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).
* Read/write is enabled when using FR-A7AZ.
