29.04 Internal set 1 Defines process setpoint 1 when parameter 29.02 Setpoint 1
src is set to Int set 1.
0.00 … 32768.00% Internal process setpoint 1. 100 = 1%
29.05 Internal set 2 Defines process setpoint 2 when parameter 29.03 Setpoint 2
src is set to Int set 2.
0.00 … 32768.00% Internal process setpoint 2. 100 = 1%
29.06 Reference step 1 Sets a percentage that is added to the process setpoint
when one auxiliary (direct-on-line) motor is running.
Example: The drive operates three parallel pumps that pump
water into a pipe. The pressure in the pipe is controlled. The
constant pressure reference is set by parameter 29.04
Internal set 1. During low water consumption, only the
speed-regulated pump is run. When water consumption
increases, constant-speed (direct-on-line) pumps are
started: first one pump, and if the demand grows further, also
the other pump. As water flow increases, the pressure loss
between the beginning (point of measurement) and the end
of the pipe increases. By setting suitable reference steps,
the process setpoint is increased along with the increasing
pumping capacity. The reference steps compensate the
growing pressure loss and prevent the pressure fall at the
end of the pipe.
0.00 … 100.00% Reference step 1. 100 = 1%
29.07 Reference step 2 Sets a percentage that is added to the process setpoint

parameter 29.06 Reference step 1.
0.00 … 100.00% Reference step 3. 100 = 1%
29.09 Reference step 4 Sets a percentage that is added to the process setpoint
when four auxiliary (direct-on-line) motors are running. See
parameter 29.06 Reference step 1.
0.00 … 100.00% Reference step 4. 100 = 1%
29.10 Reference step 5 Sets a percentage that is added to the process setpoint
