Motor Temperature Detection Signal - Mitsubishi Electric FR-A7AZ 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 of the inverter for details.)
⋅ Pr.313 to Pr.319 DO0 to DO6 output function selections (Refer to the Instruction Manual of FR-A7AY for details.)
⋅ Pr.320 to Pr.322 RA1 to RA3 output function selections (Refer to the Instruction Manual of FR-A7AR for details.)
Use the following parameter to adjust the temperature to output the motor temperature detection signal
(Y55).
Parameter Number
750 * Motor temperature detection level
* Read/write is enabled when using FR-A7AZ.
REMARKS
⋅ The motor temperature detection signal is not available when Pr. 407 = "9999".
