92.17 Accepted pulse freq
of encoder 1
(Visible when parameter 92.01 Encoder 1 type = HTL 1 or
HTL 2)
Defines the maximum pulse frequency of encoder 1.
0 kHz
0…300 kHz Pulse frequency. 1 = 1 kHz
92.21 Encoder cable fault
mode
(Visible when a TTL, TTL+ or HTL encoder is selected)
Selects which encoder cable channels and wires are
monitored for wiring faults.

92.23 Maximum pulse
waiting time
(Visible when parameter 92.01 Encoder 1 type = TTL or HTL)
Determines a pulse waiting time used in speed calculation for
the encoder interface. If no pulse edges are detected within
this time, the measured speed is zeroed by the interface.
Increasing the setting can improve measuring performance
especially at low, near zero speeds.
Notes:
• The parameter is only supported by FEN-xx modules with
FPGA version VIEx 2000 or later. On older modules, the
pulse waiting time is fixed to 4 ms.
• The parameter only affects speed measurement. Position
is updated whenever a new pulse edge is detected. When
the measured speed from the interface is zero, the drive
updates its speed data based on position changes.
4 ms
1…200 ms Maximum pulse waiting time. 1 = 1 ms
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.
