5.3 Description of Function Codes 5.3.5 H codes (High performance functions)
Cumulative run time of capacitors on printed circuit boards (H48)
Cumulative run time of
capacitors on printed circuit
boards
Displays the cumulative run time for the capacitor on the
PCB .
• Data setting range: 0 to 99990 hours (10 hour
increments)
When replacing capacitors on printed circuit boards, clearing or modifying H48 data is required. For details, refer to
the maintenance related documents.
Cumulative run time of cooling fan (H43)
Cumulative run time of
cooling fan
Displays the cumulative run time for the cooling fan.
• Data setting range: 0 to 99990 hours (10 hour
increments)
When replacing the cooling fan, clearing or modifying H43 data is required. For details, refer to the maintenance
related documents.
Startup count 1 Reference function code: H81 Warning selection 1
Counts the number of inverter starts and displays it up to 65535 times. Check the displayed number on the
maintenance screen of the keypad, and use it as a guide for maintenance timing for parts such as belts. To start
the counting over again, e.g. after a belt replacement, set the H44 data to “0”. By assigning warnings with H81, and
the count becomes zero, CnT appears on the keypad, and warning “L-ALM” is output to notify the user.
Simulation failure
Related function codes: 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 any of E20 to E24, and E27).
Accessing the H45 data requires simultaneous keying of the key + key. After that, the H45 data
automatically reverts to “0,” allowing you to reset the alarm.
Same as other alarms that could occur when 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 the key +
key.) H97 data automatically returns to “0” after clearing the alarm data.
A mock alarm can be issued also by simultaneous keying of the key + key on the keypad for 5
seconds or more.
Starting mode (Auto search delay time 2) (Refer to H09)
Refer to the function code H09 section for details on the starting characteristics (auto search wait time 2).
Initial capacitance of DC link bus capacitor, Cumulative run time of capacitors on
printed circuit boards (Refer to H42)
For details, refer to the description of H42.
