Diagnosis & Eliminar
Independently of the kind of temperature determination
check:
1. P0604 motor temperature warning threshold
2. P0625 motor ambient temperature
If (P0601 = 0 or 1) Check the following:
1. Check if name plate data are correct (if not perform
quick commissioning)
2. Accurate equivalent circuit data can be found by
performing motor identification (P1910=1).
3. Check if motor weight (P0344) is reasonable.
Change if neccesary.
4. Via P0626, P0627, P0628 the standard
overtemperatures can be changed, if the motor is
nota Siemens standard motor.
If (P0601 = 2) Check the following:
1. Check if temperature shown in r0035 is reasonable.
2. Check if the sensor is a KTY84 (other sensors are
not supported)
Check the following:
1. Ambient temperature must lie within specified limits
2. Load conditions and duty cycle must be appropriate
3. Fan must turn when drive is running
Check the following:
1. Ambient temperature must lie within specified limits
2. Fan must turn when drive is running
3. fan intake air has to be without any resistance
Warning can be masked.
Stop inverter and then
1. Check encoder fitted.
2. Check connections between encoder and inverter
3. Check encoder not faulty (select P1300 = 0, run at
fixed speed, check encoder feedback signal in
P0066)
4. Increase encoder loss threshold in P492
