• When the terminal command LE ("Enable communications link via RS-485") is assigned
to a programmable, digital input terminal, turning LE ON enables the settings of H30.
When LE is OFF, those settings are disabled so that both frequency commands and run
commands specified from the inverter itself take control.
H42 Capacitance of DC Link Bus Capacitor
H42 displays the measured capacitance of the DC link bus capacitor.
H43 Cumulative Run Time of Cooling Fan
H43 displays the cumulative run time of the cooling fan.
H44 Startup Counter of Motor 1
H44 displays the startup times of motor 1.
H45 Mock Alarm H97 (Clear Alarm Data)
H45 causes the inverter to generate a mock alarm in order to check whether external
sequences function correctly at the time of machine setup.
Setting the H45 data to "1" displays mock alarm
err
on the LED monitor. It also issues
alarm output (for any alarm) ALM (if assigned to a digital output terminal by E20 or E27).
(Accessing the H45 data requires simultaneous keying of "
key + key.") After that, the
H45 data automatically reverts to "0," allowing you to reset the alarm.
Just as for data (alarm history and relevant information) of those alarms that could occur in
running the inverter, the inverter saves mock alarm data, enabling you to confirm the mock
alarm status.
To clear the mock alarm data, use H97. (Accessing the H97 data requires simultaneous
keying of "
key + key.") H97 data automatically reverts to "0" after clearing the alarm
data. For details, refer to the description of H97.
H47 Initial Capacitance of DC Link Bus Capacitor
H47 displays the initial value of the capacitance of the DC link bus capacitor.
H48 Cumulative Run Time of Capacitors on Printed Circuit Boards
H48 displays the cumulative run time of the capacitors mounted on the printed circuit boards.
