5.6 H: Terminal Functions 5.6 H: Terminal Functions H parameters are used to assign functions to the external terminals. u H1: Multi-Function Digital Inputs These parameters assign functions to the multi-function digital inputs. The settings 0 to 67 determine function for each terminal and are explained below. n H1-01 to H1-05: Functions for Terminals S1 to S5 Note: If not using an input terminal or if using the through-mode, set that terminal to “F”. Number appearing in parenthesis is the default value after performing a 3-Wire initialization. Table 5.15 Digital Multi-Function Input Settings Setting 0:
3-Wire Sequence When one of the digital inputs is programmed for 3-Wire control, that input becomes a forward/reverse directional input, S1 becomes the Run command input, and S2 becomes the Stop command input. The drive will start the motor when the Run input S1 is closed for longer than 50 ms. The drive will stop the operation when the Stop input S2 is released for a brief moment. Whenever the input programmed for 3-Wire sequence is open, the drive will be set for forward direction. If the input is closed, the drive is set for reverse direction. Note: When 3-Wire sequence is selected the Run and Stop command must be input at S1 and S2.
