error
1. Press▲ or ▼ keys when
A01 > 0 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 modify frequencies only
when A01 = 0.
2. Modify them after stop.
Parameter
setting error
1. A02 is in ranges of
b20±b22 or b21±b22
Er1
2. A02 < A03
1. Change A02 value
2. Make A02 > A03
Modification of
parameter is not
allowed during
communication
Er2
1. Control command given
when communications are
disabled
2. Attempt to modify b77 ~
b81 during communication.
Set up parameters before
communicating.
Communication
failure
1. Incorrect cabling.
2. Incorrect settings of
communication parameters.
3. Check sum error.
4. Incorrect communication
program.
Er5

Unit
failure
1. b94 = 1,2. Cannot connect
with Copy Unit.
2. Copy Unit failure.
Er7
3. The voltage and capacity
parameter of Copy Unit &
the inverter are different.
1.Modify b94
3. Change Copy Unit
4. Copy the same inverter
parameter for voltage and
capacity, then input.
EP1
Copy the parameter to
inverter to verify the
parameter is not match.
1. Change Copy Unit
Parameters do
not match
2. The voltage and capacity
parameter of Copy Unit
are different
