If select line #4 is low, that quad board is ignored and the count input device connected to the P2 expansion connector is read. This allows multiple quad boards to be used together. The daisychained count input device does not have to be a quad board; it could be a thumbwheel switch or click pot module.
2122 FIGURE 10 AA2210 BCD COUNTER MODULE
The AA2210 BCD counter interface module enables the user to select any
move length from 0 to 999,999 steps using a standard PLC (programmable
logic controller). Selecting the proper inputs creates a count value in steps,
resulting in a move distance. The module is connected to the indexer via a
supplied 5-lead cable.
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.
1s Decade: Bit 4 (TB1, pin 4)
10s Decade: Bit 1 and 2 (TB2, pin 2 and 3)
100s Decade: Bit 2 (TB1, pin 7)
1000s Decade: Bit 1 (TB2, pin 6)
All Other inputs must be open or high (3.5-5Vdc).FIGURE 11: Dimensions SPECIFICATIONS
Power Requirements: The standard 115VAC version can accept power
inputs ranging from 105VAC to 125VAC 50-60Hz.

FIGURE 12: POWER HOOKUP DIAGRAM FOR DPD72451X250AX250A VERSION The DPD72451X250A can be configured to accept nominal power inputs of 100VAC, 115VAC, 130VAC, 215VAC, 230VAC, and 245VAC. See figure 14.
25 TROUBLESHOOTING DRIVER FAULTS If a Fault occurs, reset the Fault by applying a logic “0 to the Reset Fault Input (terminal 4) for at least 100ms (or by cycling power OFF for at least 15 seconds). After resetting, try to run the motor again. If the driver faults again then check the conditions listed below. Is the LED blinking Slowly? This indicates that the motor has a phase shorted or there is a short in the motor cable or wiring. Check the motor and the wiring for shorts. If the driver continues to sense “shorts” after the motor and wiring are determined to be good, then the output transistors should be checked (see below). Is the LED blinking Quickly? This indicates that there is an open connection in one of the motor wires. Check the motor and the wiring for opens. Another condition that may cause this type of fault is when a large motor is ramped down too quickly so that it loses it’s positioning. Is the LED on Steadily? This indicates that there is a ground fault - a voltage shorted to 0V. This detection is useful in detecting a short-to-case in a motor when the motor’s case AND the driver’s 0V are both connected to earth ground. Excessive noise on the 0V line may also cause the driver to sense this type of fault. This type of fault sensing may be disabled by placing jumper JP3 in position “1-2 (see figure 3A). NOTE: IF THE GROUND FAULT DETECTION IS DISABLED, DO NOT CONNECT THE DRIVER’S 0V TO EARTH GROUND! Checking Output Transistors1.Remove the side plate on the driver side of the unit. 2.Set the multimeter to Diode Test. 3.Place the RED meter lead on Pin 7 (0Vdc) of the driver terminal block. 4.Touch the BLACK meter lead to each phase (terminals 1, 2, 12, and 13). 5.Readings should be between 0.450V and 0.550V. 6.If any readings are significantly less than 0.450V, then the unit has been damaged. To send the unit in for repair, contact the factory for an RMA#. 910 E.
