11.3.9 Confirmation method of regeneration power PM in actual
operation
Regeneration power PM can be easily confirmed in the digital operator or by R ADVANCED
MODEL setup software.
■
Digital operator: Monitor mode ID40 "Regenerative Resistor Operation Percentage monitor"
■
Setup software: Monitor display ID40 "Regenerative Resistor Operation Percentage monitor"
* The monitor value of the regenerative resistor operation percentage shows the operating rate of
regeneration circuit.
* The display range is 0.00% - 99.9%.
■
The actual regeneration effective power PM can be calculated from this monitor value by
following equation.
 Input Supply Voltage: In case of 200 VAC specification
 Input Supply Voltage: In case of 100 VAC specification
 Input Supply Voltage: In case of 400 VAC specification
■
Calculation Example
Input Supply Voltage: [200 VAC Specification]
Regeneration resistance value: 50
Ω
[Built-in Regenerative Resistor]
Monitor Value (RegP): 0.12%
* The regeneration power calculated from this monitor value continues to be the target until the
end of operations. Regeneration power varies with the voltage fluctuation of the input power
supply and changes across the ages of the servo amplifier and the loading device.
* Be sure to opt for selection of regeneration resistance based on the regeneration effective power
"PM" found from calculation of a pattern of operation and regeneration power.
* Install the external regeneration resistor on equipment, and measure the temperature of the
external regeneration resistor by the operating condition that the regeneration effective power
“PM” becomes the maximum. Then do sufficient mounting check of alarm not being generated. In
addition, it takes 1 to 2 hours until the temperature of the external regeneration resistor is
saturated.
