As stated on the previous page, MX2 inputs 3 and 4 become dedicated safety inputs once
the [middle] DIP switch SF SW1 is turned ON.
Similarly, with the [right-most] DIP switch EDM SW1 turned to the ON position, output 11
becomes a dedicated EDM (External Device Monitor) output for use with the external
safety monitoring relay.
Operation;
With the E-stop button in its “released” position and the reset switch “open”, the MX2 will
run as normal.
As soon as the E-stop button is pressed, the MX2’s power outputs (to the motor) are
instantly ‘cut’. Please bear in mind that depending on the application, this may cause the
motor to coast to a stop. In some cases, it may be preferable to perform a controlled stop
of the motor (using the inverter’s DC injection braking) before removing the power.
The MX2 will display an “E37.
□
” error code to indicate that a safe stop has occurred.
Once the E-stop is released and the RESET button has been pressed, the MX2 will revert
to normal operation.
Please be aware that it could instantly start again if the command inputs and frequency
reference remain set.
