310 Parameters
99.16 Motor phase order Switches the rotation direction of 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.
Notes:
• 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.
• 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 90.01 Motor speed for
control to 90.10 Encoder 1 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.
• This parameter cannot be changed while the drive is
running.
