S The interlocking circuits of the subsequent expansions to circuits =7 to =9
are jumpered.
S Contactor –K25 energized and contact =A1–A25/1–2 NC ready is closed
The power–on conditions are almost comparable with those of circuit =2.
The ready signal of the MSD module PLC–E15 must be additionally logically
combined with the ready signal of the NE module PLC–E11 in the PLC.
S Pushbutton –S23, drives on
Contactor –K21 is energized and latches. Initially, only the NE module is
powered up. After the DC link has been pre–charged, the line contactor is
closed. As long as there are no fault messages at the NE module and at the
FD modules (switch, ready/fault message is set to fault message), the ready
signal is output.
Start drives (drive modules)
S The NE module must be powered up. The stop circuit in front of the safety
switching device –K31 must be closed. The interlocking circuits of the sub-
sequent expansions to circuits =5 and =7 are jumpered
S When the feedback circuit is closed, contactors –K31 with expansion device
–S32 and contactor –K35, –K33, –K36 close and latch through pushbutton
–S32, start drives (monitored start).
S At the same time, terminal 63, central pulse enable, terminal 64 ”drive ena-
ble” at the NE module and terminal 663 ”pulse enable” are energized for the
drive modules which withdraws the start inhibit signals.
NC program start/stop
S Pushbutton –S29/–S28
The axis–specific controller enable signals are activated via pushbutton –
S29 NC program start and the machining program is started. The drives are
brought to a controlled standstill at the end of the program or using the push-
button –S28 stop.
Stop drives
S The drives, assuming that these still have not been shut down via the NC
program are braked down to standstill as fast as possible along the selected
current limit via the two–channel pushbutton –S31 stop drives.
S The instantaneous contact of contactor –K31 de–energizes terminal 64
drive enable. After the drives come to a standstill, terminal 663 is de–energi-
zed and the start inhibits are active via the delayed drop–out contacts of
safety switching devices –K32 and –K35.
S The stopping times are adapted to the different braking times of the MSD
and FD drives and must reliably and safely covers these, e.g. MSD 5 s ; FD
0.5 s.
