CAN Interfaces of MOVIDRIVE® B
The unit states can be changed at any time using NMT services. Possible commands:
• Node_Start indication [6]
• Node_Stop indication [7]
• Enter_Pre-Operational_State indication [8]
• Reset_Node indication [10]
This command is used to reset the entire inverter. This means an inverter fault is
acknowledged and the default settings in the object directory and the CANopen
communication range (0x1000 to 0x1FFF) become active.
• Reset_Communication [11]
This command causes the communication parameters in the object directory to be
reset (index 0x1000 to 0x1FFF).
• Initialization finished [12]
The node automatically changes to "pre-operational" and sends a guarding telegram
( slave ID) as "boot-up" message.
The CAN telegrams are structured as follows:
The node ID corresponds with the address set in parameter P886/896. The value "0" is
permitted for the node ID. In this case, all CANopen devices will be addressed.
NMT services are not acknowledged by the slave.
MOVIDRIVE
®
B supports the so-called "Minimum Capability Device", i.e. the following
states are supported:
• Pre-operational
In "pre-operational" state, the device can only communicate via SDOs.
• Operational
In "operational" state, PDOs and SDOs can be exchanged.
• Stopped
In "stopped" state, neither PDOs nor SDOs can be exchanged.
When switching MOVIDRIVE
®
B back on, the CANopen interfaces are always automat-
ically in "pre-operational" state. After switching back on, they go to "operational" state if
index 0x27FA subindex 1 (SBus 1) or subindex 2 (SBus 2) is 1.
If MOVIDRIVE
®
B remains in "booting" state after switching it on again, no boot-up
message could be sent. This means no other CAN unit can be accessed via SBus.
Check the connection and parameter setting of all unit on CAN.
