404 Parameters
92.14 Revolution data
width
(Visible when an absolute encoder is selected)
Defines the number of bits used in revolution counting with a
multiturn encoder. For example, a setting of 12 bits would
support counting up to 4096 revolutions.
The value is used when parameter 92.11 Absolute position
source is set to EnDat, Hiperface or SSI. When parameter
92.11 Absolute position source is set to Tamagawa, setting
this parameter to a non-zero value activates multiturn data
requesting.
Note: With an EnDat or HIPERFACE encoder and FEN-11
FPGA version VIE12200 or later, this parameter is
automatically set upon validation of encoder settings (91.10
Encoder parameter refresh).
0
0…32 Number of bits used in revolution count. 1 = 1
92.15 Transient filter (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).
4880 Hz
4880 Hz Change in direction of rotation allowed below 4880 Hz. 0
2440 Hz Change in direction of rotation allowed below 2440 Hz. 1
1220 Hz Change in direction of rotation allowed below 1220 Hz. 2
Disabled Change in direction of rotation allowed at any pulse frequency. 3
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.
A, B
A, B A and B. 0
A, B, Z A, B and Z. 1
A+, A-, B+, B- A+, A-, B+ and B-. 2
A+, A-, B+, B-, Z+,
Z-
A+, A-, B+, B-, Z+ and Z-. 3
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
