Circuit example, 611 digital with SINUMERIK 840D

A circuit example SIMODRIVE 611 digital and SINUMERIK 840D with the drive–
related control for a machine/plant, based on the circuit examples in Fig. 8-23
with 611 in its principle form, is shown in Section 8.7.

Circuits with 611 digital

The digital control units 611 digital have a digital setpoint and actual position
value interface to the 840D or 810D NC control systems. The boards are avail-
able as either 1–axis or 2–axis modules with High Performance or High Stan-
dard control.
Further, the units differ in the connection version:

For a description of the interfaces of the 611 digital control units
––> refer to Chapter 5.
All of the NC control communications to the 611D drive modules are realized via
the digital drive bus. The axis–specific controller and pulse enable signals as
well as the operating and monitoring signals are placed on the digital drive bus
via NC/PLC interface signals.
The terminal 663 pulse enable/start inhibit for the 611D modules is provided on
a module–for–module basis. The axis–specific pulse enable signals received
via the drive bus are logically ANDed with the signal state at terminal 663.
Control with
The NC control with the integrated PLC–CPU SIMATIC S7–300 is accommo-
SINUMERIK 840D dated in a 50 mm wide housing that is compatible to the SIMODRIVE drive
modules.
The control is integrated in the SIMODRIVE 611D drive group and can be ex-
panded up to 31 axes. It is located between the NE module and the first drive
module in the drive group. The power supply for the internal control voltage is
derived from the NE module power supply via the equipment bus. The NC
ready signal acts on the ready signal terminal 72–74 of the NE module via the
equipment bus.
