Option Description Related
At Speed Relay changes state when drive has reached commanded speed. 380
Fast Stop When open, the drive will stop with a 0.1 second decel time. (If Torque Proving is being
used, float will be ignored at end of ramp and the mechanical brake will be set). 361
Excl Link Links digital input to a digital output if the output is set to “Input 1-6 Link.” This does
not need to be selected in the Vector option. 361
Find Home Starts the commissioning procedure when a start command is issued to automatically
position the motor to a home position established by a limit switch.
Hold Step Inhibits profile from transitioning to next step when active.
Home Limit This input is used for the “home” position.
Input 1-6 Link When Digital Output 1 is set to one of these (i.e. Input 3 Link) in conjunction with
Digital Input 3 set to “Excl Link,” the Digital Input 3 state (on/off) is echoed in the
Digital Output 1. 380
Micro Pos Micropostion input. When closed, the command frequency is set to a percentage speed
reference as defined in [MicroPos Scale%], parameter 611. 361
MOP Dec Decrements speed reference as long as input is closed. 361
MOP Inc Increments speed reference as long as input is closed. 361
MtrTrqCurRef Torque producing current reference. 342
Param Cntl Parameter controlled analog output allows PLC to control analog outputs through data
links. Set in [AnlgX Out Setpt], parameters 377-378. 342
Param Cntl Parameter controlled digital output allows PLC to control digital outputs through data
links. Set in [Dig Out Setpt], parameter 379. 380
PI Reference Reference for PI block (see Process PID on page 134 ). 342
Pos Redefine Redefines the “home” position for the drive by latching encoder position.
Pos Sel 1-5 Binary value of these inputs is used to select the starting step number for the profile.
Precharge En Forces drive into precharge state. Typically controlled by auxiliary contact on the
disconnect at the DC input to the drive. 361
Profile Input Must be chosen if [Step X Type] is set to “Dig Input” and the digital input value that is
entered in [Step X Value] is the value of this digital input selector.
Pulse In Ref Reference of the pulse input (Z channel of encoder - can be used while A & B channels
are encoder inputs). 342
RunFwd Level
RunRev Level
Run Level Provides a run level input. They do not require a transition for enable or fault, but a
transition is still required for a stop.
Run w/Comm Allows the comms start bit to operate like a run with the run input on the terminal
block. Ownership rules apply.
Scale Block 1-4 Output of scale blocks, parameters 354-355. 342
SpdFb NoFilt Provides an unfiltered value to an analog output. The filtered version “Speed Fdbk”
includes a 125 ms filter.
Torque Est Calculated percentage of rated motor torque. 342
Torque Setpt 1 Selects “Torque Stpt1” for [Torque Ref A Sel] when set, otherwise uses value selected in
[Torque Ref A Sel]. 361
Vel Override When active, multiplies value of [Step X Velocity] by % value in [Vel Override].
