1
A digital input (1-8 only) must be configured for “Enable”.
2
This option is not available (“Reserved”) for digital inputs 9 - 12.
Option
Description
Enable
(1)(2)
Asserting the 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.
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 “CoDB”.
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].
Field Reg En
Enables/disables the field regulator (Par 497 [Field Reg Enable])
Force MinFld
When asserted, the field current is set to the value specified in Par 498 [Force Min Field].
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. Refer to 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

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 .
