Description
Related
At Speed
Relay changes state when drive has reached commanded speed.
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).
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.
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.
Micro Pos
Micropostion input. When closed, the command frequency is set to a percentage speed
reference as defined in [MicroPos Scale%], parameter 611.
MOP Dec
Decrements speed reference as long as input is closed.
MOP Inc
Increments speed reference as long as input is closed.
MtrTrqCurRef
Torque producing current reference.
Param Cntl
Parameter controlled analog output allows PLC to control analog outputs through data
links. Set in [AnlgX Out Setpt], parameters 377-378.
Param Cntl
Parameter controlled digital output allows PLC to control digital outputs through data
links. Set in [Dig Out Setpt], parameter 379.
PI Reference
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.
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).
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.
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.
Torque Setpt 1
Selects “Torque Stpt1” for [Torque Ref A Sel] when set, otherwise uses value selected in
[Torque Ref A Sel].
Vel Override
When active, multiplies value of [Step X Velocity] by % value in [Vel Override].
