Mitsubishi Electric FR-A5NR Instruction Manual page 37

COMPUTER LINK FUNCTION
CAUTION
1. If the FR-HC is connected, if the inverter operation enable signal (X10) is not assigned when
the FR-HC is used (Pr. 30 = "2") or if the PU operation interlock signal (X12) is not assigned
when the PU operation interlock function is set (Pr. 79 = "7"), this function is also used by the
MRS signal and therefore the MRS signal is only valid for the external terminals, independently
of the Pr. 338 and Pr.339 settings.
2. Pr. 180 to Pr. 186 (input terminal function selection) differ in function between inverters. For
details, refer to the Inverter Instruction Manual.
3. The orientation command requires the FR-A5AP and FR-A5AX options.
4. When the MRS signal is assigned for both Computer and External, the output halt command is as
indicated in the following table.
