Code
Name
Causes
Possible Solutions
A fault occurred on the
machine.
Example: The machine is
locked.
Examine the machine and remove the
cause of the fault
The motor has overheated.
•
Check the load level, acceleration/
deceleration time, and motor start/stop
frequency (cycle time).
•
Decrease the load.
•
Increase the values set in
C1-01 to
C1-08 [Acceleration/Deceleration
Times]
.
•
Set
E2-01 [Motor Rated Current
(FLA)]
correctly to the value specified
by the motor nameplate.
•
Make sure that the motor cooling
system is operating correctly, and
repair or replace it if it is damaged.
•
Adjust
E1-04 to E1-10 [V/f Pattern
Parameters]
. For motor 2, adjust
E3-
04 to E3-10
. Decrease the values set
in
E1-08 [Mid Point A Voltage]
and
E1-10 [Minimum Output Voltage]
.
Note:
If the values set in
E1-08
and
E1-10
are too low, the overload tolerance
will decrease at low speeds.
