Anaheim Automation manufactures Driver Packs with a built-in Manual Preset Indexer, matched power supply, and cooling fan. These Driver Packs employ a bilevel drive technique, so that they do not create the EMI, RFI, and motor heating problems. The DPD72451 is a single-axis model, while the DPF72452 is a two-axis model. Both units can drive 4-phase stepper motors rated at 1 to 7 Amps per phase. The Manual Preset Indexer can be operated manually or with a Programmable Logic Controller (PLC) to index a set of pulses determined by the internal count switches or an external count module, such as a Thumb Wheel Switch Counter (AA1760 Series). Functions include Home, Hard and Sift Limit inputs, two Homing modes, Jog/Run, Fast Jog, and switch-selectable Base Speed, Max Speed and Acceleration/Deceleration. Thumbwheel and other counter modules are purchased separately.

Anaheim Automation's DPFHP451 is a single-axis Driver Pack with a built-in Manual Preset Indexer, matched power supply, and cooling fan. The DPFHP451 employs a high-performance bilevel driver technique, so EMI, RFI, and motor heating problems are eliminated. The DPFHP451 can drive 4-phase stepper motors rated at 1.4 to 12.5 Amps per phase. The Manual Preset Indexer can be operated manually or with a Programmable Logic Controller (PLC) to index a set of pulses determined by the internal count switches or an external count module, such as a Thumb Wheel Switch Counter (AA1760 Series). Functions include Home, Hard and Sift Limit inputs, two Homing modes, Jog/Run, Fast Jog, and switch-selectable Base Speed, Max Speed and Acceleration/Deceleration. The MBC10SI1 is a microstep driver with a simple indexer feature, rated at 1 to 10 Amps per phase.
