GENERAL DESCRIPTION

The ANAHEIM AUTOMATION DPD72PG1 Step Motor Driver Pack is designed to operate 6-lead, 4-phase step motors rated at 1 - 7

amps/phase. This Driver Pack contains a BLD72 Step Motor Driver, an AA2876 Ramping Pulse Generator, a 300 Watt transformer,

and a cooling fan. Outstanding motor performance is provided by means of a Bilevel Drive technique.

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. A rapid rise in winding current is achieved by applying a high voltage directly

to a motor. This rapid rise of current is also referred to as the "kick" or operating current. When a desired current level is reached, a

low voltage is applied to maintain a suitable holding current level. When a motor winding is turned off, a rapid decrease in winding

current is achieved by routing the energy in the collapsing field back to the power supply through a high voltage path. The high voltage

supply furnishes the energy necessary to maintain motor output torque at high step rates thus providing high mechanical power output.

The low voltage supply provides much of the current needed at low step rates and all of the holding current.

Bilevel drivers do not use high frequency switching techniques as chopper drivers do. Consequently, they do not create the EMI, RFI,

and motor heating problems that are associated with chopper drivers.

EXCITATION MODE SELECT

Users have a choice of dual-phase, full-step operation or half-step operation. Dual-phase, full-step operation occurs by energizing two

phases at a time, rotating a typical motor 1.8 degrees per step. Half-step operation occurs by alternately energizing one, and then two,

phases at a time, rotating the motor O.9 degrees per step. Full-step operation is only suggested for applications that specifically require

that mode, such as when retrofitting existing full-step systems.

STEP AND DIRECTION CONTROL

The Clock output of the AA2876 Pulse Generator is internally wired to the Clock input of the Driver board. Terminal 5 on the driver

side is the Direction Input. A logic "1" on this input selects Clockwise motor direction. A logic "0" on this input selects

Counterclockwise direction.
