6es7332-5hf00-00ab0

I have analog output card 6es7332-5hf00-00ab0 and I only use two channels 

the output command is +/- 10V .

in siemens manual I should connect the pin 6 to the "M ANA" and to 0 v DC. but I will work from -10 to +10.

and I have measure voltage when I work on negative side. Pin 6 become the positive and pin 3 is zero.

and when work on positive side. Pin 3 is the positive and pin 6 is zero.

so should I connect like the manual or not.

NOTE:-

I'M USING THIS OUTPUT COMMAND TO CONTROL PROPORTIONAL VALVE AND IT SHOULD BE LIKE THE PHOTO NO .2 

Did you ckeck the scalling function of your analog outputs ?

Is your analog output card redundantly connected or not ?

MOHAMED,

I don't have redundant. and I check the scaling it's okay. and working fine.

simply my problem,

when I forced 13824 on QW I have +5 between pin 3 and pin 6. ( PIN 3 is 5 V and Pin 6 is zero V)

and when  I forced -13824 on QW I have -5 between pin 3 and pin 6. (PIN 6 is 5V and Pin 3 is zero)

and this is okay but my problem is I want pin 6 to be always zero and Pin 3 to change from +ve to -ve

 Hello Amr,

I think there is no contradiction between connection in SIEMENS manual and what you want to do.

Connecting Mana to 0 volt means it is connected to a reference voltage, so in case of negative voltage values (-10 volt as example) the voltage of pin 3 will be less by 10 volts than the voltage reference connected to pin 6

Please refer  attached sheet & carry out connection. ( 2 wire output)

While doing so select analog module out put as +/- 10V with proper selection (A, B, C, D)

Dear Ibrahim,

I know Pin 3 will be less than pin 6 by 10 voltage. but again my question is how much pin 6 's voltage will be?

I know there will be -10 v between pin 3 and pin 6, but what is Pin 3 voltage, and pin 6 voltage. i don't ask about the voltage difference.

 what is the proper selection (A,B,C, D) you are talking about.

there is no hardware selection in this card. I just configured it in H/W configuration in simatic manager

 Hello,

You can never know the potential of a point even 0 vdc is stated only as reference but in all datasheets you can see them talking about voltage difference not the voltage of each point

There is no meaning for talking about the potential of a certain point without telling an about the reference from which you measure this potential
