Values
Data Type Related
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 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 195
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]).
