6.3.11 Energy Counter
6.3.12 Resettable Energy Counter
Energy counter as kWh
Resettable energy counter as kWh
Energy counter
This counter holds the value of total amount of energy taken from a supply network. This counter cannot be reset. The
values are read only.
This counter holds the value of total amount of energy taken from a supply network since the counter was last reset. For
resetting this counter see Chapter 6.3.2”. The values are read only.
This counter is in registers 40211d to 40212d and is a 32-bit floating point (IEEE 754) value containing the number of
kilowatt-hours (kWh) that is in the drive’s energy counter. This value is read-only.
This counter is in registers 40311d to 40312d and is a 32-bit floating point (IEEE 754) value containing the number of
kilowatt-hours (kWh) that is in the drive’s 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.
Example: If energy = 1200, format = 52, unit = 1, then actual energy is 12.00 kWh.

Purpose Description
40201 201 Energy Amount of energy taken from a supply network.
40202 202 Format
The last number of the Format field indicates
the decimal 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
