GROUP
T
(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 (Er3) 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
Pr.919
or
Pr.932
. (Refer to

Operation
1.
Parameter selection
Read
Pr.920
for terminal 1.
Read
Pr.933
for terminal 4.
The present set value is displayed. (150.0%)
2.
Torque setting change
Turn
to change the set value to "130.0%".
Press [SET] to enter the setting. "130%" is set in
Pr.920 (Pr.933)
.
3.
Checking the mode/monitor
Change the status to the monitor mode.
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.

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
777
T053
4 mA input fault operation
frequency
9999
0 to 590 Hz
Set the frequency to continue operation when
the current input is lost.
(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.
