Mapping
The encoder supports a customer specific mapping for PGN65450, which can be specified, when ordering an encoder.
Mappable objects
7.3.1
The following objects are mappable:
Mapping content
Position encoder
Speed encoder [steps/sec]
Alarms
Warnings
Diagnostic
Speed [rpm]
Time Stamp
Default mapping of absolute encoder
7.3.2
Byte 0
Byte 1
Position[0]
Position[1]
Byte 0 – 3 Encoder absolute position:
Datatype: 4 Byte, U32,
Resolution: According to scaling factors (see encoder parametrization)
Byte 4 – 5 Encoder speed value:
Datatype: 2 Byte, S16,
Resolution: [rpm]
Byte 6 – 7 (Encoder diagnostic):
See Object description in chapter 0x2117 Encoder Diagnostics
7.4
Timing
The minimal cycle time for PGN65450 is 1 ms, although the J1939 suggest to use minimal cycle times of 50 ms.
7.5
Exceptions of accurate calculation of process data
The following operations could interrupt the accurate calculation of process data such as position, speed, warnings and
alarms:
-
Changing the scaling parameters
