  • Page 3: Introduction

    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 ...
  • Page 4 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).
  • Page 5 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.

  • Page 7 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.
  • Page 8 E6581865  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.
