F-13 Percent Selected Speed Reference Display Enable
This parameter
enables or disables
the fourth monitor
mode display.
Parameter Range: ON = Fourth monitor mode display is enabled.
OFF = Fourth monitor mode display is disabled.
Default Setting: OFF
Step Size: N/A
If F-13 = ON, the current value of the active speed reference can be displayed by
pressing the MODE/ENTER key (while the drive is running) until all three monitor
mode LEDs are on. The active speed reference is displayed as 1 to 100% of maximum
speed (F-04).
If F-13 = OFF, the active speed reference will not be displayed.
Refer to chapter 3 for more information on the monitor mode displays.
F-14 Electronic
This parameter sets
the trip level for the
electronic thermal
overload fault (OL)
when F-15 = ON.
Thermal Overload
Parameter Range: 20% to 100% rated current
Default Setting: 100%
Step Size: 1%
This parameter should be adjusted if the motor current rating is less than the drive
current rating.
Use the formula below to calculate the setting level as a percentage of maximum
continuous current:
e-44 — _Motor FullLoad Current. 100
Drive Output Rated Current
The motor full load current value can be found on the motor nameplate. See table 2.2
or the drive nameplate for the drive rated output value.
F-15 Electronic Thermal Overload Enable
This parameter
enables or disables
the electronic motor
thermal overload
function. This function
operates like a motor
thermal switch to
protect the motor from
overheating.
Parameter Range: OFF = No electronic thermal overload protection.
ON = Electronic thermal overload protection is active.
Default Setting: ON
Step Size: N/A
ATTENTION: Parameter F-15 should be set to ON to prevent damage
to the motor and the drive.
