Setting
143 Overload level ratio OLWL % 50 to 100 100
With the estimated risen temperature to generate overload alarm set as 100%, the 048
overload warning (message level) alarm is output when the motor temperature has exceeded
the ratio set in this parameter. Judgment will not be executed if set to 100. (Refer to 8.2 [62] for
the alarm output.)
[Applied: prevention function]
By setting this parameter, warning output notifies you before the equipment stops by error in
case that the motor temperature rises due to load condition change caused by dry-up of grease
or wear-out of components. Warning output (ALML Signal) can be conducted with PIO
*
or
fieldbus.
* PIO output, parameter No.151 set to 0.

Operation
Range
Time
The current applied to the motor increases because of sliding resistance increase
due to lack of maintenance of guide and ball screw or excess load applied on the motor.
As a result, overload error occurs and the device stops the operation.
The current applied to the motor increases gradually as the sliding resistance gets
higher without supplying grease on guide and ball screw.
Warning will be generated if the current reaches the threshold that you set.
At this time, the device will not stop, but have inspection and maintenance
work held and remove the cause immediately.

As RCP6S and RCM-P6PC are not applicable for this feature, do not attempt to make any change
from the initial setting.
