PRM31: Open-circuit fault detection level
This parameter sets the sensitivity for detecting an open-circuit fault. The upper limit of
this parameter is 254. The sensitivity lowers as the parameter value increases. Leave this
parameter set to 255 if you want to disable this detection function.
Input range: 1 to 255
Default value: 255 (This function is disabled.)
PRM32: Alarm number output
When an alarm is issued, this parameter selects whether the alarm number is to be output
as a general-purpose output. When this parameter is set to 1, the alarm number is output as
a 5-bit binary signal through DO0 to DO4.
Input range: 0 or 1
Meaning: 0: No output
1: Output
Default value: 0

PRM33: Operation at return-to-origin complete
Selects the operation to be executed simultaneously with completion of return-to-origin.
A signal can be output as a general-purpose output indicating that return-to-origin has
been completed or to reset the program.
Input range: 0 to 3
Meaning: 0: Nothing is executed
1: DO4 is turned on
2: Program reset is executed
3: DO4 turns on after program reset
Default value: 2
* When this parameter is set to 1 or 3, DO4 is not affected by program reset (in other
words, DO4 does not turn off even when the program is reset). If you want to turn off
DO4 after return-to-origin is complete, use the program command to execute DO 4,0 or
manually operate the general-purpose output by using the TPB.
(See "7-4 Manual Control of General-Purpose Output".)
