External base block
The inverter stops immediately and then flashes b.b. when external
base block is input through the multi-functional input terminal (see
descriptions of F11-F14).
PID feedback signal loss
PID feedback signal circuit error detection
Remote keypad cable
broken
1. When REMOTE KEYPAD does not communicate with the inverter,
this signal will be displayed on the Main keypad.
2. When REMOTE KEYPAD connects improperly with inverter, this
signal will be displayed on the main keypad.
3. When both REMOTE KEYPAD and main KEYPAD display this signal,
communication errors result.

Error
Cause
Remedy
Key operation
error
1. Attempt to Press▲ or ▼ keys
when F05 ≠ 000 or in speed
operation.
2. Attempt to modify parameters,
which can not be modified during
Run (see parameter list).
1.
▲ or ▼ keys can be used to
control output frequency only
when F05=000.
2. Modify parameters only in
stop mode.
Parameter setting error
The setting of parameter F07 is
within ranges of Parameters C27 ±
C29 or C28 ± C29
F07<F08 or F07=F08
1. Modify Parameters C27- C29
2. F07>F08
Modification of parameter
is not allowed during
communication
1. Enable command disabled during
communication
2. Modifying parameters C49-C53
during communication.
1. Issue an enable command
before/while communicating.
2. Set up parameters before
communicating.
Communication failure
1. Faulty/Incorrect wiring.
2. Incorrect settings of communication
parameters
.
3. Check-sum error.
4. Incorrect communication
verification.
1.
1. Check hardware and wiring.
2. Check parameters
C49-C53
Incorrect parameter
settings
1. Attempt to change F00
2. Voltage and current detection
circuits are malfunctioning.
Reset inverter or contact
technical support
Parameter set error,
Copy unit failure
1. Can not connect with Copy unit.
2. Copy unit failure.
3. The voltage and inverter
rating on Copy unit & the
inverter are different.
1. Modify Parameter C48
2. Change Copy unit
3. Copy from keypad to
inverter with only
matched HP ratings.
Parameters do not match
Copy the parameter to
inverter to verify the
parameter not matched.
1. Change Copy unit
2.
The voltage and HP rating of
Copy unit is different than the
inverter.
