Issue Number: 7
Spin Start Boost
(Pr
69
) is used by the algorithm that detects the frequency of a spinning motor when
the drive is enabled and
Catch A Spinning Motor
(Pr
33
)
≥
1. For smaller motors the default value of
1.0 is suitable, but for larger motors,
Spin Start Boost
(Pr
69
) may need to be increased.
If
Spin Start Boost
(Pr
69
) is too small the drive will detect zero frequency, whatever the frequency of
the motor, and if
Spin Start Boost
(Pr
69
) is too large, the motor may accelerate away from standstill
when the drive is enabled.
This parameter is the output of the PID controller. For further information, refer to the
Parameter
Reference Guide.
Proportional gain applied to the PID error. For further information, refer to the
Parameter Reference
Guide.
Integral gain applied to the PID error. For further information, refer to the
Parameter Reference
Guide.
This parameter allows the PID feedback source to be inverted. For further information, refer to the
Parameter Reference Guide.
