D Inverter Overheat Warning (Set Value = 21)
If this signal is input, "OH3" will be displayed by the Inverter.
This signal can be used to detect the overheating of the Braking Resistor Unit, Control Unit, and motor.
D Analog Frequency Sample and Hold (Set Value = 22)
If this signal is ON for 0.1 s or more, the Inverter will sample and hold the analog frequency reference
being used.
The Inverter will continue to keep the frequency on hold.
The Inverter will save the frequency on hold as frequency reference 1 value of n025 so that the value will
not be lost after the Inverter is turned OFF if n044 is set to 1.
