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 [1] function –
This terminal always serves as the “a” (N.O.) contact for the reset
[RS] signal. This signal resets the inverter and releases the inverter from the trip due to
emergency stop (error code E37).
Terminal [3] function –
This terminal always serves as the “b” (N.C.) 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 (error
code 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 [1] can release the
inverter from tripping due to emergency stop (E37). The inverter cannot be released from the
E37 trip status by any operation from the digital operator.
Note 1:
When function [RS] (code 18) is assigned to the input terminal, “a/b (N.O./N.C.)”
selection is always 00 (N.O.).
Note 2:
When terminal setting C003 is [EMR] (code 64), terminal setting C013 is always
01 (N.C.).
Note 3:
If function [RS] (code18) has been assigned to an intelligent input terminal other than
intelligent input terminals [1] and [3] before slide switch SW1 is set to ON, the input
terminal setting for that terminal is automatically changed to NO (no function
assigned) when slide switch SW1 is set to ON. This prevents any duplication of
terminal functions. Even if slide switch SW1 is subsequently turned OFF, the original
function setting for the terminal will not be restored. If necessary, the original
function will have to be reassigned to the terminal.
Example –
If slide switch SW1 is set to ON when function [RS] (code18) has been
assigned to input terminal 2 (by terminal setting C002), terminal setting C002 is
changed to NO (no function assigned), and function [RS] (code 18) is assigned to
input terminal 1 (by terminal setting C001). Even if slide switch SW1 is subsequently
