Inverter output shutoff
The inverter output can be shut off with the MRS signal. The logic of the MRS signal can also be selected.
*1
Refer to
for the details of the X10 signal.
Output shutoff signal (MRS signal)
• When the Output stop (MRS) signal is turned ON while operating the inverter, the inverter output is instantaneously shut
off.
• To input the MRS signal, set "24" in any parameter from
Pr.178 to Pr.189 (Input terminal function selection)
to assign
the function.
• The response time of the MRS signal is within 2 ms (except for the FR-E800-SCE).
• The MRS signal is used in the following cases.
MRS signal logic inversion (Pr.17 = "2")
• When
Pr.17
= "2 or 3", the input specification of the MRS signal is changed to normally closed (NC contact). The inverter
will shut off the output when the MRS signal is turned OFF (when the contact is opened).

Application
Description
To stop the motor using a mechanical brake (e.g.
electromagnetic brake)
The inverter output is shut off when the mechanical brake operates.
To provide interlock to disable the motor operation by the
inverter
With the MRS signal ON, the motor cannot be driven by the inverter even if
the start signal is input to the inverter.
To coast the motor to a stop
When the start signal is turned OFF, the inverter decelerates the motor to
a stop in the preset deceleration time, but when the MRS signal is turned
ON, the motor coasts to a stop.
