Relay Usage Count Display Function - Mitsubishi Electric MELSERVO-J5 Series User Manual

Relay usage count display function

Displays the number of times the inrush relay has been turned on/off from the time of shipment and the usage count of the
dynamic brake.
• MR Configurator2 or a controller is required to acquire the number of times the inrush relay has been turned
on/off and the usage count of the dynamic brake.
Precautions
• The interval for recording the number of on/off times of the inrush relay and the usage count of the dynamic brake is 10
minutes. When turning the servo amplifier off/on frequently within this time, there is a possibility that the number of on/off
times of the inrush relay and the usage count of the dynamic brake may deviate from the actual value.
• This function displays the approximate service life. Since the service life varies by the method of use and environmental
conditions, replace the servo amplifier after discovering an error.
Setting method
No setting is required to display the number of times the inrush relay has been turned on/off and the usage count of the
dynamic brake. The servo amplifier always measures the number of times the inrush relay has been turned on/off and the
number of times the dynamic brake has been used.
Service life check method
■How to check with MR Configurator2
