Operations

 

 

 

 

 

-The emergency stop function shuts off the inverter output (i.e. stops the switching operation of the main circuit elements) in response to a command from a hardware circuit via an intelligent input terminal without the operation by internal CPU software.

Note: The emergency stop function does not electrically shut off the inverter but merely stops the switching operation of the main circuit elements. Therefore, do not touch any terminals of the inverter or any power lines, e.g., motor cables. Otherwise, electric shock, injury, or ground fault may result.

-When the emergency stop function is enabled, intelligent input terminals 1 and 3 are used exclusively for this function, and no other functions can be assigned to these terminals. Even if other functions have been assigned to these terminals, these are automatically disabled and these terminals are used exclusively for the emergency stop function.

Terminal [4] function:

This terminal always serves as the a (NO) contact for the reset (RS) signal. This signal resets the inverter and releases the inverter from the trip due to emergency stop (E37.*).

Terminal [3] function:

This terminal always serves as the b (NC) contact for the emergency stop (EMR) signal. This signal shuts off the inverter output without the operation by internal CPU software. This signal makes the inverter trip due to emergency stop (E37.*).

Note: If intelligent input terminal 3 is left unconnected, the cable connected to the terminal is disconnected, or the signal logic is improper, the inverter trips due to emergency stop (E37.*). If this occurs, check and correct the wiring and signal logic, and then input the reset (RS) signal. Only the reset (RS) signal input from intelligent input terminal [4] can release the inverter from tripping due to emergency stop (E37.*). (The inverter cannot be released from the E37.* status by any operation from the digital operator.)
