Parameters 213
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 these terms (parameters
) are
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.
-
-1600.0…1600.0%
Limited speed controller output torque.
See par.
