04.09 Multi-function Input Contact Selection Unit: 1
Settings 0–63 Default: 0
 Sets the contact status of external multi-function input terminals MI2–MI4 to be normally open (N.O.) or
normally closed (N.C.) according to the start-up / stop mode (Pr.04.19 and Pr.04.04).
 When the start-up/stop mode is single-wired, MI1 setting is invalid; when the start-up/stop mode is two-wired,
MI2 setting is invalid; when the start-up/stop mode is three-wired, MI2 and MI3 settings are invalid. See the
table below for details.

 Setting method: When setting this parameter, covert Bit3–Bit0 that represent the status of MI4–MI1 from
binary to decimal.
For example: setting MI3 and MI4 to be 1 = N.C.; seting MI1 and MI2 to be 0 = N.O.
The setting value for Pr.04.09 should be 12.
 This parameter delays the signals on digital input terminals. A value of 1=2 ms, 2=4 ms, and so on. The delay
time helps with noisy signals that could cause the digital terminals to malfunction. This parameter could
effectively improve the interference, but the response time will be delayed.
04.26 Display the Status of Multi-function Input Terminal
Settings Read Only Default: Read Only
 Displays 63 in Pr.04.26 when all the MI terminals are not active.
1. When MI1 (corresponds to bit0) is triggered, and the weight is 1, Pr.04-26=62 (63-1).
2. When MI2 (corresponds to bit1) is triggered, and the weight is 2, Pr.04-26=61 (63-2).
