9.4.2 Description of the interfaces and functions
A simplified 1axis 611A feed module is shown in block diagram 9-8. This com-
prises power module, control module with standard interface and analog set-
point interface for 1FT5 servomotors.
Additional control modules with analog, digital and PROFIBUSDP interface
––> refer to Section 5.
FR+
+ 24V enable voltage for the internal enable signals
Pulse enable / start inhibit
When terminal 663 is energized, this has a double function:
S The pulse enable and inhibit act on a specific axis after 1 ms or on a module
for twoaxis modules via an optocoupler input.
S The start inhibit, terminal 663 opencircuit, acts with an approx. 40 ms
delay after terminal 663 is inhibited, as a result of the dropout delay of the
start inhibit relay.
The start inhibit supports all of the safetyrelevant functions, refer to
Section 9.5.
For pulse inhibit/start inhibit, the drives coast down unbraked.
The 1axis and 2axis 611D modules with digital and 611U with PROFIBUS
interface have, beyond this, also an axisspecific pulse enable. It is
controlled through NC/PLC interface signals via the digital drive bus or via the
PROFIBUSDP interface. The signals act with delay, corresponding to the
particular cycle time.
Notice
The pulse inhibit using terminal 663 for control modules with Order Nos.
6SN11180AA110AA0, 6SN11180AD110AA0 and 6SN11180AE110AA0
(old FD types) only become active approx. 40 ms after actuation after the relay
drops out.
For type 6SN11180....0..1, 6SN11180DM2.0AA0, 6SN1121.......1 and
6SN1122.......1, (new types), the pulse inhibit becomes effective approx. 1
ms.
The different times must be observed. The older modules, with the delayed
pulse inhibit after approx. 40 ms may not
be used for the circuit examples, Sec-
tion 9.7 , external speed monitoring = 7 ; armature shortcircuit braking = 9 and
power contactors in the motor circuit =10.
