Functions
Start drives
The two–channel stop circuit in front of safety switching device –K11 must be
closed–via key–actuated switch –S11 and the EMERGENCY STOP circuit,
=2–K21. Contactor –K11 is energized (switched in) with ”monitored start” using
pushbutton –S12 start and closed feedback circuit. It latches. Terminal 65 con-
troller enable and terminal 663 pulse enable are energized
The drive is traversed and shut down in a controlled fashion using the NC pro-
gram
Stop drives
The switching device–K11 is opened via key–actuated switch –S11 or an
EMERGENCY STOP. The instantaneous contact de–energizes terminal 65
”controller enable” and the drive is braked along the current limit. Terminal 663
is de–energized, which activates the start inhibit via the delayed drop–out con-
tact –K11.
Start inhibit – monitoring
The start inhibit – monitoring, terminals 35–36 is effective in the EMERGENCY
STOP circuit of contactor =K2–K21.
Under normal operating conditions, when the drive is being stopped, the NC
contact AS1–AS2 of the start inhibit relay should first be closed before the NO
contact of contactor –K13 opens. To realize this, the contactor coil –K13 must
be provided with a diode to extend the contactor drop–out delay. For an erro-
neous start inhibit, the monitoring circuit opens and shuts down the complete
drive group via the line contactor.
The start inhibit is cyclically and actively monitored after every stop.

Circuit example =4 “Powering up/powering down/stop-
ping drives in an emergency; start/stop/safe standstill”
Application
Drive group comprising NE module, MSD module for 1PH7 motor and three FD
modules 611A control modules with standard interface and analog setpoint in-
terface for 1FT5 motors. The circuit =4 is the basis circuit for the drive–related
control, e.g. a machine tool. The control can be expanded in a modular fashion
using the following circuit components =5 to =10 with the necessary interlocking
and monitoring circuits and the application–specific supplements/options. This
means that it can be individually adapted to the particular application.
Functions
Drives on (NE module)
S Key–actuated switch –S21 control on.
The power–off circuit in front of the EMERGENCY STOP safety switching
device –K21 must be closed using the following conditions:
