Other unit functions via RS485 interfaces
In addition to process and parameter data exchange between PC, keypad and
MOVIDRIVE
®
B, the RS485 interfaces can also be used for the following functions:
• Master/slave operation
• IPOS
plus®
• Manual operation
4.4.1
Using RS485 interfaces for master/slave operation
The master/slave function shown in the figure below allows for implementing automatic
functions such as speed synchronization, shared load and torque control (slave). The
RS485 interface (X13:10/X13:11) or the system bus interface (CAN 1) can be used as
communication link.
P100 Setpoint source = Master SBus
or
P100 Setpoint source =
Master RS485
must be set on the slave. The process output data PO1 - PO3 (P870,
P871, P872) are automatically set by the firmware. A programmable terminal function
"Slave free run. "P60x binary inputs basic unit /P61x binary inputs option, it is possible
to separate the slave from the master setpoint and switch to local control mode.
*) DIØØ "/Controller inhibit" and the programmed binary inputs Enable, CW and CCW
must also receive a "1" signal.
TIP
For the slave, the process data P87x are automatically assigned as follows:
– PO1 = Control word 1
– PO2 = Speed or current in M-control
– PO3 = IPOS PO data
– PI1 = Status word 1
– PI2 = Speed
– PI3 = IPOS PI data
PI3 and PO3 are not used. They are available in IPOS
plus®
as required.
If a fieldbus card is plugged in the slave, only the parameter channel is available for the
output data. The master can read the automatically assigned process input data via
fieldbus.
