p1476[0...n] BI: Speed controller hold integrator / n_ctrl integ stop
Access level: 4
Can be changed: T
Units group: -
Min
-
Description: Sets the signal source to hold the integrator for the speed controller.
p1477[0...n] BI: Speed controller set integrator value / n_ctrl integ set
Access level: 3
Can be changed: T
Units group: -
Min
-
Description: Sets the signal source to set the integrator setting value (p1478).
Dependency: Refer to: p1478, p1479
Notice: The parameter may be protected as a result of p0922 or p2079 and cannot be changed.
p1478[0...n] CI: Speed controller integrator setting value / n_ctr integ_setVal
Access level: 3
Can be changed: T
Units group: -
Min
-
Description: Sets the signal source for the integrator setting value for the velocity controller.
The signal to set this integrator setting value is interconnected via p1477.
Dependency: The setting value of the speed controller integrator is weighted with the scaling factor of the signal source in p1479.
If p1478 is interconnected to the integral output of the speed controller (r1482), then after the magnetizing time
(r0346) and if the speed controller is enabled, the integral component of the controller is set to the last value before
the pulse inhibit. This value is set if no setting command (p1477) is interconnected or, at the instant that the pulses
were inhibited, a setting command is available, which is not de-activated up to the next time that the pulses are
inhibited. For sensorless vector control, in addition p1400.1 should be set to 1 so that when the drive is stopped, the
integral component of the speed controller is not controlled down to zero.
In order that when setting the integrator output, only the static torque is detected, we recommend that the accelerat-
ing torque is completely pre-controlled (e.g. p1496).
If p1478 is interconnected to another output other than r1482, then after magnetizing and speed controller enable,
the integral output is set once if the setting command is not interconnected (p1477 = 0).
Refer to: p1477, p1479
Notice: The parameter may be protected as a result of p0922 or p2079 and cannot be changed.
p1479[0...n] CI: Speed controller integrator setting value scaling / n_ctrl I_val scal
Access level: 4
Can be changed: T
Units group: -
Min
-
Description: Sets the signal source for scaling the integrator setting value (p1478) of the speed controller.
Dependency: Refer to: p1477, p1478
