12. CONT (control signal) Error
[Display]
[Description of detected alarm]
[Cause and remedy]
Cause Remedy
The same input signal is allocated to two or
more terminals.
Do not specify the same number among
CONT signal settings.
13. Overload
[Display]
[Description of detected alarm]
[Cause and remedy]
Cause Remedy
The servomotor fails to rotate
mechanically.
•
Check the wiring of power cables (U, V and
W) and correct faults.
•
Check if the brake is active.
The mechanical system is too heavy
against the servomotor capacity.
•
Examine the servomotor capacity, based on
the load factor.
•
If the rotation speed can be reduced, add a
reduction gear.
•
Apply the brake to retain a stopped
elevator.
The acceleration/deceleration frequency
and operation frequency are too high.
Increase the cycle time and decrease the
operation frequency.
Servo amplifier is damaged.
Replace the servo amplifier.
If an OL2 alarm is caused but no damaged servo amplifier or incorrect wiring is found, the
servomotor capacity must be examined.
Check the OL thermal value with the PC Loader or monitor mode of the keypad in both cases.
14. Main Power Undervoltage
[Display]
[Description of detected alarm]
There is duplication in allocation of sequence input terminals of
the servo amplifier.
OL1: Instantaneous alarm such as a locked shaft. (3s/300%)
OL2: The effective torque exceeds the allowable limit of the
servomotor. (Detection at electronic thermal relay built in servo
amplifier) (About 200s/200%)
The power supplied to the servo amplifier falls below the minimum
specification voltage limit.
