Mitsubishi Electric FR-E800 Instruction Manual page 410

 Adjustment by changing the torque without adjusting the current (voltage) (Example of
changing the gain torque from 150% to 130%)
Operating procedure
1.
Selecting the parameter
Turn the setting dial or press the UP/DOWN key until "C40" (Pr.933) appears.
Press the SET key to show the present set value. (150.0%)
2.
Torque setting change
Turn the setting dial or press the UP/DOWN key to change the value to "130.0". (130.0%)
Press the SET key to confirm the setting. "130.0" blinks.
3.
Selecting the mode and the monitor item
Press the MODE key three times to select the monitor mode and to monitor a frequency.
4.
Start
Turn ON the start switch (STF or STR) to apply a voltage across terminals 4 and 5.
Operation is performed with 130% torque.
NOTE
• If the current (voltage) values at the gain and bias torques are too close to each other, an error ("Er3") may be indicated.
• Use the calibration parameter C38 (Pr.932) to set the bias torque. (Refer to
• For operation outline of the parameter unit (FR-PU07), refer to the FR-PU07 Instruction Manual.
CAUTION
• When setting a value other than "0" as the bias torque, note that simply turning ON the start signal will supply torque to
the motor even if a torque command is not given.
