8 System Setup
8.21Preventive Maintenance Function
MH900, DX200 Controller
8.21.6 Preventive Maintenance for the Hardware
This function estimates the life span of the controller components by
calculating the consumed amount with considering the usage environment
and the load, and outputs general signals to be the reference for the
replacement time.
The function overview is described below.
8.21.6.1 Target Components for Diagnosis
Regarding the following, calculations of the consumed amount and
outputs of the general signals to be the reference for the replacement time
are performed.
• Cooling fan*
• Capacitor
• Amplifier IGBT
• Contactor
• Motor (numbers of revolution and reverse revolution are displayed)
*Even though a fan is an one of target components, some models do not
have the fan. Refer to the INSTRUCTIONS for the each manipulator to
confirm if it has the fan.
8.21.6.2 Replacement Time Display
Stepwise Display of Replacement Time
For each component, a judgment from A to D is displayed, and it can be
used as the reference for the replacement time.
Signal Output of Replacement Time
If any of the components is judged as D, ON signal is output from the
general output which is set as “Alarm signal” of the file.
However, only one signal for this general signal can be output for one
controller.
Judgment

Status
A New - Used about half of its life span
B Used about half of its life span
C Used about half of its life span - Time to replace (reference)
D Time to replace (reference)
