Anaheim Stepper DPF72452XCE Users Guide

							#L0101477 21        June 2008 Power  Requirements: The standard 115VAC version can accept power inputs ranging from
105VAC to 125VAC 50-60Hz. See Figure 14 for configurations with the
X250A version. Ambient Temperature: 0 to 50 degrees Celsius
Shipping Weight: 14.25 pounds
BLD72 DRIVER:
Control Inputs: TTL-MOS Compatible
Logic “0”: 0 to 0.8 Vdc
Logic “1”: 3.5 to 5 Vdc
All Inputs are pulled up; No connection= logic “1”.
Half-step/Full-step: Logic “1” - Half-step
(Terminal 8) Logic “0” - Full-step
Motor Power On/Off: Logic “1” - Motor energized
(Terminal 9) Logic “0” - Motor de-energized
Reset Fault: Logic “1” - Driver enabled and Fault detection enabled
(Terminal 4) Logic “0” - Resets a Fault condition (driver is disabled when this input is
low). This input must be held low for at least 100ms.
Output Current: 7.0 Amperes  continues  maximum
MANUAL PRESET INDEXER BOARD:
Control Inputs: TTL-MOS Compatible
Logic “0”: 0 to 0.8 Vdc
Logic “1”: 3.5 to 5 Vdc
All Input Terminals are pulled up
to +5Vdc through 1k ohm resistors.
Busy and Complete Outputs (pins 16 and 20) are open collector outputs that can sink 500mA and
stand-off 40Vdc maximum (no sourcing). Pull-up resistors may be jumpered to these outputs to pro-
duce TTL level signals (see section on jumpers).
Ground (pin 18) - 0Vdc
+5Vdc Output (TB2, pin 1) - Up to 250mA is available for the user to power up external circuitry. The total
current drawn from pin 1 and pin 2 must not exceed 250mA.
+12Vdc Unregulated Output (TB2, pin 2) - Up to 250mA is available for the user to power up external
circuitry. The total current drawn from pin 1 and pin 2 must not exceed 1.0A.

POWER WIRING
The DPF72452XCE can be configured to accept nominal power inputs of 100VAC, 115VAC, 130VAC,
215VAC, 230VAC, and 245VAC. See figure 12.

   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). 
						

							#L0101477 23        June 2008 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 Transistors
1. 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#
