Description
(Visible when a TTL, TTL+ or HTL encoder is selected)
Activates transient filtering for the encoder (changes in
direction of rotation are ignored above the selected pulse
frequency).
Change in direction of rotation allowed below 4880 Hz.
Change in direction of rotation allowed below 2440 Hz.
Change in direction of rotation allowed below 1220 Hz.
Change in direction of rotation allowed at any pulse
frequency.
(Visible when parameter
HTL 2)
Selects the power supply voltage for encoder 1.
Disabled.

(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.
