Gain for flux circle stabilizer (0–32766).
10.511 (ID 1551) Flux Stabilator TC
Location in the menu:
P2.6.18.6
(Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to set the filter coefficient of the identification current stabilizer.
10.512 (ID 1552) Voltage Stabilator TC
Location in the menu:
P2.6.18.10
(Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to set the damping rate of the voltage stabilizer.
Damping rate of voltage stabilizer (0–1000).
10.513 (ID 1553) Voltage Stabilator Limit
Location in the menu:
P2.6.18.11
(Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to set the limits for the voltage stabilizer output.
This parameter sets the limits for the voltage stabilizer output that is, the maximum and the minimum value for the correction term
df in FreqScale.
10.514 (ID 1566) Polarity Pulse Current
Location in the menu:
P2.6.16.5
(Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to set the current level for the polarity direction check of the magnet axis during the start angle identification.
Value 0 means that the internal current level is used, which is typically slightly higher than the normal identification current defined
by
ID 1756
. Polarity direction check is seldom needed because the identification itself already gives the right direction. Hence usual-
ly, this function can be disabled by setting any negative parameter value, which is recommended especially when there are F1 faults
during the identification.
10.515 (ID 1587) Invert Delayed DO1
Location in the menu:
P2.3.1.5
(Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to invert the delayed digital output signal.
Inverts delayed digital output signal 1.
10.516 (ID 1588) Invert Delayed DO2
Location in the menu:
P2.3.2.5
(Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to invert the delayed digital output signal.
Inverts delayed digital output signal 2.
10.517 (ID 1691) Start Angle ID Modified
Location in the menu:
P2.6.16.3
(Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to select the start angle identification when no absolute encoder or incremental encoder with z-pulse are used.
Identification for the start angle, that is, the rotor magnet axis position in respect to the stator U-phase magnet axis, is needed when
no absolute encoder or incremental encoder with z-pulse are used. This function defines how the start angle identification is made
in those cases. The identification time depends on the motor electrical characteristics but takes typically 50 ms-200 ms.
With absolute encoders, the start angle reads the angle value directly from the encoder. However, incremental encoder z-pulse is
used automatically for synchronization when its position is defined different from zero in
ID 649
. Also for absolute encoders,
ID 649
must be different from zero. Otherwise it is interpreted that the encoder identification run has not been done and the running is
prohibited except when the start angle identification bypasses the absolute channel.
ModulatorType (
ID 1516
) has to be > 0 to be able to use this function.
