DB390x
DBX1.2
Axis ready
Signal(s) from axis / spindle (NCK → PLC)
Edge evaluation: No Signal(s) updated:
Meaning The signal is fed to the PPU, to which the axis is physically connected.
Signal state 1 Axis is ready.
Signal state 0 Axis is not ready.
This
status is
set if the channel, the mode group or the NCK have generated
the alarm "Not ready".

DBX1.3
Follow-up mode active
Signal(s) from axis / spindle (NCK → PLC)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 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for the drive has been withdrawn (either by the PLC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.
Signal state 0 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.
Special cases, errors, ... Notice:
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).

DBX1.4
Axis / spindle stationary (n < n
min
)
Signal(s) from axis / spindle (NCK → PLC)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 The actual velocity of the axis or the actual speed of the spindle lies under
the limit defined using the MD36060.
