c) Method to adjust torque only without adjustment of gain voltage (current)

(when changing gain torque from 150% to 130%) 

· For operation from the parameter unit (FR-PU04/FR-PU07), refer to the instruction manual of the FR-PU04/FR-PU07.
· Set bias torque setting using calibration parameter C16 (Pr. 919) or C38 (Pr. 932).  (Refer to page 301)

Be cautious when setting any value other than "0" as the bias torque at 0V (0mA). Torque is applied to the motor 
by merely tuning ON the start signal without torque command.
