Instantaneous shutdown, pulse enable ––> refer to Fig. 8-5
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or a fault signal, then the ready signal is withdrawn at the NE module; this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.
Delayed shutdown pulse enable ––> refer to Fig. 8-6
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 If the signal is withdrawn at the NE module, termi-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 6.3).
–
The ex24V 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.
