(T) Multi-Function Input Terminal Parameters
426
PARAMETERS
(c) Adjust only torque without adjustment of gain voltage (current).
(When changing the gain torque from 150% to 130%.)
NOTE
• If the gain and bias of torque setting are too close, an error ( ) may displayed at setting.
• For operation outline of the parameter unit (FR-PU07), refer to the Instruction Manual of the FR-PU07.
• Set the bias torque setting using the calibration parameter C16 (Pr.919) or C38 (Pr.932). (Refer to page 423.)

Operation
1.
Parameter selection
Turn to choose (Pr.920) for the terminal 1, and (Pr.933) for the terminal 4.
Press to show the present set value. (150.0%)
2.
Torque setting change
Turn to change the set value to " ". (130.0%)
Press to enter the setting. " " and " ( )" flicker alternately.
3.
Checking the mode/monitor
Press three times to change to the monitor / frequency monitor.
4.
Start
Turn ON the start switch (STF or STR) to apply a voltage across terminals 1 and 5 (4 and 5),
Operation is performed with 130% torque.
Caution
Be cautious when setting any value other than "0" as the bias torque at 0 V (0 mA). Even if a torque
command is not given, simply turning ON the start signal will start the motor at the preset frequency.
When current is input to the analog input terminal 2 and terminal 4, operation when the current input has gone below
the specified level (loss of analog current input) can be selected. It is possible to continue the operation even when the
analog current input is lost.
Pr. Name Initial value Setting range Description
573
T052
4 mA input check selection
9999
1
Continues the operation with output frequency
before the current input loss.
2
4 mA input fault is activated when the current
input loss is detected.
3
Decelerates to stop when the current input loss
is detected. After it is stopped, 4 mA input fault
(E.LCI) is activated.
4 Continues operation with the Pr.777 setting.
9999 No current input check

T053
4 mA input fault operation
frequency
9999
0 to 590 Hz
Set the running frequency for current input loss.
(Valid when Pr.573 = "4")
9999 No current input check when Pr.573 = "4"
778
T054
4 mA input check filter
0 s 0 to 10 s Set the current input loss detection time.
