1 A digital input (1…8 only) must be configured for “Enable”.
2 For digital inputs 9…12, this option is not available (displays as “Reserved”).
Option Description
Enable (1)(2) Removing the enable input causes the motor to coast-to-stop without generating a fault.
Stop/CF
(2)
Stops the drive if running or jogging or clears a fault if the drive is already stopped.
Start
(2)
Issues a Start command, removal does not Stop the drive (3-wire control).
Fwd/Reverse
(2)
Selects the operating direction of the drive. 0 = Forward, 1 = Reverse
Run (2) Issues a Start command, removal causes the drive to Stop (2-wire control).
Run Forward (2) Issues a Run command in the Forward direction.
Run Reverse
(2)
Issues a Run command in the Reverse direction.
Run Level
(2)
Level sensitive Run command (no off-to-on transition required).
RunFwd Level
(2)
Run Level command in the Forward direction.
RunRev Level (2) Run Level command in the Reverse direction.
Jog (2) Starts the drive and runs at the speed in Par 266 [Jog Speed], removal causes the drive to Stop.
Jog Forward
(2)
Issues a Jog command in the Forward direction.
Jog Reverse
(2)
Issues a Jog command in the Reverse direction.
Aux Fault Asserting causes an Auxiliary Input fault (F2).
Clear Faults Issues a Clear Faults command.
Auto/Manual Selects between Automatic and Manual speed reference values.
Speed Sel 1 - 3 Selects one of eight speed references. Bit enumerations: 000 = Par 44 [Speed Ref A], 001 = Par 48 [Speed Ref B], 010 = Par 155 [Preset Speed 2], 011 = Par 156 [Preset Speed 3], 100 = Par 157 [Preset Speed
4], 101 = Par 158 [Preset Speed 5], 110 = Par 159 [Preset Speed 6], 111 = Par 160 [Preset Speed 7]
PI Enable Enables/disables the PI block of the PID regulator (Par 769 [Enable PI]).
PI Hold Enables/disables a hold on the PI output.
PI Reset Asserting causes a reset of the PI output.
PI Invert Asserting causes an inversion of the PI output.
Local Enables exclusive drive control via the I/O Terminal Block only.
Acc2 & Dec2 Switches between the Accel/Decel 1 and Accel/Decel 2 ramp rates.
Accel 2 Switches between the Accel 1 and Accel 2 ramp rates.
Decel 2 Switches between the Decel 1 and Decel 2 ramp rates.
MOP Inc Asserting causes the MOP reference to increment at the rate set in Par 22 [MOP Accel Time].
MOP Dec Asserting causes the MOP reference to decrement at the rate set in Par 30 [MOP Decel Time].
Fast Stop Causes the drive to Stop at the rate set in Par 38 [Fast Stop Time].
Contactor Indicates the status of the main contactor/DB contactor. Must be assigned and asserted in order to run drive when Par 1391 [ContactorControl] = “Contactor” or “Contactor+DB”.
MOP Reset Asserting resets the MOP reference to zero.
TorqueReduce Turns on /off Torque Reduction using the reduced current limit set in Par 13 [Torq Red CurLim].
Force MinFld When asserted, the field current is set to the value specified in Par 498 [Force Min Field]. Important: See Attention statement on page 183 for this option. Not used for permanent magnet motor applications.
Freeze Ramp Holds the speed ramp at the present value (Par 373 [Freeze Ramp]).
UsrDefinedA0-7 Writes the value of the digital input to Pars 520 [UsrDefBitWrdA0] - 527 [UsrDefBitWrdA7].
Droop Enable Enables/disables the Droop function (699 [Enable Droop]).
PD Enable Enables/disables the PD block of the PID regulator (Par 770 [Enable PD]).
PI Cent vs0 - 1 In combination, the digital inputs set to “PI Central vs0” and “PI Central vs1”, through binary selection, determine which of the four possible output values is used as the initial level of the integral component
(corresponding to the initial diameter) of the PI block. See Par 780 [PI Central vs0] for binary selection values.
Diam Calc When asserted initiates the diameter calculation (Par 794 [Diameter Calc]).
Diam Reset Sets the diameter starting value to the value in Par 1168 [Diam Preset Sel].
DiamCalc Dis Enables/disables the diameter calculation (Par 1161 [Diameter Calc Dis]).
Torq Wind En Enables/disables the Center wind function (Par 1209 [Torque Winder En]).
Speed Match When asserted, issues the coil 'launch phase' command for automatic switching (Par 1195 [Speed Match]).
Diam I/D En Enables/disables the ability of the diameter calculation to increase for an unwider or decrease for a winder (Par 1205 [Diam Inc Dec En]).
Wind/Unwind Sets the value of Par 1187 [Winder Type] to “0” Winder or “1” Unwinder .
Diam Preset0 - 1 Selects the value of Par 1164 [Diam Preset 0], 1165 [Diam Preset 1], Par 1166 [Diam Preset 2], or Par 1167 [Diam Preset 3] See Par 1168 [Diam Preset Sel].
Taper Enable Enables/disables the Taper function (Par 1176 [Taper Enable]).
Spd DemandEn Enables/disables the speed reference calculation (winder operation), (Par 1215 [Speed Demand En]).
Winder Side Selection of the winding/unwinding side (0 = up, 1 = down).
PI-PD Enable Selection between PI and PD (winder operation), (Par 1201 [Winder Side]).
Jog TW En Enables/disables the Torque Winder jog function (Par 1256 [Jog TW Enable]).
Invert Flt Must be used when the digital input is wired to the status of an inverting fault device (fuse, circuit breaker, etc.). Removing the input causes an “Inverting Fault” (F37).
