The following examples show two practical applications for the
second parameter set.
Example 1
Roller conveyor with rotary table:
• Motor M1 (0.75 kW) drives the rollers on the rotary table and
transports the goods further.
• Motor M2 (1.5 kW) rotates the table for the alternating
acceptance of goods from two feed lines.
For alternating operation (rotary movement “exclusive or” of the
transport rollers) on the rotary table, a frequency inverter for the
largest connected load (MMX34AA4D3…) was selected.
The different rating data of the motors were set in the parameter
groups P7 (for motor M1) and P14 (for motor M2). The second
parameter set (P14) is activated here as an example via digital
input DI6 (P3.27 = 6).
The change between the two motors is implemented in this
example via contactors Q11 (M1) and Q12 (M2) at standstill. The
enabling and selection of the relevant parameter group is
activated via the digital inputs:
• Motor M1 = DI1 (FWD, control signal terminal 8) operation
with parameter group P7.
• Motor M2 = DI1 (FWD, control signal terminal 8) and DI6 (2PS,
control signal terminal 16) operation with parameter group P14
(second parameter set).
During maintenance and setting work the following applies for
reversing duty:
• Motor M1 = DI2 (REV, control signal terminal 9) operation with
parameter group P7.
• Motor M2 = DI2 (REV, control signal terminal 9) and DI6 (2PS,
control signal terminal 16) operation with parameter group P14
(second parameter set).

Digital input DI6 is assigned in the factory setting
(P3.12 = 6) with the function PI-OFF (PID controller,
deactivated). Setting P3.12 = 0 is used to switch off this
function of DI6. Setting P3.27 = 6 enables the second
parameter set (2PS) function to be assigned to digital
input DI6.
