6. Functions of Input/Output Signals
6.3

Output signals

6.3.1

Powder clutch/brake control output

• Control output for powder clutch/brake of 24 VDC and 3 A or less.
6.3.2

Control the output for the power amplifier and AC servo amplifier

1) To use the powder clutch/brake having a rated current of 3 A or more, input this signal to the power
amplifier compatible with the rated current of the powder clutch/brake, and connect the powder clutch/
brake to the output terminal of the power amplifier.
2) To control a servomotor in torque control mode, input this signal to the torque setting input terminal of the
servo amplifier.
6.3.3

Tension monitoring output

• The monitoring output signal outputs voltage in proportion to the target tension value for automatic control
or the material tension value detected by the tension detector.
• Set the signal type by DIP switch 4.
• DIP switch 4 = ON - - - - - Tension set (target tension) monitoring output
• DIP switch 4 = OFF - - - - Tension monitoring output
• For the output voltage range 0 to 5 V, the tension range will be 0 to set full-scale tension value.
6.4

Zero tension detection signal

6.4.1

Zero tension detection function

• In case a number other than zero (initial value) has been set for the zero
tension set value, the contact output will be turned ON when the tension
monitor value is smaller than the zero tension set value.
• When the value is set to zero (initial value), the contact output is OFF
normally.
• If tension is restored and increases, the contact output will be turned OFF
when the tension monitor value becomes over the "zero tension set value
+ hysteresis value."
• Hysteresis value - - - - - 1/64 of tension full-scale value. (minimum value : 5N)
6.4.2

Setting the zero tension detection value

• In the adjustment mode (power ON with DIP.SW8 OFF), select item number 26, and then set the value.
