Terminal Description about functions and purposes When not in use
ST Start/stop switching signal input
• Short-circuited: Starts operation. The output is gradually
increased during the soft-start time.
• Open: Stops operation. In the phase control, the output is
gradually decreased during the time specified with the soft-start
time.
In the cycle control, the output is stopped regardless of the soft-
start time.
Start/stop can also be switched using the panel or via
communication, instead of using the ST terminal.
The ST terminal is prioritized over the panel and communication.
The concrete behavior is as follows:
• When the start/stop status is switched via the panel or
communication, ST needs to be opened.
• When ST is short-circuited, the output cannot be stopped via
the panel or communication.
• The output started via the panel or communication stops
when ST is opened, short-circuited, and then opened again.
Open
GT Emergency stop signal. This terminal is used to stop the output
in emergencies.
• Short-circuited: Permits the output. If the output has been
switched to the start status via the ST terminal, communication,
or the panel, the output resumes with a soft start when this
terminal is short-circuited.
• Open: Emergency stop. The output is unconditionally,
immediately, and forcibly stopped.
