Parameters 405
92.24 Pulse edge filtering (Visible when parameter 92.01 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.
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.
No filtering
No filtering Filtering disabled. 0
1 µs Filtering time: 1 microsecond. 1
2 µs Filtering time: 2 microseconds. 2
92.25 Pulse
overfrequency
function (Visible when parameter 92.01 Encoder 1 type = HTL )
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.
Fault
Warning The drive generates a warning, 7381 Encoder . The FEN-xx
module will continue to update speed and position data.
0
Fault The drive trips on fault A7E1 Encoder . 1
92.30 Serial link mode (Visible when an absolute encoder is selected)
Selects the serial link mode with an EnDat or SSI encoder.
Initial position
Initial position Single position transfer mode (initial position). 0
Continuous Continuous position data transfer mode. 1
Continuous speed
and position 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.
2
92.31 EnDat max
calculation time (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
parameter
92.30 Serial link mode .
50 ms
10 us 10 microseconds. 0
100 us 100 microseconds. 1
1 ms 1 millisecond. 2
50 ms 50 milliseconds. 3
92.32 SSI cycle time (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
parameter
92.30 Serial link mode .
