E6581865 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 ...
E6581865 <Standard> <My function-S> Coast stop Coast stop Output frequency Output frequency [Hz] [Hz] terminal F terminal F terminal S1 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).
E6581865 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.

E6581865 ● 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.

E6581865 Examples of the setting of the combined terminal function <Example 1: Performing 2 functions by 1 terminal> Standby signal is connected with Terminal F (Forward run command). (F+ST) Standby signal is connected with Terminal R (Reverse run command). (R+ST) See Fig 5-1 for wiring diagram and Fig.5-2 for block diagram.

Assign the standby (ST) to Terminal S1. Assign the forward run command (F) to virtual input terminal 1. If the Terminal S1 is turned on, the virtual terminal is turned on automatically.
E6581865 <Example 3: Performing 3 functions by 1 terminal> Performing standby, forward run command and preset-speed command 1 by the Terminal S1. (ST+F+SS1) See Fig 5-5 for wiring diagram and Fig.5-6 for block diagram. Assign the standby (ST) to Terminal S1. Assign the forward run command (F) to virtual input terminal 1.
E6581865 <Example 4: Output signal by logical product of 2 functions> Output the signal on the condition of detecting both a low-speed signal and a small current signal from Terminal OUT. See Fig 5-7 for block diagram. Compute by logical product (AND) of a low-speed signal and a small current signal. Transfer the result to the My function-S output1, and output signal from Terminal OUT.
E6581865 Examples of the setting of the relay sequence function This section gives an explanation of the relay sequence function using ladder diagrams. One unit consists of maximum 4 steps. If your sequence consists of 5 steps or more, you need to change the composition to 4 steps or less.
