This restriction checks the gradient and if it is outside the limits the tool is stopped immediately and the program jumps to the end of the program.

Parameter

Description

Gradient Angle Window

Specifies Angle Window:

  • For Hard Joint: Angle Window = 1 deg.

  • For Soft Joint: Angle Window = 20 deg.

  • Manual: Manually set Angle Window.

Angle Window

Available when Gradient Angle Window is set to Manual. Must be > 0 and <= 100.

Trigger Torque

Must be > 0 and < Tool MaxTorque.

Damping

Frequency in which the gradient is being calculated. Must be > 0 and < 100 and < Angle window.

Minimum Limit

Must be >= -100.

Maximum Limit

Must be > -100 and > Low limit.

Torque Filter Type

The type of the filter:

  • None: No filtering of the torque is used. The raw values are used as-is in the gradient calculation.

  • Five-point: The torque value used in the calculation are filtered using a sliding average filter over 5 torque samples.

  • Low pass: The torque values is filtered with a simple discrete Infinite Impulse Response filter.

  • Sliding Average: The torque values used in the calculation are filtered using a sliding average filter over a Number of Samples specified by the use.
