Basic Knowledge For Operation; Entering Run/Stop Signals (Use Of Mc1) --12 - Mitsubishi LE-40MTB-E Instruction Manual

5. Basic knowledge for operation

5.1 Entering Run / stop signals (use of MC1)
The minimum necessary preparation for tension control is described in "Adjustment flow for trial operation"
on page 10.
This section explains the use of start/stop (MC1) contacts essential to the step (4) operational check in au-
tomatic mode.
1. Run / stop (MC1 input)
• The contacts interlocked with the Run/
stop operation of the machine (such as
the feed motor Run/stop) are connected.
Press the automatic mode switch to en-
ter automatic mode. With the MC1 input
made and after a lapse of time set in the
start timer, the automatic control will
start. See the figure on the right.
• When this input is turned off, the stop
gain and the stop bias become valid until
the stop timer times up. After that, the
stall values become valid.
(The start timer and stop timer will be
discussed later. See the next page for
more about the stall.)
2. Automatic mode indicator lamp
• The lighting conditions of the auto-
matic mode switch, start/stop in-
put (MC1) and the state of the
automatic mode indicator are as
the figure on the right.
3. Connection
• Use a micro signal switch commensurate with DC8V
4mA as the input contacts. Connect the contacts
across MC1 and MCC.
