SIMOVERT MASTERDRIVES
Fig. 9-47 shows the digital input assignments used in this example
The assignment of functions to individual terminals used here is
arbitrary. The BICO technology (connector/binector technology) allows
virtually any terminal wiring to be implemented.
Terminal 8 is connected by means of the following parameter setting to
the OFF1 command in basic unit control word 1, which also actuates
the inverter enable in this example (the square brackets indicate the
relevant pages in the function diagram):
Terminal 5 is assigned to the "acknowledge fault" function (basic unit
control word 1)
Terminal 7 has a dual assignment:
♦ In homing mode you use it to define the "jog forwards" signal
[J_FWD], which starts the homing procedure:
♦ In MDI and synchronization modes you use it to specify the start
command [STA] used to start a movement (see manual /1/ "Motion
Control for MASTERDRIVES MC and SIMATIC M7", "Control and
checkback signals" chapter).
Terminal 6 has a dual assignment:
♦ In homing mode, the rough pulse is expected from the home
position cam or proximity switch (BERO) acting on the position
sensing system (see also MD45 in the "Machine data input"
section):
