are internally
forced to zero.
1
Defines the upper boundary of the speed error window. See
parameter
Speed error window control enable
.
0.00 rpm
0.00 … 3000.00
rpm
Upper boundary of speed error window.
See par.
Defines the lower boundary of the speed error window. See
parameter
Speed error window control enable
.
0.00 rpm
0.00 … 3000.00
rpm
Lower boundary of speed error window.
See par.
Defines an additional speed error step given to the input of the
speed controller (and added to the speed error value). This
can be used in large drive systems for dynamic speed
normalizing.
WARNING!
Make sure the error step value is removed
when a stop command is given.
0.00 rpm
-3000.00 …
3000.00 rpm
Speed error step.

Torque reference
speed control
Displays the speed controller output that is transferred to the
torque controller. See the control chain diagram on page
.
This parameter is read-only.
