Utilization of output holding function

WARNING
Before setting the output holding function, be sure to fully understand the details of this function.
If the output holding function is not activated, a serious problem may occur.
Select the output unit operation for the output holding function. If a transmission error occurs, the output unit will
operate in accordance with the selected operation. However, if the power is not supplied to the output unit, the
output holding function will not be activated. If the normal transmission is restarted, normal operation will be per-
formed.
● Output holding function: ON
• If a transmission error is detected, the output conditions detected just before occurrence of the error will be
held.
● Output holding function: OFF
• If a transmission error is detected, all the outputs will be turned off.
Examples of use:
<Output holding function: ON>
• Use this function if the transfer unit uses the vacuum pick-up function.
• Use this function if a manifold is used for operation of the pressure unit.
• Use this function if non-holding of the current conditions may damage the machine (workpieces).
<Output holding function: OFF>
• Use this function if a transfer unit is adopted to perform line transfer operation.
• Use this function if a motor is adopted as the drive unit.
• Use this function if the items being transferred will be obstacles at resetting operation.
We have predicted the cases that need this function, and listed above as examples.
NOTE
However, to actually set the output holding function for your system, consider the environ-
mental conditions of your system.
