LED status Operating state Description
-Off Not ready No line voltage
→ Check supply cable and line voltage for interruption.
Yellow Flashing
steadily
Not ready Initialization phase
Green Flashing
steadily
Not ready Power section parameters are being loaded or firmware is being updated
Green Steady light Ready for
operation
System ready
Yellow Steady light Ready but unit
inhibited
"STO" signal detected, safe stop
→ Check voltage at STO terminal
Green/
yellow
With alter-
nating
colors
Ready but timeout Cyclical data exchange – communication interrupted (error 47 or 67).
→ No SBus/SNI connection between DRC inverter and controller. Check and estab-
lish connection, especially terminating resistor.
→ EMC influence Check shielding of data lines and improve, if necessary.
→ Protocol time between the individual telegrams is longer than the set time (timeout
interval). Shorten telegram cycle.
Red Steady light Error Possible errors:
• CPU error (17, 37)
• NV memory error (25)
• Error while transmitting parameters (97)
• IPOS error (10)
• Boot synchronization error (40, 41)
• Safety error (119)
→ More detailed diagnostic information via Drive LED.
