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.

413 [Encoder PPR]
Contains the encoder pulses per
revolution. For improved operation in FVC
Vector mode, PPR should be
≥
(64 x
motor poles).
Default:

1 PPR
414 [Enc Pos Feedback]
Displays raw encoder pulse count. For
single channel encoders, this count will
increase (per rev.) by the amount in
[Encoder PPR]. For quadrature encoders
this count will increase by 4 times the
amount defined in [Encoder PPR].
