Variable torque limit Q1
This additional function activates the utilization of the control word for the variable torque limit Q1. The control word can also be used to deactivate the speed monitoring and lag error monitoring.
The additional function can be activated in the [Basic settings] parameter group under "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 Positioning control
- FCB 12 Reference travel
If the "Use torque limits from profile value connection" parameter (Index 8563.2, bit 0 and 8564.2, bit 0) is activated, the variable torque limit also applies to the following drive functions:
- FCB 02 Stop standard
- FCB 13 Stop at application limit
- FCB 14 Emergency stop
- FCB 26 Stop at user-defined limits
INFORMATION
In jog mode – position controlled (100) operating mode, lag error monitoring cannot be deactivated. Therefore, use jog mode – speed-controlled (100) operating mode when the torque limit is activated.
Specification of the torque limit of 0% via process data
The setting of the "Use torque limit from profile value connection" parameter determines how the torque limit is interpreted via process data.
- Setting "Off" (default value):
- A torque limit of 0% corresponds to a motor torque of 0%. The "Minimum torque limit" parameter is also taken into account.
- Setting "On":
- A torque limit of 0% corresponds to the torque from the application limit. When the torque limit is > 0%, the minimum torque limit is taken into account.
