Selection No.
0 / uint16 Calculated number of pole pairs in the motor.
This parameter is read-only. Motor polepairs
calculated 99.15
1 = 1 / 1 = 1 Number of pole pairs. 0...1000
U V W / uint16 Switches the rotation direction of the motor. This
parameter can be used if the motor turns in the wrong
direction (for example, because of the wrong phase
order in the motor cable), and correcting the cabling
is considered impractical.
Note: Changing this parameter does not affect speed
reference polarities, so positive speed reference will
rotate the motor forward. The phase order selection
just ensures that "forward" is in fact the correct
direction.
Note: After changing this parameter, the sign of
encoder feedback (if any) must be checked. This can
be done by setting parameter
90.41 Motor feedback
selection to Estimate , and comparing the sign of 90.1
Motor speed for control to 90.10 Encoder 1 speed (or
90.20 Encoder 2 speed ). If the sign of the measurement
is incorrect, the encoder wiring must be corrected or
the sign of
90.43 Motor gear numerator reversed.
Note: This parameter cannot be changed while the
drive is running.
Motor phase order 99.16
0 Normal. U V W
1 Reversed rotation direction. U W V
0.000 mH / real32 Defines the inductance of a custom sine filter, i.e. when
parameter
95.15 Special HW settings bit 3 is activated.
Note: For an ABB sine filter ( 95.15 Special HW settings
bit 1), this parameter is set automatically and should
not be adjusted.
