5.8 H: Terminal FunctionsH parameters assign functions to the external terminals.u H1: Multi-Function Digital Inputsn H1-03 to H1-07: Functions for Terminals S3 to S7These parameters assign functions to the multi-function digital inputs. The various functions and settings are listed in Table5.20.Note: Setting F has been added and Setting 13 has been removed in bypass controller software versions VST800298 and later.No. Parameter Name SettingRange DefaultH1-03 Multi-Function Digital Input Terminal S3 Function Selection 3 to 60 24: External FaultH1-04 Multi-Function Digital Input Terminal S4 Function Selection 3 to 60 14: Fault ResetH1-05 Multi-Function Digital Input Terminal S5 Function Selection 3 to 60 3: Multi-Step Speed Reference 1H1-06 Multi-Function Digital Input Terminal S6 Function Selection 3 to 60 4: Multi-Step Speed Reference 2H1-07 Multi-Function Digital Input Terminal S7 Function Selection 3 to 60 6: Jog Reference SelectionTable 5.20 Multi-Function Digital Input Terminal SettingsSetting Function Page3 Multi-Step Speed Reference 1 1514 Multi-Step Speed Reference 26 Jog reference Selection 151C Analog Terminal Input Selection 151F <1> Not Used (Through Mode) 15110 Up Command 15111 Down CommandSetting Function Page13 <2> Reverse Jog 15214 Fault Reset 15319 PID Disable 15324 External Fault 15360 Motor Pre-Heat 1 153<1> Available in bypass controller software versions VST800298 and later.<2> Setting 13: Reverse Jog, is only available in bypass controller software versions VST800297 and earlier.Settings 3 and 4: Multi-Step Speed Reference 1 and 2Switches multi-step speed frequency references d1-01 to d1-04 by digital inputs. Refer to d1: Frequency Reference on page142 for details.Setting 6: Jog Reference SelectionThe Jog frequency set in parameter d1-17 becomes the frequency reference when the input terminal closes. Refer to d1:Frequency Reference on page 142 for details.Setting C: Analog Terminal Input Selection (Terminals A1 and A2)When closed, the terminals specified in H3-14 are enabled. When open, the drive disregards the input signal to the analogterminals.Setting F: Not Used (Through Mode)Note: Available in bypass controller software versions VST800298 and later.Select this setting when using the terminal in a pass-through mode. When set to F, an input does not trigger any function inthe drive. Setting F, however, still allows the input status to be read out by a PLC via a communication option or MEMOBUS/Modbus communications.Settings 10 and 11: Up/Down FunctionThe Up/Down function allows the frequency reference to be set by two push buttons when one digital input is programmedas the Up input (H1-oo= 10) to increase the frequency reference and the other digital input is programmed as the Down input(H1-oo= 11) to decrease the frequency reference.The Up/Down function takes priority over the frequency references from the HOA keypad, the analog inputs, and the pulseinput (b1-01 = 0, 1, 4). When using the Up/Down function, references provided by these sources will be disregarded.The inputs operate as shown in the table below:5.8 H: Terminal FunctionsYASKAWA ELECTRIC SIEP YAIZ1B 01E YASKAWA AC Drive – Z1000 Bypass Technical Manual 1515 Programming
