TENSION SENSORLESS TORQUE CONTROL
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.)
∗1
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.
