5. Parameter Description
Eaton Electric General Inverters DF1 Series UMXXXXXXXXE February 2020 www.eaton.com
PID parameter group 1
Simulation of the feedback signal correction :
1.Please refer to 5.3.5 ~ 5.3.8 analog input selection and processing parts.
Example 1: The user does not answer the feedback signal
First set proportion parameter 02-14 (P. 194) = 0%, 02 to 15 (P. 195) = 100%;
02-12 set voltage parameters (P. 192) = 0, 11-13 (P. 193) = 7.
Example 2: Users choose AI3 terminals to 0 to 20 ma feedback signals
First set proportion parameter 02-27 (P. 196) = 0%, 02-28 (P. 197) = 100%;
To set the current parameter 02-25 (P. 198) = 0, 11-26 (P. 199) = 20.0
2.Users need to feedback signal correction
Example 3: User feedback range 0~10kg (3 to 5 analog input)
Adjust the feedback signal to 0 kg, write parameters 02-36 (P. 546) = 0%
Adjust the feedback signal to 10 kg, write parameters 02-37 (P. 547) = 100%

1. If the user wants to by adjusting the size of the analog input corresponding to a certain proportion relations, need to adjust
good analog input first, then set the corresponding proportion parameter, this time without setting voltage parameter, frequency
converter will calculate itself.If the user to skip regulating the relationship between analog input to set the proportion will be
expected to set a good first proportion parameters, voltage parameter Settings again.
2. Users such as case 3 that case, must be the actual feedback signal.
3 In the process of PID correction, the correction value must be the upper and lower limits of the selected signal.
4. If you use a AI3 terminals for the target source or source of feedback, please be sure to first set 02-20 value and collocation
of SW2 switch, choose AI3 terminal voltage/current signal is, to other actions.
5. If use 3 to 5 terminals for the target source or feedback, please be sure to first set SW1 switch 02-29 value and collocation,
choose AI2 terminal voltage/current signal is, to other actions.
• The instruction for the target pressure given by external analog terminal:
1. When the target value is set by terminalAI1(02-00=3 and 08-00=1X)
When 02-08 = 0, the given range is 0~5V corresponding to 0~100%;
When 02-08 = 1, the given range is 0~10V corresponding to 0~100%.
When the target value is set by terminal AI3(02-01=3 and 08-00=2X)
The given range is 4~20mA corresponding to 0~100%.
Example: Set 08-00 = 2X, 08-01 = 0.
It indicates that the PID target value is given by the current of terminalAI3(4~20mA).
If 8mA is given by the user, the corresponding given proportion is (8-4)/ (20-4) * 100.0= 25.0
