5 Transformer Drawings 3.750 MAX 4.500 3.100 2.500 1.450 MAX 1.500 .800 MAX 2.350 3.570 3.000 Figure 6: Transformer Dimensions Note: The AA2793 transformer is the same physical size as the AA2791, but it has two sets of secondary windings (to power two drivers) and a dual primary winding for 115/230V operation. Figure 8: AA2793 Transformer Specs Figure 7: AA2791 Transformer Specs 6 Figure 9: Wiring for different line voltages for the AA2793 transformer. 7 Dimensions Drawings Figure 10: BLD72 Dimensions Note: The BLD72 and BLD72-1 are the same except for the base plate. The BLD72 is a replacement driver for use in Driver Packs. The BLD72-1 is a modular driver which has a larger base plate.

Notes: Other motors not listed above may be compatible with this driver. Anaheim Automation carries a full-line of standard and high torque step motors. Contact the factory regarding compatibility. See back cover for speed/toque curves. 9 Specifications Control Inputs (All) : (Terminals 5, 6, 8, 9) TTL-compatible Logic “0” - 0 to 0.8 V Logic “1” - 3.5 to 5.0 V Fault Reset: (Terminal 4) Pulled up to +5VDC through a 10k Ohm resistor Logic “1” (open) - Driver enabled and Fault detection enabled Logic “0” - Resets a Fault condition (driver is disabled when this input is low). This input must be held low for at least 100ms. Clock Inputs : (Terminals 5 and 6) Pulse required; 15 microseconds minimum. The clock input is pulled up/down internally to +5VDC / 0VDC through a 10k Ohm resistor, based upon JP2 selection. Direction Control: (Terminal 5) Pulled up to +5Vdc through a 10k Ohm resistor Logic “1” (open) - CW Logic “0” - CCW Excitation Mode Select: (Terminal 8) Pulled up to +5Vdc through a 10k Ohm resistor Logic “1” (open) - Half-step Logic “0” - Full-step Power ON/OFF: (Terminal 9) Logic “1” (open) - motor current on Logic “0” - motor current off Output Current Rating: (Terminals 1, 2, 3, 11, 12, and 13) 10 Amps/phase maximum operating current, 7.0 Amps/phase maximum standstill current, over the operating voltage and temperature range. Motor phase ratings of 1.0 Amp minimum are required to meet the minimum kick level. Power Requirement: Anaheim Automation recommended transformer. Operating Temperature : 0 to 60 degrees C It is recommended that the aluminum driver baseplate be mounted on a larger aluminum plate, or similar heat-conducting structure, whenever possible. This will prevent the driver baseplate from overheating and degrading driver reliability. Fan cooling is also recommended whenever possible. FUSING: A 5 Amp Fast Blow fuse in series with the primary winding of the transformer is required. 10 Troubleshooting 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? (Once a second) 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 accurate, then the output transistors should be checked (see below). Is the LED blinking quickly? (Three times a second) This indicates that there is an open or intermittent 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”. NOTE: If the ground fault detection is disabled, DO NOT connect the driver’s 0V to earth ground! Checking Output Transistors 1. Remove the side plate 2. Set the multimeter to Diode Test 3. Place the RED meter lead on (between) the Sense Resistors ...
