Tension sensorless torque control details
Tension command through the CC-Link / CC-Link IE Field Network /
PROFIBUS-DP (Pr.804 = "1, 3, 5, 6")
• Set the tension command via the CC-Link communication (FR-A8NC), CC-Link IE Field Network communication (FR-
A8NCE), or PROFIBUS-DP communication (FR-A8NP).
• Set the tension command the same way as the torque command. (Refer to the Instruction Manual of each option for
details.)

Can also be set from operation panel or parameter unit.
∗2
The tension command can also be performed by setting a value in Pr.365 or Pr.366.
∗3
The setting varies with the Pr.1401 setting.
∗4
When Pr.1401 = "0", enter the setting value multiplied by 100. When Pr.1401 = "1", enter the setting value multiplied by 10. For example, enter
10000 to set 100.00N when "0" is set in Pr.1401.
NOTE
• For the details of FR-A8NC, FR-A8NCE, FR-A8NP setting, refer to the Instruction Manual for the respective communication
options.
• For the details of the setting using the PLC function, refer to the PLC Function Programming Manual.
Tension command by 16-bit digital input (Pr.804 = "4")
• Execute tension command by 12-bit or 16-bit digital input using FR-A8AX (plug-in option).
• When a value other than "0" is set in Pr.1403 or Pr.1405, use Pr.1403 or Pr.1405 to calibrate the tension command value
input to the FR-A8AX.
• When "0" is set in both Pr.1403 and Pr.1405, the digital value input to the FR-A8AX is used as it is as the tension command
value.
• Use Pr.1401 to set the maximum tension command value.
NOTE
• For the details of the FR-A8AX setting, refer to the Instruction Manual of the FR-A8AX.
