4.6 Parameters: 5-** Digital In/Out4.6.1 5-0* Digital I/O ModeParameters for configuring the input and output usingNPN and PNP.5-00 Digital I/O ModeOption: Function:NOTICEPerform a power cycle toactivate the parameter once ithas been changed.Digital inputs and programmeddigital outputs are pre-programmable for operation eitherin PNP or NPN systems.[0] * PNP Action on positive directional pulses(↕). PNP systems are pulled downto GND.[1] NPN Action on negative directionalpulses (↕). NPN systems are pulledup to +24 V, internally in thefrequency converter.5-01 Terminal 27 ModeOption: Function:NOTICEThis parameter cannot beadjusted while the motor isrunning.[0] * Input Defines terminal 27 as a digitalinput.[1] Output Defines terminal 27 as a digitaloutput.5-02 Terminal 29 ModeOption: Function:[0] * Input Defines terminal 29 as a digitalinput.[1] Output Defines terminal 29 as a digitaloutput.The digital inputs are used for selecting various functionsin the frequency converter. Table 4.8 shows which functionscan be assigned to digital inputs.Functions in group 1 have higher priority than functions ingroup 2.Group 1 Reset, coast stop, reset, and coast stop, quick stop,DC brake, stop, and the [Off] key.Group 2 Start, latched start, reversing, start reversing, jog,and freeze output.Table 4.7 Function GroupsDigital input function Select TerminalNo operation [0] All, terminal 32, 33Reset [1] AllCoast inverse [2] All, terminal 27Coast and reset inverse [3] AllQuick stop inverse [4] AllDC brake inverse [5] AllStop inverse [6] AllStart [8] All, terminal 18Latched start [9] AllReversing [10] All, terminal 19Start reversing [11] AllEnable start forward [12] AllEnable start reverse [13] AllJog [14] All, terminal 29Preset reference on [15] AllPreset ref bit 0 [16] AllPreset ref bit 1 [17] AllPreset ref bit 2 [18] AllFreeze reference [19] AllFreeze output [20] AllSpeed up [21] AllSpeed down [22] AllSet-up select bit 0 [23] AllSet-up select bit 1 [24] AllCatch up [28] AllSlow down [29] AllCounter input [30] 29, 33Pulse input time based [32] 29, 33Ramp bit 0 [34] AllRamp bit 1 [35] AllExternal interlock [51] –DigiPot increase [55] AllDigiPot decrease [56] AllDigiPot clear [57] AllCounter A (up) [60] 29, 33Counter A (down) [61] 29, 33Reset Counter A [62] AllCounter B (up) [63] 29, 33Counter B (down) [64] 29, 33Reset counter B [65] AllPID error inv.
