Installation and execution specifications for control cabinets
For the form of the control cabinets for the installation of drive components, the following
important specifications must be observed when selecting:
● DIN EN 60439-1 (VDE 0660 Part 500), low-voltage switchgear combination
● DIN EN 60204-1 (VDE 0113 Part 1), electrical equipment for machines, safety
● DIN VDE 0106 Part 100, protection against electrical shock
● EMC regulations (89/336 EEC) and low-voltage regulations (73/23/EEC)
● The associated requirements placed on the environmental conditions (e.g. housing
degree of protection IP.., installation altitude, ambient temperature, etc.)
7.2 7.2 Functional description of the typical circuit diagrams
The following section uses typical circuit diagrams to illustrate and describe in detail the
individual applications and functions of the drive control.
First, the connection of the system to the line voltage and the the 24 VDC power supply is
discussed. Simple control connections using the PROFIBUS interface or digital interface to a
higher-level PLC are also described. Building on the general switching notes, safety-oriented
functions are described in additional typical circuit diagrams. The PLC controller handles the
coordinated execution of the drive control, but does not have any safety-related function.
Layout of the typical circuit diagrams
● Circuit manual group =1
Line infeed and creation of the 24 VDC power supply
● Circuit manual group =2
Drive group with line contactor, Active Line Module, without safety functions
● Circuit manual group =3
Drive group without line contactor, Smart Line Module without DRIVE-CLiQ connection,
without safety functions, motor protection with Voltage Protection Module (VPM).
● Circuit manual group =4
Activate/deactivate/stop drives or drive group in an emergency (emergency stop) using
drive-integrated safety function
● Circuit manual group =5
Drives start / stop / safe standstill (axis-specific) using drive-integrated safety function
● Circuit manual group =6
Drives or drive group on/off; stop in an emergency (emergency stop); safety using drive-
integrated safety function of the SINUMERIK 840D sl; ET 200S distributed peripherals.
The following section does not further discuss the setpoint and actual value interface and the
user's machine control. This means they are shown only in general form.
