13.5.3 Wiring
The following figure shows the connection of V1000 inverter drives via RS485. Here the
individual inverter drives are connected via PROFIBUS cables and connected to the CPU
via a PROFIBUS connector to the PtP interface (Point-to-Point).
n A maximum of 8 inverter drives can be connected via Modbus RTU.
n For all connected inverter drives, parameter H5-07 must be set to 1.
n The serial line must be terminated at its end with a terminator. To activate it, you must
set switch S2 to ‘ON’ on the corresponding inverter drive.
– *) For a trouble-free data traffic, use a terminating resistor of approx.
120
W
at the CPU, such as the PROFIBUS connector from VIPA.
– Never connect the cable shield and the M5V (pin 5) together, due to
the compensation currents the interfaces could be destroyed!
