Inputs
The drive halt function is used to bring an axis to standstill with defined
acceleration and jerk (see functional firmware description).
The input drive enable (RF) activates the drive with a 0-1 edge.
Note:
If the inputs are controlled by a power supply other than the
DC24 volt supply of the DKC, then the reference lead of the
other power supply must be connected to X1.2 (0 V).

The Bb contacts opens:
•
if control voltage for DKC is not applied
•
if 24 volts not present at the emergency stop input when the E-stop
function is activated (depends on parameterization, see function
description).
•
With an error in the drive (depends on parameterization, see functional
firmware description: "Power off on error").
WARNING
Damage possible if Bb contact not connected !
The ready to operate contact Bb acknowledges the drive
is ready for mains voltage.
⇒
Integrate Bb contact as per "Control Circuits for the
Mains Connection" (see Project Planning manual).
⇒
The evaluation of the Bb contact by a PLC may not
cause any operating delay of more than 10 ms.
