• Press after step 6 to check the present bias/gain torque setting. The setting cannot be checked after step 7.
 Adjustment by changing the torque without adjusting the voltage (current) (Example of
changing the gain torque from 150% to 130%)
Operating procedure
1.
Selecting the parameter
Turn until "
Press to read the present set value. (150.0%)
2.
Torque setting change
Turn to change the set value to "
Press to confirm the selection. "
3.
Selecting the mode and the monitor item
Press three times to select the monitor mode, and change the monitor item to the frequency.
4.
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.
