Possible Solution
3. Multi-function input
wiring is not correct
2. Confirm if the signal lines is
properly connected to the
terminals assigned for external
fault detection (E1-口口= 23 to
38)
3. Confirm if E1-口口=23 to 38 is
set to the unused terminals.
oH
Heatsink Overheat
Heatsink temperature
over 90 to 100°C
(Overheat level is
determined by rating of
the drive)
1. Ambient temperature is
too high
2. Internal cooling fan
stopped operating
3. Bad air flow due to
insufficient room.
1. Check the temperature
surrounding the drive
a. Improve the air flow inside the
enclosure panel
b. Install an air conditioner or fan
to cool the environment
c. Remove any possible source of
heat
2. Measure the output current
a. Reduce the load
b. Lower setting in C6-00
( Carrier Frequency Option )
3.Replace the cooling fan
oH1
Motor Overheat
The temperature signal
from motor
temperature sensor via
the terminal MT
exceeded the overheat
detection level of the
drive.
1. Incorrect motor
temperature input (terminal
MT) wiring
2. Fault on the machinery
(e.g., machinery is locked
up)
3. Motor overheat
1. Correct the wiring for terminal
MT.
2. Check the machinery status
3. Check the load, acceleration /
deceleration time and cycle time
a. Reduce the load.
b. Increase C1-00 to C1-07
(Acc./Dec. Time) settings
c. Adjust d1-02 to d1-11 (V/F
Characteristics)
oL
Mechanical Weakening
Detection for
Overtorque
Overtorque in the
conditions set to P6-06
Overtorque in the
conditions set to P6-06
Check the condition of
mechanical weakening
oL1
Motor Overload
1. The load is too heavy
2. The acceleration and
deceleration times are too
short
3. The motor is driven
1. Check loading capacity
» Reduce the load
2. Confirm acceleration and
deceleration times
»Increase C1-00 to C1-07
