Description
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

(Visible when 92.1 Encoder 1 type
Defines the number of bits used to indicate position
within one revolution. For example, a setting of 15 bits
corresponds to 32768 positions per revolution.
The value is used when parameter
position source is set to EnDat,
parameter 92.11 Absolute position source
Tamagawa, this parameter is internally set to 17.
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
(91.10 Encoder parameter
Number of bits used in position indication within one
revolution.
(Visible when 92.1 Encoder 1 type
Selects whether position estimation is used with
encoder 1 to increase position data resolution or not.
Measured position used. (The resolution is 4 × pulses
per revolution for quadrature encoders, 2 × pulses per
revolution for single-track encoders.)
