Motor Temperature Detection Signal - Mitsubishi Electric 800 Series Instruction Manual

6.3.5

Motor temperature detection signal

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.
• Pr.190 to Pr.196 Output terminal function selection (Refer to the Instruction Manual (Detailed) of the inverter for details.)
• Pr.313 to Pr.319 DO0 to DO6 output function selections (Refer to the Instruction Manual of FR-A8AY for details.)
• Pr.320 to Pr.322 RA1 to RA3 output function selections (Refer to the Instruction Manual of FR-A8AR for details.)
