Float IM T, U
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).

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
0 4 0 - I16 IM T
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
0 214748364
7
100 LU I32 IM T
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.
