„ Minor Faults and Alarms
Digital Operator Display Fault Name
oFb00
Non-Compatible Option connected to drive port CN5-B
Non-compatible option is connected.
Cause Possible Solution
Non-compatible option connected to
drive port CN5-B. Use only compatible options. Connect the SI-P3 to CN5-A. For other option connections, refer to the
Installation Manual for those options.
Digital Operator Display Fault Name
oFb02
Option Fault (CN5-B)
Two of the same option are connected simultaneously.
Cause Possible Solution
Options AI-A3 or D1-A3 connected to
the CN5-B port while an option was
connected to CN5-A.
Only one of these options, AI-A3, DI-A3 or SI- †† option can be connected to the drive at the same time.
The SI-N3 must be connected to CN5-A.
Digital Operator Display Fault Name
oFc00
Non-Compatible Option connected to drive port CN5-C
Non-compatible option is connected.
Cause Possible Solution
Non-compatible option connected to
drive port CN5-C. Use only compatible options. Connect the SI-P3 to CN5-A. For other option connections, refer to the
Installation Manual for those options.
Digital Operator Display Fault Name
oFc02
Option Fault (CN5-C)
Two of the same options are connected simultaneously.
Cause Possible Solution
Options AI-A3 or D1-A3 connected to
the CN5-C port while an option was
connected to CN5-A.
Only one of these options, AI-A3, DI-A3 or SI- †† option can be connected to the drive at the same time.
The SI-N3 must be connected to CN5-A.
Digital Operator Display Minor Fault Name
bb
Baseblock
Data format and setting contents do not match.
Cause Possible Solution
Minor Fault
(H2- = 10)
The drive output is disabled.
“bb” is displayed on the operator when the
drive is set for control by PROFIBUS-DP,
and a conventional data format is used,
and the operation command bit F is set to 1,
or a PPO type data format is used,
and the control word (STW) bit 3 is set to 0.
Set either of the bits depending on the data format used. No output
Digital Operator Display Minor Fault Name
CALL
Serial Communication Transmission Error
Communication has not yet been established.
Cause Possible Solution
Minor Fault
(H2- = 10)
Communication wiring or terminal resistor
connection is faulty. There is a short circuit, or
an option component is not connected
properly.
Check for wiring errors and correct the wiring.
Remove any ground shorts and reconnect loose wires.
Yes
Master-side programming error. Check communications at start-up and correct programming errors.
Damaged communication circuitry.
Perform a self-diagnostics check and replace the drive if the fault
continues to occur.
