1553 VOLTAGE STABILATOR LIMIT 6 (2.6.26.11)
Use this parameter to set the limits for the voltage stabilizer output.
This parameter sets the limits for the voltage stabilizer output i.e. the max. and the min.
value for the correction term df in FreqScale.
1566 POLARITY PULSE CURRENT 6 (P2.6.24.5)
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 P2.6.24.4. Polarity direction check is seldom
needed because the identification itself gives already the right direction. Hence in most
cases, this function can be disabled by setting any negative parameter value, which is
recommended especially if there occurs F1 faults during the identification.
1587 INV DELAYED DO1 6 (P2.3.1.5)
Use this parameter to invert the delayed digital output signal.
Inverts delayed digital output signal 1.
1588 INV DELAYED DO2 6 (P2.3.2.5)
Use this parameter to invert the delayed digital output signal.
Inverts delayed digital output signal 2.
1691 START ANGLE ID MODIFIED 6 (P2.6.24.3)
Use this parameter to select the start angle identification when no absolute encoder or
incremental encoder with zpulse are used.
Identification for the start angle, i.e. the rotor magnet axis position in respect to the stator U-
phase magnet axis, is needed if no absolute encoder or incremental encoder with zpulse 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.
In case of absolute encoders, the start angle reads the angle value directly from the encoder.
On the other hand, incremental encoder z-pulse is used automatically for synchronization if
its position is defined different from zero in P2.6.24.2. Also for absolute encoders, P2.6.24.2
must be different from zero, otherwise it is interpreted that the encoder identification run
has not been done and the running will be prohibited except if the absolute channel is
bypassed by the start angle identification.
NOTE!
ModulatorType (P2.4.20) needs to be > 0 to be able to use this function.
