• The bus cable between the master device and the drive must be
connected correctly. This includes the necessary termination resistors and
(for 12 MBd) the terminating network.
• The bus cable must be screened and the screen must be connected to the
housing of the cable connector.
• The PROFIBUS master must be configured correctly so that
communications can be realized with a DP slave using PPO type 1 or PPO
type 3 (only PPO type 1, if the PPO type cannot be configured via remote
operator control).
• When using COM ET software with a SIMATIC S5, the correct type
description file must be used, so that an IM 308B/C can be configured as
bus master. When using the Simatic Manager for an S7, the Object
Manager must be loaded.
• The bus must be operational (for a SIMATIC module, the operator control
panel switch must be set to RUN).
• The bus baud rate must not exceed 12 MBd.
• The PROFIBUS Module must be correctly fitted to the inverter and the
inverter must be powered up.
• The slave address for the drive (parameter P918) must be set so that it
corresponds to the slave address configured at the PROFIBUS master,
and must be uniquely defined on the bus.
Installation should be in conformance with EMC directives and regulations (this is
described in detail in the operating manuals for the drive and the PLC).
