VFD-M-D Series
5-18 Revision Jan. 2007, MDE2, SW V1.05
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.

0 - 05 User Defined Coefficient K Unit: 0. 1
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.)
