Anaheim Stepper PCL451 Users Guide

Specifications
Power Requirements:
The PCL451 can be powered three different ways. The most common is with 9-12VAC (TB2, pins 5 & 6).
The second way to power the PCL451 is using voltages of +5VDC (TB2, pin 1) or +9VDC to +15VDC
(TB2, pin 2). If the AC inputs are used then the +5VDC and +12VDC unregulated can be used as outputs.
If the +9VDC to +15VDC is used then only the +5VDC can be used as an output. If +5VDC is used to
power the board, then no output voltages are available. The +5VDC output can...

Busy and Complete Outputs:
These are open collector outputs that can sink 500mA and stand-off 40VDC maximum (no sourcing). Pull-
up resistors may be added to these outputs to produce TTL level signals.
For typical applications, relays are used on the outputs Busy and Complete.
K1 will energize immediately after completion of an index cycle and remain energized for approximately
an amount of time set by the “Complete Pulse Width” pot. K2 will be energized throughout an index cycle.

Count Input Boards
All of the count input boards or modules set the number of steps the motor will move when an index is
initiated, but each module allows for a different variation in interfacing.
AA1748 - Click Pot Module
A ‘click pot’ module consists of 10 position (0 - 9) digital pots mounted on a printed circuit board. One pot
is used per each decade (digit). These units are available in 2, 4, or 6 decades. The user dials in the step
count on the pots. Any time the motor is indexed, it will move...

Note: All inputs are active low (0-0.8Vdc). All unused inputs may be ignored since they are pulled up.
Example: For a move distance of 1234 steps the following inputs should be pulled low.
1’s Decade: Bit 4 (TB1, pin 4)
10’s Decade: Bit 1 and 2 (TB2, pin 2 and 3)
100’s Decade: Bit 2 (TB1, pin 7)
1000’s Decade: Bit 1 (TB2, pin 6)
All other inputs must be open or high (3.5-5VDC). AA2210 BCD Counter Module
The AA2210 BCD counter interface module enables the user to select any move length from 0 to...

The selection of the switch banks is done by switching select lines 1 and 2 on connector P3. The select
lines are “low true” meaning that if a select line is pulled low (to 0VDC), it is recognized as being “on” or
“true”. When a select line is not pulled low it is internally “pulled up” to +5VDC and is “off” or “false”. The
bank select lines must be set at least 1 millisecond before the index command is given. The select lines
must remain in the set state until the index is complete. Once the move is...
