Enable/Disable Setpoint or Enable/Disable Operation Sinamics G120C

Hello, I'm currently working in a typical conveyor belt application with Sinamics G120C for moving the conveyor via profinet using telegram 352.

Wich is the best action to start/stop the movement of the motor conveyor?  

1. Start / Stop the motor with STW1.3 ( Enable/Disable Operation). Inmediately switch-off motor (suppress pulses). 
   • BAD: In this way the motor does a rapid stop, but I think that it doesn't follow the stop ramp. 
   • GOOD: Disable the pulses to motor and then the current it's ZERO
2. Start / Stop the motor with STW1.6 ( Enable/Disable Setpoint). Motor start and stop with ramps.
   • BAD: when disable the setpoint the motor goes to zero setpoint and the current is high
   • GOOD: The motor follows the stop ramp.

So, I would appreciatte what do you recommend based on your experience to start/stop the motor.

My vendor says that he uses the STW1.3 bit to start/stop the driver, but i think it's not the best option.

Thanks!

Why dont you use STW1.0 instead of 1.3 and 1.6. Make 1.3 and 1.6 always high. It will follow your ramp up and ramp down as specified. 

Yes, that is what I've done..

Thanks!
