Axis ready
Signal(s) from axis / spindle (NCK → PLC)
Signal(s) updated:
The signal is fed to the PPU, to which the axis is physically connected.
Axis is ready.
Axis is not ready.
This status is set if the channel, the mode group or the NCK have generated
the alarm "Not ready".
Follow-up mode active
Signal(s) from axis / spindle (NCK → PLC)
Signal(s) updated: Cyclic
The control signals that the follow-up mode for the axis / spindle is active.
Prerequisites for this are:
● The controller enable for the drive has been withdrawn (either by the PLC
with "controller enable " = 0 signal or inside the control for faults).
● Follow-up operation is selected (either by the PLC with IS "follow-up
operation" = 1 signal or in the control, e.g. when withdrawing the
controller enable from an axis that is moving)
The position setpoint continually tracks the actual value while the follow-up
mode is active. The standstill and clamping monitoring are not active.
The control signals that follow-up mode for the axis / spindle is not active,
i.e. the above mentioned prerequisites are not fulfilled.
Zero speed and clamping monitoring are active.
In the "Hold" state, the IS "Follow-up mode active" has a 0 signal.
A delete distance-to-go is triggered internally in the control at the transition
from "Follow up" to "Hold" (IS "Follow-up mode" = 0) or in the closed-loop
control mode (IS "Controller enable" = 1).

Function Manual, Special Functions; M3/T3
Axis / spindle stationary (n < n
Signal(s) from axis / spindle (NCK → PLC)
Signal(s) updated: Cyclic
The actual velocity of the axis or the actual speed of the spindle lies under
the limit defined using the MD36060.
