Operation selection functions 4 (Pr. 800 to Pr. 809)
(3) Setting from the CC-Link (16bit two’s complement)
(1) Terminal 3 calibration (Pr. 804 = 0)
The torque command value for the analog input of
the terminal 3 varies with Pr. 904 and Pr. 905 as
shown on the right.
(2) Digital input from parameter (Pr. 804 = 1)
Digital setting of the torque command can be made
by writing the torque command value to Pr. 805 or
Pr. 806 by communication. The torque command
can also be specified by parameter direct setting.
In this case, set the speed limit value to an
appropriate value to prevent overspeed.
The relationship between the Pr. 805 or Pr. 806
setting and actual torque command value at this
time is shown on the right. On the assumption that
1000% is 0%, the torque command is indicated by
an offset from 1000%.
CAUTION
When writing the torque command value by communication (Pr. 804 = 1, Pr. 804 = 3), there is a limit on
the number of write times to E
2
PROM. When the value is changed often, write it to RAM. (When Pr. 804 =
1, set "1" in Pr. 342 "E
2
PROM write selection" to select write to RAM.)

CAUTION
• The internal resolution of the torque command is 0.024% (100/2
12
) and the fraction less than the
resolution is rounded off.
• 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 DU04-1 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 DU04-1, the value is also
converted to 600 to 1400 for display.
