Direction variable
Shows the effective cam direction of the most recent MC_CamSwitch or
MC_CamSwitchTime command. The variable is not changed in the following
"MC_CamSwitch" and "MC_CamSwitchTime" modes:
• Value = 1 (cam locked)
• Value = 4 (cam permanently enabled)
Value Function
1 Positive direction of action
2 Positive and negative (i.e. the effective direction is irrelevant)
3 Negative direction of action
4 The current sense of direction of the axis is the effective direction
OnPosition variable
This variable indicates the current ON position.
OffPosition variable
Indicates the current OFF position of a position-controlled axis.
Duration variable
Indicates the pulse duration of a time-based cam. The physical unit corresponds
with the physical unit of the "time" at the corresponding axis.
Delay variable
Indicates the current offset (derivative action time) of the ON/OFF times.
Value < 0: Advanced switching
Value > 0: Delayed switching
Hysteresis variable
Indicates the current values of the hysteresis.
