5.8.12 MAC00-FP2 - How to connect the RS232 interface
The illustration below shows how to connect the MAC00-FP2 directly to a PC COM
port. The drawing is based on standard cables from JVL, type WG0402, WG0410 or
WG0420. See also
Accessories, page 448 for a complete list of cables and connectors.
If the MAC motor is connected to the same RS232 line as other motors, the terminal TX-
PD should only be connected at one of the motors. If one of JVL’s standard RS232 cables
(RS232-9-1 or -n) is used between the
DSUB connector shown and the PC com port,
the RX and TX pins must be swapped since they cross in these standard cables.
5.8.13 Operation with dual supply for emergency situations
In many applications it is intended that positional data and other setup information is re-
tained during an emergency situation. It is however also required by law in many coun-
tries that the main power for energizing the motor is removed in such a situation.
To meet both of these requirements, the MAC motor equipped with a MAC00-FPx
module offers a secondary supply input called “CV”. If the main supply at the P+ terminal
is removed, the internal control circuitry can be kept “alive” by maintaining a supply at
the “CV” terminal.
