Hardware logic control stop signal at disconnection (Y6)
This signal is enabled when "Valid" is set for "Hardware logic control valid/invalid during disconnecting" in "Switch Setting".
Do not set "Valid" for "Hardware logic control valid/invalid during disconnecting" in "Switch Setting" when a head module is not
connected. If "Valid" is set, this signal needs to be on at a hardware logic control start.
■

When "Hardware logic control stop enable/disable setting during disconnecting" is set to "Valid" and both of the following
conditions are satisfied, the hardware logic control is started.
• When this signal is on
• When Hardware logic control start request (Y4) is turned on
■
Stopping the hardware logic control
When any of the following conditions is satisfied, the hardware logic control is stopped.
• When this signal is turned off
• When Hardware logic control stop request (Y5) is turned off while this signal is on
Hardware logic control stop flag clear request at disconnection (Y7)
This signal is enabled when "Valid" is set for "Hardware logic control valid/invalid during disconnecting" in "Switch Setting".
Turn on and off this signal to turn off Hardware logic control stop flag at disconnection (X7).
For the timing of turning on and off this signal, refer to the following.
