Dears,

I am using Sinamic S130/150 in which required to make the motor to go OFF 3 control immediately when on command is withdrawn, for that I made a logic to control VSD via Profibus DP) telegram 352 -PZD 6/6). when a command is given it deenergises the OFF3 bit as well as energise OFF 1 bit, however, it looks like still take OFF1 bit as a high priority as the OFF1 ramp up timer =10s while OFF3 timer only =1s.

Can anyone suggest how can I make OFF3 bit disengage before OFF1 bit energise, although I can modify the logic through a timer or is any way to set up in the VSD?

B/R to all

OFF3 has higher  priority as OFF1.

So if OFF1 is active and you give OFF3, you will have the faster ramp.

Yes, OFF1 is the bit 0 and OFF3 is bit 2 of the control word.

For example, I give Bit 0 =1 and Bit 2= 1(OFF3 is fail safe mode) to active OFF 1 normal stop and then give Bit 0 =1 and Bit 2 = 0 to wish have a fast stop function.

BTW, how can I check whether OFF1 active or OFF3 active or both are active through events log.

Thanks.

Next time I am going to monitor that bit.

Just wondering any way I can find OFF 3 bit active from Events Logs instead.
