6 - Parameter Descriptions
F40: Energy Save Level
Range:
0-30% (Default: 0%)
Description:
This function is used to reduce the output voltage in applications that do not
require high torque and current at its steady speed. If the energy save level is set
at 20%, drive reduces its output voltage after accelerating to the reference
frequency (steady speed). This function may cause over-current trip due to the
lack of output torque in a fluctuated load. This function does not work with 0%
set value.
z
Note: This function is not recommended for a large load or for an application
that need frequent acceleration and deceleration.
z
Note: This function does not work when ‘Sensorless’ is selected in H40
[Control Mode, page 95].
F50: Electronic Thermal Selection [ETH]
Range:
0 (No), 1 (Yes), (Default: 0)
Description:
This function provides motor overload protection. The drive calculates the
temperature of the motor using several parameters. The drive faults and displays a
trip message when the electronic thermal function is activated.
Parameters F51-53 must be set for proper operation.
