Motor Data
046 [Mtr NP Pwr Units]
Selects the motor power units to be used.
“Convert HP” = converts all power units to
Horsepower.
“Convert kW” = converts all power units to
kilowatts.
Note: This parameter does not get changed with a
“Reset to Defaults”.

047 [Motor OL Hertz]
Selects the output frequency below which the
motor operating current is derated. The motor
thermal overload will generate a fault at lower
levels of current below this output frequency.
Default:

049 [Motor Poles]
Defines the number of poles in the motor.
Note: Maximum value changed from 12 to 18 for
firmware revision 4.001.

050 [Motor OL Mode]
“Pwr Cyc Ret” - If “0”, the value of parameter 220 [Motor OL Count] is reset to zero by a drive reset
or power cycle. If “1”, the value of parameter 220 [Motor OL Count] is maintained. A “1” to “0”
transition resets parameter 220 [Motor OL Count] to zero.
Note: Added for firmware revision 3.001.
