Description
(Visible when parameter 92.01 Encoder 1 type
Enables pulse edge filtering. Pulse edge filtering can improve
the reliability of measurements especially from encoders with
a single-ended connection.
Notes:
• Pulse edge filtering is only supported by FEN-31 modules
with FPGA version VIE3 2200 or later.
• Pulse edge filtering decreases the maximum pulse
frequency. With 2 µs filtering time, the maximum pulse
frequency is 200 kHz.
Filtering disabled.
Filtering time: 1 microsecond.
Filtering time: 2 microseconds.
(Visible when parameter 92.01 Encoder 1 type
Selects how the drive reacts when the encoder interface
detects a pulse overfrequency condition.
Note: This parameter is effective only with FEN-xx module
FPGA version VIEx 2200 or later.
The drive generates a warning,
module will continue to update speed and position data.
The drive trips on fault A7E1
(Visible when an absolute encoder is selected)
Selects the serial link mode with an EnDat or SSI encoder.
Single position transfer mode (initial position).
Continuous position data transfer mode.
Continuous 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.
(Visible when an absolute encoder is selected)
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

(Visible when an absolute encoder is selected)
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
