FUNCTION CODES
Chap 5
■ Cumulative run time of capacitors on printed circuit boards (H48)
Function code Name Data
H48 Cumulative run time of
capacitors on printed circuit
boards
Displays the cumulative run time of capacitor on the
printed circuit board in units of ten hours.
• Data setting range: 0 to 9999 (0 to 99990 hours)
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)
Function code Name Data
H43 Cumulative run time of
cooling fan
Displays the cumulative run time of cooling fan in units of
ten hours.
• Data setting range: 0 to 9999 (0 to 99990 hours)
When replacing the cooling fan, clearing or modifying H43 data is required. For details, refer to the maintenance
related documents.
H44
Startup count for motor 1
H44 counts the number of inverter startups and displays it in hexadecimal format. 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 “0000.”
H45
Mock alarm
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, E21 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
eypad for 5
seconds or more.
Starting mode (Auto search delay time 2) (refer to H09)
For details, refer to the description of H09.
H47, H48
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.
