Description
(Visible when a resolver is selected)
Defines the frequency of the excitation signal.
Note: With an EnDat or HIPERFACE encoder and FEN-11
FPGA version VIE12200 or later, this parameter is
automatically set upon validation of encoder settings
Encoder parameter refresh).
Excitation signal frequency.
(Visible when a TTL, TTL+ or HTL encoder is selected)
Selects the type of encoder.
Quadrature encoder (with two channels, A and B)
Single-track encoder (with one channel, A).
Note: With this setting, the measured speed value is always
positive regardless of direction of rotation.
(Visible when an absolute encoder is selected)
Selects the source of the absolute position information.
Not selected.
Commutation signals.
Serial interface: EnDat encoder.
Serial interface: HIPERFACE encoder.
Serial interface: SSI encoder.
Serial interface: Tamagawa 17/33-bit encoder.
(Visible when a resolver is selected)
Defines the rms amplitude of the excitation signal.
Excitation signal amplitude.
(Visible when a TTL, TTL+ or HTL encoder is selected)
Selects the speed calculation mode.
*With a single-track encoder (parameter
type is set to Single track), the speed is always positive.
Channels A and B: Rising and falling edges are used for
speed calculation.
*Channel B: Defines the direction of rotation.
Note: With a single-track encoder (parameter
encoder type), this setting acts like setting
Channel A: Rising and falling edges are used for speed
calculation.
*Channel B: Defines the direction of rotation.
Channel A: Rising edges are used for speed calculation.
*Channel B: Defines the direction of rotation.
Channel A: Falling edges are used for speed calculation.
*Channel B: Defines the direction of rotation.
One of the above modes is selected automatically depending
on the pulse frequency as follows:
Pulse frequency of the
channel(s)
< 2442 Hz
2442...4884 Hz
> 4884 Hz
