DIO2 Digital input/output DIO2 ( 11.02 DIO delayed status , bit 1). 9
Other [bit] Source selection (see Terms and abbreviations on page 148 ). -
76.11 Auto mode start
delay Defines the delay time before ESP control program activates
the process control mode selected with parameter
76.01 Auto
mode enable .
After the drive is started during the time set in this parameter,
the automatic process control remains inactive. The pump-
motor will follow speed reference selected in parameter
75.11
Pump speed ref source .
0
0...30000 s Automode start delay. 1 = 1s
76.19 Auto mode motor
ramp time Defines safe motor speed ramp setting used when automatic
process control mode is active.
In order to prevent undesired speed steps due to process
feedback signal errors or any other reason, it is
recommended to set this parameter value as high as it seems
reasonable it terms of expected speed change dynamics. 5.0
0.0...30000.0 s Auto mode motor ramp time. 1 = 1s
76.29 Invert PI error sign Selects the source to invert process PI controller error sign. Off
Off Invert process controller error sign is inactive.
Invert both Inverts both Process1 and Process 2.
Invert Process 1 Invert process 1 control error sign.
Invert Process 2 Invert process 2 control error sign.
76.31 Process 1 control
feedback src Defines the source for the process 1 feedback signal. Estimated
flowrate
NULL Zero 0
AI1 scaled 12.12 AI1 scaled value (see page 197 ). 1
AI2 scaled 12.22 AI2 scaled value (see page 199 ). 2
FBA1 ref 03.05 FB A reference 1 (see page 156 ). 3
FBA2 ref 03.06 FB A reference 2 (see page 156 ). 4
EFB1 ref 03.09 EFB reference 1 (see page 156 ). 5
EFB2 ref 03.10 EFB reference 2 (see page 156 ). 6
Estimated current Parameter 09.13 Motor current estimated (see page 183 ). 7
Motor current % Estimated motor current in % of nominal motor current. 8
Estimated flowrate Signal 85.91 Flowrate actual is used as the process feedback
source.
9
Estimated head Signal 85.92 Head actual is used as the process feedback
source.
