Types of current range
FLC Full load current of the drive (maximum continuous output
current up to 40
o
C ambient temperature). Displayed in Pr 11.32
{0.33}.
I
MAX
A Maximum overload output current of the drive up to 40
o

ambient temperature, derived as follows:
Size 1 to 4: OL> 150% x FLC
CL> 175% x FLC
Size 5: 150% x FLC

Where a parameter is represented by a text value, the value in brackets
in the range column is the setting used for serial communications.
