3.3.1 Factory Settings
The inverter has already been programmed at the factory for standard V/f
applications on a Siemens standard four-pole 3-phase induction motor, that has
the same power rating as the inverters.
Controlling the speed of the motor is accomplished by connecting the analog inputs
on the analog variant (switches and the potentiometer are not supplied with the
inverter) or via the RS485 connections on the USS variant as shown in Figure 3-3
below.
Figure 3-3 Basic operation – Analog and USS Variants
The inverter can be used with its default settings for a wide range of applications.
The default settings are shown in Table 3-1 (Analog variant) and Table 3-2 (USS
variant). The terminal layout is shown in Figure 3-3 above.
Note
The motor base frequency might have to be changed as described in the previous
section on page 34.
