1. Introduction
My function-S adds programming capability to inverter’s input/output signals without external
relays or a PLC (programmable logic controller) in some cases.
The function makes it possible to reduce the space and cost required for the system.
2. Parameters used
My function-S uses the parameters  to .
 For details of each parameter, refer to the relevant section.
3. Summary of My function-S
My function-S has the combined terminal function that combines the functions of the inverter’s
input and output terminals and the relay sequence function that combines logic operation
functions.
Combined terminal function
The combined terminal function is activated to assign two or more functions to one terminal.
The function can reduce the numbers of terminals and cables for your required operations.
And it is possible to process some circuit without external circuit.
For example, you can assign the standby signal (default setting: always active) and the forward
run command signal (default setting: Terminal F) to one terminal (example: Terminal F).
Terminal F can perform the two functions.
See Example 1 in Chapter 5 for details.

The combined terminal function can be used for output signals.
For example, you can assign the low speed detection signal (function No: 4) and small current
detection (function No: 26) to one terminal (Terminal OUT). When both signals are detected,
Terminal OUT outputs signal.
See Example 4 in Chapter 5 for details.

Relay sequence function
In case that an inverter is controled by a PLC (programmable logic controller), the PLC receives,
processes, and sends the signals as processing result to the inverter.
(See Fig 3-1.)
The relay sequence function enables the inverter to perform itself in 28 steps without a PLC.
Because the function uses internal data and signals directly, the processing speed is faster than
control with the PLC.
Furthermore, the function enables the inverter to use its multi-function input and output signals
at the same time, and thus to perform various operations in a reduced number of steps.

«Example» Start forward run with a push switch (non self hold switch).
Stop automatically if the output current is 120% or more of the rated current when
the output frequency is 5Hz or less.
For the sake of simplicity, stop signal input terminals are omitted here.

4. Setting parameters
This chapter explains how to set parameters related to the My function-S using the composition
of the My function-S and the rules.
Input terminals
Input signal terminals that can be used with the My function-S are as follows;
●Input terminals (8 terminals: F, R, RES, S1, S2, S3, VIA, VIB)
VF-S15 has 8 input terminals.
The input terminals are used for following 2 ways.
1) Input terminals to which assign multiple functionss
2) Simple ON-OFF signal input terminals like a PLC
In this manual, such input terminals are referred to as X1, X2 to X8 to distinguish them
from case 1).
●Virtual input terminals (4 terminals)
Virtual input terminals cannot be turned on and off electronically unlike actual input terminals.
Virtual input terminals can be turned on and off using communication function or My
function-S. You can assign the multiple functions as same as actual input terminals.

●Internal terminals (8 terminals)
Internal terminals cannot be turned on and off electronically unlike actual input terminals.
Internal terminals can be turned on and off using communication function or My function-S.
You can not assign the multiple functions as same as the virtual input terminals.
They correspond to the internal relay used in PLC. They are used for preserving and reading
the status.
Computing function
The My function-S can perform logical operations on input/output signals and compares and
computes some data, such as frequency, current, and torque data that the inverter detects.
A table of computing functions is shown in Appendix 2.
Available data that the inverter detects are listed in Appendix 5.
●Logical comparison
●Commutation

Output terminals
Output signal terminals used with the My function-S are following.
●Output terminals (3 terminals: RY, OUT, FL)
VF-S15 has 3 output terminals.
You can assign the multiple functions to the output terminals.
A table of output terminal functions is shown in Appendix 4. Only the positive logic settings
are used for My function-S.
Note) Negative logic settings of output terminal functions cannot be used for the My
function-S.
Computation results can be output by assigning the My function-S output 1 to 16 to the
output terminals .
Setting parameters
The My function-S consists of 7 units of the same composition. Each unit consists of 4 steps,
and therefore there are 28 steps in total. See Fig.4-1 for the composition of each unit.
Each step consists of one command.
Each unit begins with a data read (LD) command as step 1 and ends with a data transfer (ST)
command as step 4. You set the commands and objects to step 2 and 3 in accordance with the
requested functions.
Unit 1 Unit 2 Unit 7
Step 1 LD a900 Step 1 LD a906 Step 1 LD a953
Step 2 a901 a902→ Step 2 a907 a908 →→ Step 2 a954 a955
Step 3 a903 a904 Step 3 a909 a910 Step 3 a956 a957
Step 4 ST a905 Step 4 ST a911 Step 4 ST a958
