(5) Motor temperature detection signal (when using a dedicated vector motor with thermistor
and FR-A7AZ)
The change applies to the December 2010 production or later.
When using a dedicated vector motor with thermistor (SF-V5RUT/A) and FR-A7AZ, motor temperature detection is
available. When motor temperature exceeds the detection level, motor temperature detection signal (Y55) is output. (Set Pr.
407 Motor temperature detection filter  "9999")
Set "55 (positive logic)" or "155 (negative logic)" in the following parameters to output the motor temperature detection signal
(Y55) when motor temperature exceeds the detection level.
