(2) Use remote pressure gauge of 0-10kg; as required, use external terminal to control the
operation and stop and set target value via potentiometer. As shown in Figure F-6.

[Note]
1) Target value of D5M series inverter can be selected through two methods,
one referring setting via panel and the other one referring to 0-10V analog ;
2) Feedback signal is 4-20mA and the others are invalid;
3) Target value in the case is set via potentiometer (0-10V);
4) P156, P157 and P158 shall be set based on concrete conditions (refer to parameter
description for details);
5) PID special control board is designed as common remote pressure gauge and input
internal resistance is converted into standard signal as per 0-
400Ω; in case that the
resistance of remote pressure gauge used by the user exceeds prescribed limit,
remote pressure gauge shall be replaced or the previous resistor shall be connected
in parallel for calibration;
6) Output resistances of remote pressure gauges are various for they are supplied by
different manufacturers; after conversion, current signal varies in size, so the user
can specifically set target value based on actual situations to make it consistent with
actual condition;
7) When target value is set via potentiometer, P002 still must be set to 0; otherwise,
PID shall be ineffective.
