Siemens CU240B-2 Operating Instructions

6.19 Free technology controllers
Additional PID technology controller
The inverter has three additional technology controllers.
The three "free technology controllers" have fewer setting options compared with the PID
technology controller described above.

Figure 6-34 Simplified function chart of the additional PID technology controllers, n = 0 … 2
You can find the complete function chart 7030 in the List Manual.
The additional technology controllers allow several process variables to be simultaneously
controlled using one inverter. An example is a HVAC system with heating and cooling valves
to process the air:
● The main controller controls the speed of the fan drive.
● The additional technology controllers control the cooling and heating via the two analog
outputs available.
Parameters using the free technology controller 0 as example
Parameter Remark
p11000 BI: Free tec_ctrl 0 enable (Factory setting: 0)
1 signal: Technology controller is enabled.
p11053 CI: Free tec_ctrl 0 setpoint signal source (Factory setting: 0)
p11057, p11058 Free tec_ctrl 0 setpoint ramp-up time and ramp-down time (Factory setting: 1 s)
p11063 Free tec_ctrl 0 error signal inversion (Factory setting: 0 s)
0: No inversion
1: Inversion
p11063 must be set = 1 if the actual value decreases with increasing motor
speed.
p11064 CI: Free tec_ctrl 0 actual value signal source (Factory setting: 0)
