Option Description
Spd Zero Thr “0” indicates that the drive is operating below the value set in Par 107 [Speed Zero Level] , “1”
indicates that the drive is operating above Par 107 [Speed Zero Level].
Spd Thresh “0” indicates that the drive is operating above the value set in Par 101 [Speed Thresh Pos], “1”
indicates that the drive is operating below Par 101 [Speed Thresh Pos].
At Speed “0” indicates that the actual speed is within the range specified in Par 104 [At Speed Error], “1”
indicates that the actual speed is outside the range specified in Par 104 [At Speed Error].
CurrentLimit “0” indicates that the drive is not limiting output current, “1” indicates that the drive is limiting the
output current.
Ready “1” indicates that the drive is powered, Enabled and no Start Inhibits exist. The state of the assigned
digital output matches the state of bit 2 “Ready” of Par 381 [Drive Status 1].
Ramp Pos “1” indicates that the actual speed of the drive is going positive. Follows the state of Par 346 [Torque
Positive]. Not asserted until after the amount of time in Par 20 [Ramp Delay] has elapsed.
Ramp Neg “1” indicates that the actual speed of the drive is going negative. Follows the state of Par 347 [Torque
Negative]. Not asserted until after the amount of time in Par 20 [Ramp Delay] has elapsed.
Spd Limited “1” indicates that the speed is being limited to the value of Par 3 [Max Speed Fwd], “0” indicates that
the speed is not being limited.
Fault “0” indicates that a drive fault has occurred. Refer to Par 57 [Fault Code].
Power Loss “0” indicates that the drive has detected a loss of the internal power supply.
UserDefinedA Indicates the status of Par 519 [UsrDefBitWrdA] (digital output 1 uses bit 0, digital output 2 uses bit 1,
etc.). Par 1392 [Relay Out 1 Sel] uses bit 14 (only). Par 629 [Relay Out 2 Sel] uses bit 15 (only).
UserDefinedB Indicates the status of Par 536 [UsrDefBitWrdB] (digital output 1 uses bit 0, digital output 2 uses bit 1,
etc.). Par 1392 [Relay Out 1 Sel] uses bit 14 (only). Par 629 [Relay Out 2 Sel] uses bit 15 (only).
Stop Control Energized (“1”) at run and de-energized (“0”) based on the value of Par 627 [Spd 0 Trip Delay].
Field Loss “0” indicates the loss of the field voltage/current while the drive is running.
Spd Fbk Loss “0” indicates the loss of Speed Feedback/Encoder due to an excessive calculated error, as
determined by the drive firmware.
Encoder Err “0” indicates a loss of the DC tachometer or encoder. Matches the state of Par 651 [Encoder State].
Diam Calc Energized (“1”) when Par 800 [Diameter Calc St] = 1 and de-energized (“0”) when [Diameter Calc St]
= 0.
Input1 Cmp “1” indicates that the value of analog input 1 is inside the comparison window,“0” indicates that the
value of analog input 1 is outside the comparison window (Par 1045 [Anlg In1 Cmp Eq]).
Diam Reached Energized (“1”) when the value of Par 1158 [Diam Threshold] has been exceeded.
Speed Match Energized (“1”) when the value of Par 1203 [Spd Match Compl] = “1” (launching ramp completed).
Accelerating “1” indicates that the drive is actively accelerating. The state of the assigned digital output matches
the state of bit 4 “Accelerating” of Par 381 [Drive Status 1] and the state of Par 1188 [Accel Status].
Decelerating When set to “1” the drive is actively decelerating. The state of the assigned digital output matches the
state of bit 5 “Decelerating” of Par 381 [Drive Status 1] and the state of Par 1189 [Decel Status].
Brake Cmd Energized (“1”) at run (opens the brake) after the value in Par 1263 [Opening Delay] has been
exceeded. De-energized (“0”) at stop (closes the brake) after the drive speed goes below the value of
Par 1262 [Closing Speed].
ContactorDB “1” issues the close command to the main contactor and dynamic brake contactor.
Contactor “1” issues the close command to the main contactor.
Alarm “0” indicates that a drive alarm has occurred. Refer to Par 1380 [Drive Alarm 1].
Running “1” indicates that the drive is active in Run mode. The state of the assigned digital output matches the
state of bit 2 “Running” of Par 381 [Drive Status 1].
Jogging “1” indicates that the drive is active in Jog mode. The state of the assigned digital output matches the
state of bit 3 “Jogging” of Par 381 [Drive Status 1].
Active “1” indicates that the drive is active in Run or Jog mode. The state of the assigned digital output
matches the state of bit 1 “Active” of Par 381 [Drive Status 1].
