13. Trip information and measures
English
STO activated 1) Open state between [STOA]/[STOB] and
[PLC] terminal.
2) 24V output terminal [PLC]/[P24] overload.
3) SW1 is set on "PLC" position and an
external power is not supplied.
Communication Condition very close to the communication
alarm time out trip.
(RS485, option)
Brake learning error 1) The load is heavy.
2) Parameter setting is improper.
3) Braking operation is abnormal.
Light-load high- Setting of the motor parameter is improper.
speed learning error
English
Overcurrent pre- Condition close to the overcurrent trip.
alarm
Overheat pre-alarm Condition close to the overheat trip.
Motor overload pre- Condition close to the overload trip.
alarm
Overvoltage pre- Condition close to the overvoltage trip.

English
V/f 5-point setting When <Pt:V/f Pattern> = "7: V/f 5-point
error 1 setting", two or more from <vL>, <F190>,
<F192>, <F194>, <F196> and <F198> are
set to the same value other than 0.0 Hz.
V/f 5-point setting Inclination of V/f is large.
error 2
Base frequency Tries to run in frequency over 10 times of the
setting error base frequency.
Setting for Asia Setting for Asia is selected in the setup
menu.
During auto tuning Auto-tuning in progress.

Measures
1) Short circuit [STOA] - [STOB] - [PLC]. (By
default, short circuit is done with a shorting
bar).
2) Check 24V load.
3) Check SW1 position and external power
supply.
Perform the same measures with
communication time out "Err5" and "Err8".
1) Perform learning with no load or light load
in approx. 3 % or less rating.
2) Set the motor parameters and learning
related parameters in advance.
3) Check the brake.
Set the motor parameters according to the
motor.
Measures
Perform the same measures with overcurrent
"OC1", "OC2", and "OC3".
Perform the same measures with overheat
"OH".
Perform the same measures with overload
"OL1", "OL2", and "OL3".
Perform the same measures with overvoltage
"OP1", "OP2", and "OP3".
Remarks
Set different value on each parameter.
• Set V/f 5-point and <vLv>/<vL> for the V/f
inclination to be gentle.
• Increase the value of <VL>, or decrease
the value of <VLV>.
• Check that the base frequency setting is
correct. <vL: Base frequency 1>, etc.
• Operate in frequency within 10 times of the
base frequency.
