(2) Regenerative load factor monitor output
The regenerative load factor monitor output is convenient for checking the effective power of the
regenerative resistor.
Regenerative load factor monitor signals are output as follows:
Effective power of regenerative resistor/Monitor reference power (W) = 0.3 V
(The monitor reference power is set at the value listed in Table 9-5.)
The output voltage is updated every second.
The effective power of the regenerative resistor is typically calculated as follows:
When the power is measured as in the figure above, the following calculation is possible:
Effective power of regenerative resistor (W) =
The result is acceptable if it is within the allowable effective power of the regenerative resistor.
1 When T (1 cycle) is 1 second or shorter, measure the effective power by repeating
cycles for more than 1 second.
The regenerative resistor load factor monitor assumes that the regenerative resistor values are as in
the table below.

Resistance value (Ω)
Monitor reference power
* For the allowable effective power of an external regenerative resistor,
refer to "Table 9-21 External Regenerative Resistor Combination Table".
* After switching, Func2 bit 4 is enabled by turning on the control power supply again.
2 Since the maximum output voltage of the analog monitor is 3 V, if the power consumption
with a regenerative resistor in a second exceeds 10 times of the reference power, it will
continue for the next 1 second.
3 The regenerative load factor monitor may cause errors of ±30%.
4 The monitor reference power changes depending on the regenerative resistor OL time
select in Func2 bit 4.
5 When the built-in regenerative resistor is used, use the built-in regenerative resistor
absorbing power monitor RegP (Mode5 Page17) of the remote operator.
