c) Method to adjust torque only without adjustment of gain voltage (current)
(when changing gain torque from 150% to 130%)

monitor/frequency monitor.
6.
Apply a voltage across the inverter
terminals 1 and 5 (across 4 and 5) and
turn on the start command (STF, STR).
Operation starts with 130% torque.
REMARKS
· 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 306 )
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.
