 Setting 12: It is used to display the status of the external multi-function output terminals,
including relay1, relay2, MO1 and MO2. The value it displays is hexadecimal number. It needs
to be converted to binary to get the result as following diagram.

 For example: when it displays o. C. After converting C(HEX) to binary (1100), it indicates that
the terminals MO1 and MO2 are ON.

Settings 0.1 to 160.0 Factory Setting: 1.0
 The coefficient K determines the multiplying factor for the user-defined unit.
The display value is calculated as follows:
U (User-defined unit) = Frequency Command * K (Pr.0-05)
H (actual output) = Actual output frequency * K (Pr.0-05)
Example:
A conveyor belt runs at 13.6m/s at motor speed 60Hz.
K = 13.6/60 = 0.21 (0.226667 rounded to 1 decimal), therefore Pr. 0-05=0.2
With Frequency command 35Hz, display shows U and 35*0.2=7.0m/s.
(To increase accuracy, use K=2.2 or K=22.7 and disregard decimal point.)
