Setting Up Parameters
Velocity
The Velocity parameter specifies the velocity used for the index. The velocity parameter is unsigned and must be greater than
zero.
Acceleration
The Acceleration parameter specifies the acceleration value to be used during the index. The acceleration is specified in units
of ms/(k(user unit)/min) or user units/sec
2
, depending on the time base parameter from the User Units View.
Deceleration
The Deceleration parameter specifies the deceleration value to be used during the index. The deceleration is specified in units
of ms/(k(user unit)/min) or user units/sec
2
, depending on the time base parameter from the User Units View.
Dwell Time
Time in ms between indexes. The dwell starts at the end of the commanded motion of the index, and the output line End of
Index is turned on at the end of the dwell time. Default is 0 ms. Upper limit is 65,535 seconds.
Index Count Group
This parameter specifies how many times in a row this index is to run before proceeding on to the next index.
Repeat Forever
If repeat forever is chosen, the index will repeat continuously until a stop command is received.
Repeat For Count
If repeat for count is chosen, the user must specify how many times the index is to repeat. The maximum index count is
65,535.
Repeat while Input Function Active
If repeat while input function active is chosen, the index will repeat continuously when the Repeat Current Index input is
active.
Registration Tab
The registration index parameters are set on this tab. The signal for the registration mark can come from one of four sources:
Registration Sensor 1, Registration Sensor 2, Torque Level 1, or Torque Level 2.
The Offset can either be Calculated by PowerTools Pro or Specified by the user in user units. If Calculated Offset is selected,
the motor will stop at the specified deceleration ramp. If Specified Offset is selected, the motor will come to a stop the
specified offset distance away from the registration mark. If the Specified offset is less than the Calculated offset, the motor
will stop at the programmed deceleration ramp and then back up to the specified distance from the registration mark. The
Specified offset is a signed parameter; if the index direction is negative, the specified offset parameter should also be negative.
Calculations Tab
This displays various index calculations, such as index distance, index time, acceleration, deceleration and at velocity results.
Start Position
When an “Absolute Index” is selected, the “Start Position” of the index can be set to provide index calculations from a non-
zero position. The “Start Position” is defaulted to zero. The “Start Position” parameter is not available using an “Incremental
Index”.
Chain Tab
Multiple indexes can be chained together so that they run sequentially. As each index is configured, this tab allows for no
chaining or end of the chain (stop), continue to the next index (start next index), or wait for a Run Next Index Input signal
and continue to next index (wait for run...). Which index is to be run next is specified in the Index Chain text box. The default
chain setting is Stop.
