 Adjustment by changing the torque without adjusting the voltage (current) (Example of
changing the gain torque from 150% to 130%)

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.
NOTE
• If the voltage (current) values at the gain and bias torques are too close to each other, an error ("
indicated.
• For operation outline of the parameter unit (FR-PU07), refer to the Instruction Manual of the FR-PU07.
• Use the calibration parameter C16 (Pr.919) or C38 (Pr.932) to set the bias torque. (Refer to
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 supply torque to the motor.
