MOTOR CONTROL
Volts per Hertz
071 [Break Voltage]
Sets the voltage the drive will output at
[Break Frequency]. Refer to parameter
083 [Overspeed Limit].

072 [Break Frequency]
Sets the frequency the drive will output at
[Break Voltage]. Refer to parameter 083.
Default:

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.

“Single Check”
413 [Encoder PPR]
Contains the encoder pulses per
revolution. For improved operation in
FVC Vector mode, PPR should be ≥ (64
x motor poles).
Default:
Min/Max:
Units:
1024 PPR
2/20000 PPR
1 PPR
414 [Enc Position Fdbk]
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].
Default:
Min/Max:

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

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.
Default:

419 [Notch Filter Freq]
Sets the center frequency for an optional
2-pole notch filter. Filter is applied to the
torque command. “0” disables this filter.
Default:
Min/Max:
Units:
