069 [Start/Acc Boost]
Sets the voltage boost level for starting and
acceleration when “Custom V/Hz” mode is
selected. Refer to parameter 083 [Overspeed
Limit].

412 [Motor Fdbk Type]
Selects the encoder type; single channel or
quadrature. Options 1 & 3 detect a loss of
encoder signal (when using differential inputs)
regardless of the [Feedback Select], param. 080
setting. For FVC Vector mode, use a quadrature
encoder only (option 0/1). If a single channel
encoder is used (option 2/3) in sensorless vector
or V/Hz mode, select “Reverse Dis” (option 2) in
param. 190.
