keys when
A01 > 0 or in speed
operation.
2. Attempt to modify
parameters, which cannot
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
2. A02 < A03
1. Change A02 value
2. Make A02 > A03
Modification of
parameter is not
allowed during
communication
1. Control command given
when communications are
disabled
2. Attempt to modify b77 ~
b81 during communication.
Set up parameters before
communication begins.
Communication
failure
1. Incorrect cabling.
2. Incorrect settings of
communication parameters.
3. Check sum error.
4. Incorrect communication
program.
1. Check connections.
2. Check b77 ~ b81
Incorrect
parameter
settings
1. Attempt to modify b89
2. Voltage and current
detection circuits work
abnormally.
1. Reset
iDrive.
2. If not possible
contact your supplier
Parameter set
error, Copy Unit
failure
1. If b94 = 1 or 2, and cannot
connect with Copy Unit.
2. Copy Unit failure.
3. The voltage and capacity
parameter of Copy Unit &
the
iDrive
are different.
1. Modify b94
2. Change Copy Unit
3. Copy the same
iDrive
parameter for voltage and
capacity, then WRITE.
Parameters do
not match
When copying parameters
to
iDrive
– verification
code that parameters do
not match.
1. Change Copy Unit
2. The voltage and capacity
parameter in Copy Unit
are different to
iDrive
