U: Monitor Constants
The following settings are made with the monitor constants (U constants): Setting constants for monitoring in
drive mode.
Status Monitor Constants: U1
The constants used for monitoring status are listed in the following table.
* 1. The unit is set in o1-03 (frequency units of reference setting and monitor).
* 2. The unit differs according to the Inverter capacity. (The unit is 0.01 A for an Inverter capacity of 0.4 to 7.5 kW, and 0.1 A for an Inverter capacity of
11 kW and larger.)
