S120 - PT100 (5 pcs.) – winding/ bearings – how?

Hi,

what a standard solution for connecting resistance thermometers (PT100) from the motor (in stator winding 3 pcs. and 2 pcs. for rolling-contact  bearings, total 5 pcs.)

to Sinamoics S120 CU320 (6SL3040-0MA00-0AA1) and Motor Modules (Chassis Format, eg. 6SL3320-1TG37-4AA3).

at first I thought to connect them to the PLC (to analog modules, directly PT100 or through transmitters PT100/4..20mA),

but I only have one PLC and 20 pcs. Sinamics (20 pcs. motors and 5 PT100 on each motor, total 100pcs. PT100),

therefore, to increase reliability, I would like separately connect sensors from each motor to each Sinamics,

by default Motor Modules (Chassis Format, eg. 6SL3320-1TG37-4AA3) has one input for connecting

only one - Temperature sensor connection KTY84-1C130 / PT1000 / PTC (X41 EP terminal / temperature sensor connection),

but i need to connect 5 pcs.?

How best to do it, which module to use?

also measured temperature  I would like to transfer to the PLC ()

I don't know if Profinet telegram size is enough for additional data transfer (5pcs. temperatures).

You can use also TM Modules for Temperaturen evaluation 

For example TM150 ,  TM120

Hi,

regarding telegram length this should not be a problem. You can extend the telegram length in send direction to 28 Words. This should be enough.

Hi,

for Servo: 28 words

for Vector: 32 words

CU: 25 words

TM120/150: 5 words

TM120 not suitable because the module can be connected only 4 sensors (and we have 5 sensors) and TM120 supports connection only 2wire (PT100) (and we have 3wire sensors PT100).

TM150 I think it suitable, but

Do I understand correctly that TM150 can connect a maximum 6 pcs (PT100 3wire) (circuit attached)?

my cable length will be about 150m, and I'm worried that the measurements will not be correct.

I also consider the possibility use transmitters PT100 / 4..20mA,

we plan to install transmitters near the motor. 

which module has 5 analog input (4..20mA)?

Why in Sizer (V3.19) I can not choose TM120 (or TM150)?
