Positioning module IMD20, IMD40
CanOpen protocol
Device profile parameters
CanOpen comprises different devices (e.g. I/O modules, drives, encoders ...), so-called device
profiles, in which pre-defined parameters and modes of operation are available for each device class.
According to the functional scope of a device, more or less of these default objects can be
according to functional groups. In this regard, all drive functions and the
Dev
implemented.
The drive module uses the DS402 V1.0 device module. In the following, all used parameters are
listed and described
behaviour of the module are shown in the different modes of operation.
ice control
The drive module comprises a so-called state machine which defines which operating states may be
applied and how the transition to other states can be triggered. This status diagram is controlled by a
Control word or by an event (e.g. errors that occurred). Via the status word the current state can be
queried.
