E33
OL function signal (Mode select)
The OL function signal includes two variations:
"overload forecast by means of the function of
the electronic thermal overload relay" and
"overload forecast by means of output current".
Setting: 0 Electronic thermal overload relay
1 Output current

Function
Outline
0
Electronic thermal overload relay
Overload forecast using the
characteristics of the electronic
thermal overload relay which
show inverse time limit
characteristics against the
output current.
The operation selection of the
inverse time limit
characteristics and the thermal
time constant are the same
characteristics as those of the
electronic thermal overload
relay (F10, F12) for motor
protection. To use for the
forecast, set an earlier output
than the electronic thermal
overload relay for motor
protection.
1
Output
current
When the output current
exceeds the set current for a
period longer than the set time,
an overload forecast is issued.
E34 OL function signal (Level)
Determine the level of the electronic thermal
overload relay or output current.
Setting range:
Rated inverter output current x (20 to 200%)
The operation cancellation level is 90% of the set
value.
E35 OL function signal (Timer)
When E33 "OL function signal (Mode select)" is
set at "1" (output current), set the time taken until
the forecast is issued.
Setting range: 0.1 to 60.0 s
E40 Display coefficient A
E41 Display coefficient B
Use these functions as conversion coefficients
for determining the display value (process
amount) of the load speed, line speed and
target value and feedback amount of the PID
adjuster.
Setting range
Display coefficient A: 0.00 to 200.0
Display coefficient B: 0.00 to 200.0
Load speed and line speed
Use E40 "Display coefficient A".
(Displayed value) = (Output frequency) x (0.01
to 200.0)
The effective value of the display data is 0.01 to
200.0. Therefore the display is limited by the
minimum value of 0.01 and the maximum value
of 200.0 even if the value exceeds the range.
Target value and feedback amount of PID
adjuster
Set the maximum value of the display data at
E40 "Display coefficient A" and set the
minimum value at E41 "Display coefficient B".
Display value = (Target value or feedback
amount) x (Display coefficient A - B) + B
E42 LED display filter
The data of "LED monitor" includes data for which
display of the changing moment is not necessary.
This type of data can be provided with a filter for
flicker prevention.
Setting range: 0.0 to 5.0 s
The target display items are the output current
and output voltage.
