4.2.2.6 "CANopen Object Dictionary" Details

The following tables show the full object directory for the sensor. The first table shows the communication portion of the object
directory. Apart from a few exceptions, these settings correspond to the CANopen standard as described in DS 301. There are
some communication limitations based on the hardware platform used. The configuration steps for "heartbeat time" (Index
1017h), "TPDO1 event timer" (Index 1800h, Subindex 5), "TPDO2 event timer" (Index 1801h, Subindex 5), "TPDO3 event timer" (In-
dex 1802h, Subindex 5) are limited to 50 ms in place of the 1 ms envisaged. This means that these objects can be configured to
0 ms, 50 ms, 250 ms, but not 35 ms, 125 ms, etc.
