DescriptionName / Range /
Selection
No.
No filtering / uint16(Visible when 92.1 Encoder 1 type = HTL)
Enables pulse edge filtering. Pulse edge filtering can
improve the reliability of measurements especially from
encoders with a single-ended connection.
Note: Pulse edge filtering is only supported by FEN-31
modules with FPGA version VIE3 2200 or later.
Note: Pulse edge filtering decreases the maximum
pulse frequency. With 2 µs filtering time, the maximum
pulse frequency is 200 kHz.

Selects the serial link mode with an EnDat or SSI
encoder.

0Single position transfer mode (initial position).Initial position
1Continuous position data transfer mode.Continuous
2Continuous speed and position data transfer mode.
This setting is intended for EnDat 2.2 encoders without
sin/cos signals.
Note: This setting requires an FEN-11 interface revision
H or later.
Continuous speed
and position
50 ms / uint16(Visible when 92.1 Encoder 1 type = Absolute encoder)
Selects the maximum encoder calculation time for an
EnDat encoder.
Note: This parameter needs to be set only when an
EnDat encoder is used in continuous mode, ie. without
incremental sin/cos signals (supported only as encoder
1). See also parameter 92.30 Serial link mode.

Selects the transmission cycle for an SSI encoder.
Note: This parameter needs to be set only when an SSI
encoder is used in continuous mode, ie. without
incremental sin/cos signals (supported only as encoder
1). See also parameter 92.30 Serial link mode.
