Volts per Hertz
072 [Break Frequency]
Sets the [Break Voltage] output frequency of
the drive.
Refer to parameter 083 [Overspeed Limit].

Speed Feedback
412 [Motor Fdbk Type]
Selects the encoder type; single channel or
quadrature. Options 1 and 3 detect a loss of
encoder signal (when you are 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
can be ≥ (64 x motor poles).
Default:
Min/Max:
Units:
1024 PPR

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

415 [Encoder Speed]
Provides a monitoring point that reflects speed
as seen from the feedback device.

416 [Fdbk Filter Sel]
Selects the type of feedback filter desired.
“Light” uses a 35/49 radian feedback filter.
“Heavy” uses a 20/40 radian feedback filter.
