Variable torque limit via process data

This additional function can be used to limit the torque in the operating modes (FCBs) permitted by the device firmware. The control word for the torque limit can also be used to deactivate the monitoring of speed and lag errors.

This additional function is activated under the basic settings via "Activate control word for torque limit".

The variable torque limit via fieldbus is only effective in the following drive functions:

• FCB 05 Speed control
• FCB 09 Position control
• FCB 12 Reference travel

If the "Use torque limits from profile value connection" parameter is activated, the variable torque limit also applies to the following drive functions:

• FCB 02 Stop default
• FCB 13 Stop at application limit
• FCB 14 Emergency stop
• FCB 26 Stop at user-defined limits

INFORMATION

In application mode "100: Jog mode – position controlled" (FCB 20), lag error monitoring cannot be deactivated. Therefore, when a torque limit is activated use application mode "101: Jog mode – speed controlled" (FCB 05).

INFORMATION

With a torque limit of 0%, the torque from the "Application limit - torque" is used.
