Table 42. Resettable energy counter as kWh
Resettable energy counter
These registers hold three values for the energy counter, amount of energy used, format of the
energy value and unit of the energy value.
For compatibility with VACON
®
100 family internal Modbus TCP/UDP and the OPT-CI option board,
this counter is found from two different register areas: 40301
d to 40303d and 301d to 303d.
Example: If energy = 1200, format = 52, unit = 1, then actual energy is 12.00 kWh.
Table 43. Resettable energy counter
7.3.2.5.9. FAULT HISTORY
The fault history can be viewed by reading from address 40401 onward. The faults are listed in
chronological order so that the latest fault is mentioned first and the oldest last. The fault history
can contain 29 faults at the same time. (In VACON
®
20, VACON
®
20 X and VACON
®
20 CP it is
possible to read nine faults). For compatibility with VACON
®
100 family internal Modbus TCP/UDP
and the OPT-CI option board, this counter is also found from input register area: 401
d to 403d.
NOTE! Reading the fault history items is slow. Reading all 30 items at once might take up to three
seconds depending on drive type and firmware versions.
The fault history contents are represented as follows:
Address Description
40311 High data
40312 Low data

Purpose Description
40301 301 Energy Amount of energy taken from a supply network.
40302 302 Format
The last number of the Format field indicates the deci-
mal point place in the Energy field.
Example:
40 = 4 number of digits, 0 fractional digits
41 = 4 number of digits, 1 fractional digit
42 = 4 number of digits, 2 fractional digits
