Emergency stop function (disabled by the factory setting
)
•
The emergency stop function shuts off the inverter output in response to a command from a
hardware circuit via an intelligent input terminal without the operation by internal CPU software.
When using this function, refer to the user
′
s guide for HF-430NEO.
•
This function uses STO function of HF-430NEO , but functional safety certification become invalid.
(SIL3, Cat.4)
●
Risk of injury and electric shock!
•
This function does not shut off the power supply for main circuit and peripheral circuit.
While power is supplied to the inverter, do not touch any terminals of the inverter or any
power cables.
•
When the emergency stop function is enabled, input terminal DFL is used exclusively for this
function.
•
Configure the input terminal [DFL] function (CA-03) to “no: 000 (Not use)”.
•
When input terminal DFL has other function, the inverter may malfunction.
•
To enable this function, set the slide switch SW1 of HF-TM2 to ON.
(With the factory setting, slide switch SW1 is set to OFF to disable the function
)
•
If intelligent input terminal DFL is left unconnected, the cable connected to the terminal is
disconnected, or the signal logic is improper, the inverter trips due to emergency stop.
•
While power is supplied to the inverter, don’t switch the slide switch due to
prevention
the inverter failure. Be sure to operate the switch of HF-TM2 after confirmation of turning
off the power lamp on operator unit.
