[For driver unit]
The driver overload warning (message level error) should be detected when the ratio of the load
assuming the presumed motor raised temperature that could generate the driver overload error
as 100 % (hereinafter described as overload level) has exceeded the value set in the parameter.
By setting a parameter separately, the driver overload warning can be output to a port.
The indication of the ratio above and the output port should be done in the parameters below.
(1) Driver Unit Parameter No. 143 “Overload Warning Loading Level Ratio”
The ratio should be set to detect Error No. 22C “Motor Drive Control Error” assuming the
overload level (driver overload error loading level) to detect Error No. 61A “Overload Error”
(cold start level error) as 100 (%).
The setting range should be “50 to 100 (%)” and if 100 (%) or a number out of the range is
set, the driver overload warning and the driver overload warning output should get invalid.

(2) Axis Parameter No. “Driver Overload Warning Output Number”
A port number to conduct the driver overload warning output (break contact) should be set. If
an output port number other than 0 is set in this parameter, the driver overload warning output
activates. When 0 or a number out of the range is set, the driver overload warning output
should get invalid.

[In case of EC connection unit (ELECYLINDER)]
● For ELECYLINDER, it is not in the parameters, but in the maintenance information screen in
the teaching tool to set the ratio. When each setting values are exceeded, there should be
“Maintenance Warning 3” generated and the status LED on ELECYLINDER should flash in
green and red in turns to notify.
● When the motor temperature rise value falls below the ratio set as “overload warning level”,
“Maintenance warning 3” will be automatically cleared.
● When “Maintenance warning 3” is output, investigate the cause of the increase in load.
Maintenance such as greasing or reviewing the operating conditions is recommended.
● Setting it to “100 %” will disable this function.
All of maintenance warning LEDs from 1 to 3 on
ELECYLINDER flash in green and red in turns.
