Parameter Descriptions 7-35
F51 Electronic thermal level for 1 minute
Range: 50-200 [%]
Default: 150
Access Tunable
See Also: F50, F52-F53
This parameter sets the maximum current capable of flowing to the motor
continuously for 1 minute. The set value is a percentage of P32 – Motor
Rated Current. It can not be set lower than F52 – Electronic thermal level
for continuous.
F52 Electronic thermal level for continuous
Range: 50-15 [%]
Default: 10
Access Tunable
See Also: F50, F51, F53
This parameter sets the amount of current to keep the motor running
continuously. It cannot be set higher than F51 – Electronic thermal level for
1 minute.
F53
Motor cooling method
Range: 0 = Standard Motor
1 = Variable Speed Motor
Default: 00
Access Tunable
For a Standard Motor, cooling effects decrease when a motor is run at low
speed. A Variable Speed motor is a special motor that uses a separately
powered cooling fan to maximize cooling effect even at low speed.
