12.9.6 Diagnoscs
12.9.6.1 LED status display
Informaon about the CAN bus status can be obtained quickly via the "CAN-RUN" and "CAN-
ERR" LED displays on the front of the inverter.
The meaning can be seen from the tables below.

The green "CAN-RUN" LED indicates the CANopen state:
LED "CAN-RUN" CANopen state
blinking fast (5 Hz)

Operaonal
blinking 1x, then goes o for 1 s
Stopped
The red "CAN-ERR" LED indicates a CANopen error:
LED "CAN-ERR" CANopen error
blinking 1x, then goes o for 1 s
Warning Limit reached
blinking 2x, then goes o for 1 s
Heartbeat Event
blinking 3x, then goes o for 1 s
Sync message error (only possible in the "Operaonal" state)
12.9.6.2 Informaon on the network
The inverter has various diagnosc parameters for displaying ...
•
the acve node address, baud rate and current DIP switch sengs;
•
the network status, the CAN master status and the status of various me monitors;
•
telegram counters.
The telegram counters are free-running, i. e. aer reaching the maximum value , the respec-
ve counter starts again at 0.
The following parameters show informaon on the network.
Parameter

0x1001 Error register
•
Read only
Bit-coded error status.
•
Bit 0 is set if an error is acve.
The other bits signalise which group the acve error belongs to:
•
Bit 1: Current error
•
Bit 2: Voltage error
•
Bit 3: Temperature error
•
Bit 4: Communicaon error
•
Bit 5: Device prole-specic error
•
Bit 6: Reserved (always 0)
•
Bit 7: Manufacturer-specic error
