Relay usage count display function
Displays the number of times the inrush relay has been turned on/off from the time of shipment.
• MR Configurator2 or a controller is required to acquire the number of times the inrush relay has been turned
on/off.
Precautions
• The interval for recording the number of on/off times of the inrush relay 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. The servo amplifier always
measures the number of times the inrush relay has been turned on/off.
Service life check method
