The SINAMICS G110 inverters can be operated using the following modes:
Terminal
This mode provides a simple method of controlling the inverter using switches and
a potentiometer and is only available on the Analog variant. The commissioning for
this mode is described in Section 3.3.1 on page 35. No advanced commissioning is
possible!
Serial
The USS protocol can be used either via the RS232 or via the RS485 interface to
commission, parameterize and run the inverter. The USS-RS485 interface is only
available on the USS variant (see Section 3.3.1) and can be directly connected to
an inverter network or a USS master such as a PLC. The USS-RS232 interface
can be used with both variants but requires the optional ‘PC to Inverter Connection
Kit’.
The prerequisite for using the serial interfaces is that the baud rate and the bus
address of the inverter must be established prior to any parameterization or
commissioning.
For further details see the following parameters (details of the default settings given
in Section 3.3.1.):
¾
P2010 – Baud rate
¾
P2011 – Bus address
¾
P2012 – PZD Length
The parameters can be changed by using the optional BOP. A change via the USS
protocol is also possible, however, this requires the USS master to reconnect with
the new settings.
The Parameter List provides information about further parameters and settings for
the USS telegram.
The default values of P2010, P2011 and P2012 are shown in Table 3-2 on page
36.
Set P0719 = 55 or set the command source P0700 = 5 and the frequency setpoint
P1000 = 5 for complete inverter control when in SERIAL mode.
BOP
If the factory default settings of the inverter are not suitable for your application, the
inverter can be modified for the required application using the optional Basic
Operator Panel (BOP).
The BOP allows the user direct access to the parameters of the SINAMICS G110
inverter.
With the BOP attached to the inverter, the user can perform the following functions:
¾
Change parameter values
¾
Monitor specific parameters
¾
Clone parameters from one inverter to another inverter. This is of great value
when dealing with multiple inverters as in the case of the USS variants (see
Section 3.4.7 on page 49).
The BOP can be used to configure several SINAMICS G110 inverters. This is
accomplished by using the BOP to set the required parameters and once the
process is complete, then the BOP can be removed and used on another inverter.
The BOP contains a five-digit display that allows the user to read and change
parameter values.
