Cause
1. Press▲ or ▼ keys when
A01 > 0 or in speed
operation.
2. Attempt to modify
parameters, which cannot
be modified during Run
(see parameter list).
1. A02 is in ranges of
b20±b22 or b21±b22
2. A02 < A03
1. Control command given
when communications are
disabled
2. Attempt to modify b77 ~
b81 during communication.
1. Incorrect cabling.
2. Incorrect settings of
communication parameters.
3. Check sum error.
4. Incorrect communication
program.
1. Attempt to modify b89
2. Voltage and current
detection circuits work
abnormally.
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.
When copying parameters
to iDrive – verification
code that parameters do
not match.

Chapter 5 Trouble shooting and maintenance
1. ▲ or ▼ keys can be used
to modify frequencies only
when A01 = 0.
2. Modify them after Stop.
1. Change A02 value
2. Make A02 > A03
Set up parameters before
communication begins.
1. Check connections.
2. Check b77 ~ b81
1. Reset iDrive.
2. If not possible
contact your supplier
1. Modify b94
2. Change Copy Unit
3. Copy the same iDrive
parameter for voltage and
capacity, then WRITE.
1. Change Copy Unit
2. The voltage and capacity
parameter in Copy Unit
are different to iDrive
