emergency stop
1. If the inverter is set to external control mode (b000 = 0001), and the
Stop key is pressed (A010 = 0000), the inverter will stop based on the
setting of B003 and STP2 will flash. Turn the run switch to OFF and
then ON again to restart the inverter.
2. If the inverter is in communication mode and the Stop key is pressed
(A010 = 0000), the inverter will stop based on the setting of b003 and
STP2 will flash. The PLC or PC must send a Stop command then a
Run command to the inverter for it to be restarted.
3. The Stop key cannot perform an emergency stop when
A010 = 0001.
E.S.
External
emergency stop
The inverter will decelerate to stop and flashes E.S., when there
is an external emergency stop signal via the Control input terminals.
(See parameters A050-A056).
b.b..
External
base block
The inverter stops immediately (motor coasts to stop) and then
flashes b.b., when external base block is input through the multi-
functional input terminal. (See parameters A050 - A056).
ATER
Auto-tuning faults
1. Motor data error resulting in auto-tuning failure.
2. Stopping the inverter during Auto-tuning before completion.

modifications
locked out
1. Attempt to modify frequency
parameter while A039 > 0000.
2. Attempt to reverse while
b002 = 0001.
1. Set A039 = 0000.
2. Set b002 = 0000.
Err1
Keypad
operation error
1. Attempt to p
ress ▲ or ▼keys
when b004 > 0 or in speed
operation.
2. Attempt to modify parameters, which
can not be modified during Run.
(see parameter list)
1. The ▲ or▼ is available
for modifying the
parameter only when
b004=0.
2. Modify the parameters
only in stop mode.
Err2
Parameter setting
error
1. The setting of b006 is within ranges
of parameters A032 ± A035 or A033
± A035 or A034 ± A035.
2. b005
≤ b006.
3. Setting error while performing Auto
tuning. (e.g. b000
≠ 0, b004 ≠ 0 )
1. Modify A032-A034 or A035.
2. b005 > b006.
3. Set b000 = 0, b004 = 0
during
Auto tuning.
Err5
Modification of
parameter is
not allowed
during
communication
1. 1. Enable command disabled during
communication.
2. Modify parameters A164 -167
during communication.
1. Issue enable command
before / while
Communicating.
2. Set parameters 164-167
before communicating.
