Basic Functions

 Angle - Displays values over recorded angle.

 Pos. Angle - Displays values over positive angle. All angle movements are positive, i.e. the angle

of the cycle is always increasing, even if the bolt was moving backwards.

If Advanced view is enabled it is also possible to select the following for the second angle channel:

 Angle 2

- Displays values over recorded second angle channel.

 Pos. Angle 2

- Displays values over positive second angle channel. All angle movements are

positive, i.e. the angle of the cycle is always increasing, even if the bolt was moving backwards.

For all quantites except angle and time, there may be gaps in the recorded values. For example when

spindle functional test is performed, torque values are not recorded. When the torque curve is displayed

on the graph, a small gap in the curve is shown when the spindle functional test was performed. Another

example is Gradient values which are only recorded when the restriction Gradient is active.

If Torque (or Pos. Torque) is selected, the torque unit displayed is the one used when the trace was

recorded. If many traces are displayed with different torque units, the torque unit for each trace can be

found in the identity list. This list is displayed by clicking on the button Identity>>.

The second torque and angle channels are only available when the following conditions are true:

 Equipped on spindle and marked as enabled in the spindle setup.

 Selected as included in the general program settings.

Note! The actual second Angle and Torque channel used is the channel that is not configured as

Monitoring channel (regular Angle and Torque channels).

Note! Collection of Secondary Torque and Angle channels in the trace must be enabled for each program,

this is described in chapter Program Settings.
