ECO REFERENCE MANUAL
Description / Notes
Parameters P081 to P085
- These parameters must be set for the
particular motor being controlled by the
inverter. You must use the data provided on
the motor's rating plate.
- Perform an automatic calibration
(P088 = 1) if any of the parameters P081 to
P085 are changed from their factory default
settings.
- When the inverter is set-up for North
America operation (P101 = 1), P081 will
default to 60 Hz and P085 will indicate in hp
(range = 016 to 530).
Defines the motor overload current as a %
of the Nominal motor current (P083) allowed
for up to one minute.
With this parameter and P186, the motor
current can be limited and overheating of
the motor prevented. If this set value is
exceeded for one minute, the output
frequency is reduced until the current falls to
that set in P083.The inverter can be made to
trip by using the relay in conjunction with
P074.
The maximum value that P086 can be set to
is automatically limited by the rating of the
inverter.
0 = disabled
1 = enabled (inverter will trip F004 if
external PTC input goes high
impedance)
