4A0930 and 4A1200: 1 A units.
<2> The values of U1-03, U2-05, and U4-13 are displayed on the digital operator in units of amperes. When those monitors are checked using
MEMOBUS/Modbus communications, the monitor values in MEMOBUS/Modbus communications are displayed as: numeric value / 8192 × drive
rated current (A) from the condition "192 (maximum value) = drive rated current (A)"

Displays the first to the fourth most recent faults.
Fault Message o
Displays the fifth to the tenth most recent faults.
After ten faults, data for the oldest fault is deleted. The most

appearing in U3-02. The data is moved to the next monitor
parameter each time a fault occurs.
Displays the cumulative operation time when the first to the
fourth most recent faults occurred.
Elapsed Time o
Displays the cumulative operation time when the fifth to the
tenth most recent faults occurred.
