Selects which encoder cable channels and wires are
monitored for wiring faults.

(Visible when parameter
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.
Maximum pulse waiting time.
(Visible when parameter
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
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.
