PARAMETER DESCRIPTION 235
5.9.14 PID current feedback disconnection detection
When PID feedback is a current signal (4~20mA), it is used to detect feedback signal disconnection.

PID current feedback disconnection detection

Example: When PID feedback is 4-20mA current signal. If the 4-5 terminal input is the source of feedback, the
inverter should slow down and stop after the feedback signal is disconnected for 10.0s during operation, and AEr
alarm should be reported, the following parameters should be set: 02-01(p.501)= 4,02-20(p.17)=
0,08-00(p.170)=X2, 08-45(P.253)=10.0s,08-46(P.254) =1.
