CAUTION
• The internal resolution of the torque command is 0.024% (100/2
• The range of torque setting is from -327.68% to 327.67%. (-400% to 400% when shipped from the factory)
• A negative value can not be input from the control panel DU04-01 and parameter unit PU04V, a value can not be set in 0.01%
increments. The setting range is from 600 to 1400% and setting increments is 1% increments. When the value set from the
CC-Link is read from the PU04V or DU04-01, the value is also converted to 600 to 1400 for display.

(1) Calibration of torque command terminal 3
Refer to the chart on the right for the relationship
between torque setting input voltage and output
voltage. The torque setting input signal is in
proportion to the output torque. Note that the
motor-developed torque varies with the motor
temperature.
Use Pr. 904 and Pr. 905 to adjust bias/gain of
the terminal 3. (Refer to page 51.)
