TABLE OF CONTENTS INTRODUCTION PAGE INTRODUCTION . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 The DPD72451 Driver Pack contains a Bilevel Step Motor Driver (BLD72), a Manual Preset Indexer board, a Transformer, and a cooling fan. Figure 1 shows the general configuration and layout of the DPD72451 Driver Pack. The Thumbwheel Switch is used to set the index (number of steps or move distance) and the Manual switches and/or PLC are used to initiate indexing, homing or jogging.

DESCRIPTION AND FUNCTION MANUAL PRESET INDEXER TERMINAL (P1) DESCRIPTION MANUAL PRESET INDEXER BOARD PIN 1 FUNCTION -HARD LIMIT The Manual Preset Indexer board utilizes the PI45 Preset Indexer integrated circuit (I.C.). Functions available are Home, Hard and Soft Limit inputs, two Homing modes, Jog/Run, Fast Jog and switch selectable Base Speed, Maximum Speed, Acceleration/Deceleration. 2 +HARD LIMIT Same as -HARD LIMIT except in CW direction.
PAGE 4
12 +INDEX Same as -INDEX, but commands a CW step motion. 13 #INT/EXT This input determines which set of switches will be used for counting. A logic “1" or open selects the Internal Index Count Number. A logic “0" selects the count of an external counter module. 14 HOME SELECT This input selects the type of "Home" operation to perform: When active low, H0 Homing Mode is selected. It is a standard deceleration and stop on switch operation.

against shorted and open motor wires. If any type of fault is detected, the driver will turn off current to the motor, and the Fault LED will indicate which type of fault occurred. BILEVEL DRIVE The basic function of a step motor driver is to control the motor winding currents. Motor performance is determined by how fast the driver can increase and decrease the winding currents.

MOTOR/DRIVER CONNECTIONS BLD72 DRIVER TERMINAL DESCRIPTION Figure 3 shows the proper connection of the step motor. The CLOCK (pin 6) and DIRECTION (pin 5) inputs on the driver terminal block are internally connected to the CLOCK and DIRECTION outputs of the indexer (nothing should be connected to these inputs).

Figure 5 shows a typical velocity profile of a step motor.

It can be seen from the table above that this speed can only be obtained with the F switch setting of 0 through 4. Any of these switch settings could provide speeds in excess of 4500 steps/second.
PAGE 9
HOMING MODES There are two Homing Modes that may be initiated, H0 and H1. H0 HOMING MODE: This mode causes the motor to run at Max Speed in the direction selected. The motor runs until the nut encounters the SOFT limit switch, at which time the motor decelerates to the Base Speed. The nut continues to run at Base Speed until it hits the Home limit switch. This may be illustrated by using a step motor driving a leadscrew as shown below.

To use an external Count Module, the INT/EXT input (pin 13) must be pulled low to a logic “0". The on-board switches will be ignored. External Count Modules plug into either connector labeled “EXTERNAL COUNT MODULE CONNECTOR”(P1 or P2). When only using one module for both FORWARD and REVERSE indexes, jumper JP2 must be in the “1-2" position. COUNT INPUT BOARDS When using external Count Modules, it is possible to use one module for FORWARD indexing and another module for REVERSE indexing.

AA1754 - QUAD BOARD COUNTER The quad board module is a 4-bank version of the clickpot module with each bank having 6 decades. The user can "dial in" four different move lengths and then select any one of them as desired. The module is connected to the indexer via a supplied 5-lead cable. 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".
PAGE 12
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. SPECIFICATIONS FIGURE 11: Dimensions Power Requirements: The standard 115VAC version can accept power inputs ranging from 105VAC to 125VAC 50-60Hz.
PAGE 13
Reset Fault: (Terminal 4) Output Current: Logic "1" - 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. X250A VERSION The DPD72451X250A can be configured to accept nominal power inputs of 100VAC, 115VAC, 130VAC, 215VAC, 230VAC, and 245VAC. See figure 14. 7.0 Amperes continues maximum MANUAL PRESET INDEXER BOARD: Control Inputs: TTL-MOS Compatible Logic "0": 0 to 0.

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.
