Page: 635 / 1218

Parameters (T) Multi-Function Input Terminal Parameters
FR-A800 5 - 433
Adjust torque only without adjustment of gain voltage (current).
(When changing the gain torque from 150% to 130%.)
Operation
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. (150.00%)
Torque setting change
Turn to change the set value to " ". (130.00%)
Press to enter the setting. " " and " ( )" flicker alternately.
Checking the mode/monitor
Press three times to change to the monitor / frequency monitor.
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.
Tab. 5-169: Adjusting only the torque without adjustment of a voltage (current)
NOTES 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 calibration parameter C16 (Pr. 919) or C38 (Pr. 932). (Refer to
page 5-429.)
E
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.
