Step 6 Performing the tension controlled operation
1.
Set the tension command value.
Analog setting: Set a desired value using the internal/external potentiometer or external DC voltage.
Digital setting: Set a desired operation data number based on a combination of ON/OFF statuses of M0
to M2 inputs.
2.
Set the direction in which tension generates in the system parameter for motor rotation
direction [SyS-1-06].
3.
Turn the CW input ON.
Tension controlled operation starts at the tension command value set in step 1.
Note
• The CCW input is not accepted in high function mode I or high function mode II.
• Operation data numbers cannot be changed when the CW input is ON.
4.
Turn the CW input OFF.
Motor excitation turns off and the motor performs the free-run stop.
Refer to p.116 for details on the timing chart.
Step 7 Setting the parameters
Set the following parameters as necessary.

Friction torque correction
Correct the torque load based on the friction of mechanical parts. Set the output torque during idle operation
of the equipment in the application parameter for friction torque correction [APP-4-04]. The value based on
the output torque during idle operation can be monitored by the OPX-2A or MEXE02.
Setting range: 0 to 50%
Initial value: 0%

Tension control gear ratio
When a deceleration mechanism is used between the motor output shaft and winding (or unwinding) shaft, set
a gear ratio in the system parameter for tension control gear ratio [SyS-1-04]. When using the geared motor,
include the gear ratio of such geared-motor as well.
Setting range: 1.0 to 1,000.0
Initial value: 1.0
Note
When a system parameter has been changed, the new parameter will become effective
after the power is cycled. If a 24 VDC power supply is used, also cycle the 24 VDC power
supply.

Acceleration/deceleration correction filter (high function mode II
only)
Set the correction filter time constant for acceleration/deceleration in the application parameter for
acceleration/deceleration correction filter [APP-4-03]. Increase the value if vibration occurs when the motor
is operating.
Setting range: 10 to 500 ms
Initial value: 100 ms
