Siemens SINAMICS V90 Operating Instructions Manual page 297

Par. No. Name
Description: Position loop gain.
Two position loop gains in total are available. You can switch between these two gains by configuring the
digital input signal G-CHANGE or setting relevant condition parameters.
The first position loop gain is the default setting.
Dependency: The parameter value will be set to default after configuring a new motor ID (p29000).
p29111 Speed Pre-control Factor
(Feed Forward)
Description: Setting to activate and weight the speed pre-control value. Value = 0 % --> The pre-control is de-
activated.
p29120[0.. Speed Loop Gain
.1] **
Description: Speed loop gain.
Two speed loop gains in total are available. You can switch between these two gains by configuring the digital
input signal G-CHANGE or setting relevant condition parameters.
The first speed loop gain is the default setting.
Dependency: The parameter value will be set to default after configuring a new motor ID (p29000).
p29121[0.. Speed Loop Integral time
.1] *
Description: Speed loop integral time.
Two speed loop integral time values in total are available. You can switch between these two time values by
configuring the digital input signal G-CHANGE or setting relevant condition parameters.
The first speed loop integral time is the default setting.
Dependency: The parameter value will be set to default after configuring a new motor ID (p29000).
p29130 Gain Switching: Mode
Selection
Description: Selects gain switching mode.
0: Disabled
•
1: Switch through DI-G-CHANG
•
2: Position deviation as switch condition
•
3: Pulse input frequency as switch condition
•
4: Actual speed as switch condition
•
Note: Only when the auto tuning function (p20021=0) is disabled can the gain switching function be used.
p29131 Gain Switching Condition:
Pulse Deviation
Description: Triggers position deviation threshold for gain switching. If the gain switching function is enabled
and this condition is selected:
Switch from the first group of control parameters to the second group when the position deviation is larger
•
than the threshold.
Switch from the second group of control parameters to the first group when the position deviation is small-
•
er than the threshold.
