Description
Calculated number of pole pairs in the motor.
This parameter is read-only.
Number of pole pairs.
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
selection to Estimate, and comparing the sign of
Motor speed for control
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
Note: This parameter cannot be changed while the
drive is running.
