8.3 Axis expansion using a monitoring module
S Instantaneous shutdown, pulse enable ----> refer to Fig. 8-7
The ready/fault signal at terminals 72--73.1 of the NE module act directly on
the pulse enable, terminal 63 at the monitoring module. If there is a line fault
or a fault signal, then the ready signal is withdrawn at the NE module; this
means that after the drop--out time of the ready relay, the pulses of the
drives after the monitoring module are inhibited and these drives "coast
down".
This interlock cannot be used, e.g. for a power failure concept -- and also it
can disadvantages with respect to other applications when compared to a
delayed shutdown.

Terminal 63 at the monitoring module is also only enabled via the ready/fault
signal at the NE module. If the signal is withdrawn at the NE module, termi-
nal 63 is however only inhibited via time relay--KT with drop--out delay.
This means, for example, for a line fault or a fault signal at the NE module,
under certain secondary conditions, the drives can be even more quickly
braked:
-- When braking, the DC link voltage must remain within the minimum and
maximum monitoring limits (refer to Chapter 6.2).
-- The external +24V power supply must maintain the enable signals of
terminals 65, 663.
-- For 611 digital drive modules, the internal enable signals must be main-
tained via the digital drive bus of the SINUMERIK 840D, 810D or for
SIMODRIVE 611 universal, communications must be kept via
PROFIBUS DP.
