5. Automatic Operation and Functions

5. Automatic Operation and Functions
• Basic setting for automatic operation is completed when adjustment and initial setting described in Sec. 4 are
completed.
• This section describes automatic operation and functions necessary for starting or stopping the machine.
• Set or use each function whenever necessary.
5.1

Operation at starting or stopping machine

5.1.1

Operation at starting machine

• Turn ON or OFF the [RUN] input signal depending on the
operation status of the machine (started or stopped).
• When the [RUN] input signal is OFF, the set manual value
will be output or the value stored in the memory will be
output. - - - - - - - - - - - - - - - - - - - - Refer to Sec. 5.2.
• In the automatic control mode, turning on the [RUN] input
signal will start automatic operation from the output value
set for the previous operation. The automatic operation
will be continually perform while the [RUN] input signal is
left at the ON status.
• At the start of the machine, turn ON the [RUN] input signal
after the completion of acceleration to fix the output during
acceleration and to minimize the change in the tension.

• The same operation can be perform by using the function of manual output 1. - - - - Refer to Sec. 6.1.2.(4).
5.1.2

Operation at stopping machine

When the machine is stopped, the tension may be changed by the inertia of the reel. To prevent such change
in the tension, set the stop timer and the stop gain.
• When the [RUN] input signal is turned OFF during the automatic operation, the stop timer will be activated.
• When the stop timer is activated, the output value will be sent out depending on the stop gain set value and
by multiplying the output just before [RUN] input signal was turned OFF by the stop-gain set value. From
this output value, automatic control will continue after the activation of the stop timer.
• After the end of the stop timer, the output value stored in the memory (output just before turning off the
[RUN] input signal) or the output value set by manually setting 1 or 2 functions will be output depending on
the ON/OFF status of the output memory signal (assigned to the MI1, MI2, or MI3).
• When the stop timer is activated, the AUTO indicator LED(11) and the MANUAL indicator LED(10) will
extinguish.
• When manual operation (the manual control mode selector key(13) is on), the stop timer will not function.
