Anaheim BLD72-1 Specifications, Control Inputs All Terminals 5, 6, 8, Fault Reset Terminal

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 oper- ating 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.
