Functions
Hard Limit Switches: When a hard limit switch is encountered, the pulses will stop. Hard limits are
intended as an emergency stop for your system.
Soft Limit Switches: These switches cause the indexer to ramp down to the base speed and finish the
index, unless encountering a hard limit switch.
Profile Inputs: These inputs are used to select and begin the specified motion profile. Only 1 input should
be activated at a time.
Motion Profiles: The indexer will accept two different speed or motion profiles. Each profile has it own
programmable Accel/Decel, Base speed, Max speed and distance value. Theses values are stored in
EEProm for standalone use and must be programmed before the indexer is ran.
Acceleration/Deceleration: The acceleration and deceleration are by default the same value. This func-
tion controls the time that the motor will take to move from base speed to max speed. The higher the
value, the slower the motor will accelerate. The same principal applies for the deceleration which is con-
trolling the time it takes to go from maximum speed to base speed. The higher the value, the slower the
pulses will decelerate. The different accel/decel profiles are stored in EEprom for standalone use. (Range:
100 to 9,999,999)
Base Speed: The base speed is the speed at which motion starts and stops. It is entered directly as the
number of steps per second. This speed must always be less than the max speed. The different base
profiles are stored in EEprom for standalone use. (Range: 1 to 5000)
Max Speed: The max speed is the top speed the user wants the pulses to run at. This speed must always
be equal or greater than the base speed. It is entered directly as the number of steps/second. The differ-
ent max profiles are stored in EEprom for standalone use. (Range: 1 to 50,000)
Index Number: The index number is the number of steps that the motor will take when the motion profile
starts. It is entered directly as the number of steps to take. The different index profiles are stored in
EEporm for standalone use. (Range: 0 to 8,388,607)
Complete Time: The complete time is the duration that the complete output is held low after an index has
completed. This number is entered in the number of milliseconds that the output is to be held low.
Direction Input: If this input is open then the unit will be running in the clockwise direction. If this input is
active then the unit will be running in the counterclockwise direction. This pin can be overridden by the
programmable software direction. It will activate the direction output when the pin is changed. This means,
that if you start the profile from the software, the unit will look at the software direction. If you start the
indexer from the inputs, then the unit will look at the direction input.
Busy Output: This output will be pulled low when the indexer is operating. It is an open drain output so
when the indexer is not running the pin is open.
Complete Output: This output will be pulled low after the indexer is done indexing for the duration given in
the complete time parameter. It is an open drain output so when the output is not active the pin is open. It
is entered directly as the number of milliseconds the output will be active for. The different complete time
profiles are stored in EEprom for standalone use. (Range: 1 to 1000)
