FR200 Series Vector control inverter
- 113 -
Cold start: Motor protection operation time in response to an overload situation that was suddenly
reached when starting a stationary motor.
Hot start: Motor protection operation time in response to an overload situation that occurred
during sustained operation at rated current.

F11.18
Overload alarm
Range:00
～
11
Default:00
Unit's place: detection option
0: Always detect
Overload alarm works all the time during drive running.
1: Detect at constant speed only
Overload pre-alarm only works during constant-speed running of inverter.
Decade: compared object
0: Rated current of motor
Compared object is the rated current relative to motor, and display " A11" when the alarm is given
under this setting
1: Rated current of drive
Compared object is the rated current of drive, and display " A12" when the alarm is given under
this setting.
F11.19
Overload alarm threshold
Range:20.0
～
200.0%
Default:130.0%
When 0 is set at decade of F11.18, this set value is a percentage compared to rated current of
motor. When 1 is set of that, this set value is a percentage compared to rated current of drive.
F11.20
Overload alarm activated time
that exceeding threshold
Range:0.1
～
60.0s
Default:5.0s
Set the lasting time that overload alarm is activated when output current of drive is bigger than the
threshold set by F11.19.

overheat
Temperature
Default: Model
defined
Sets the threshold of drive t overheat alarm. When the maximum internal temperature of drive is
higher than this value, the drive displays thermal alarm code “A14", but won’t influence the running.
F11.22
Detection level of power loss
Range:5.0
～
100.0%
Default:20.0%
F11.23
Detection time of power loss
Range:0.1
～
60.0s
Default:5.0s
When the output current of the AC drive is lower than the detection level (F11.22) and the lasting
time exceeds the detection time (F11.23), fault reported
