228 List Manual (LH11), 01/2016, A5E33839529
Description: Sets the fixed, lower torque limit.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p1520, p1522, p1523
Danger: Positive values when setting the lower torque limit (p1521 > 0) can result in the motor accelerating in an
uncontrollable fashion.
Notice: A BICO interconnection to a parameter that belongs to a drive data set always acts on the effective data set.
Note: The torque limit is limited to 400% of the rated motor torque. When automatically calculating the motor/closed-loop
control parameters (p0340), the torque limit is set to match the current limit (p0640).
Description: Sets the signal source for the upper torque limit.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p1520, p1521, p1523
Danger: Negative values resulting from the signal source and scaling can cause the motor to accelerate in an uncontrolled
manner.
Description: Sets the signal source for the lower torque limit.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p1520, p1521, p1522
Danger: Positive values resulting from the signal source and scaling can cause the motor to accelerate in an uncontrolled
manner.
Description: Sets the scaling for the upper torque limit.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Notice: A BICO interconnection to a parameter that belongs to a drive data set always acts on the effective data set.
Note: This parameter can be freely interconnected.
The value has the meaning stated above if it is interconnected from connector input p1528.
