Section 7. Driver (BLD72 SERIES DRIVER)

BILEVEL DRIVE

The basic function of a step motor driver is to provide the rated motor phase current to the motor windings in the shortest possible time. The bilevel driver uses a high voltage to get a rapid rate of current rise in the motor windings in the least amount of time. When reaching the preset trip current, the driver turns off the high voltage and sustains the current from the low voltage supply.

HALF-STEP/FULL-STEP

Users have a choice of full-step operation or half-step operation. 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 0.9 degrees per step. Full-step operation is suggested for applications that specifically require that mode, such as when retrofitting existing full-step systems.

To activate Full Step, jumper PIN 7 and PIN 8 on Driver Terminal Block.

MOTOR ON/OFF INPUT (Internally Connected)

The motor on/off input allows de-energizing a motor without disturbing the positioning logic. After re-energizing the motor, a routine can continue. This reduces motor heating and conserves power, especially in applications where motors are stopped for long periods and no holding torque is required. If holding torque is required (such as when lifting a load vertically), then this function should not be used. This output is internally connected to the Indexer. See Section 8 Command Descriptions for further information on Current Hold Command.

FAULT PROTECTION

There are 3 types of fault detection. When a fault is detected, the driver turns off the motor current and the red Fault LED indicates which type of fault occurred. (Located on the top of the driver pack.)

1	LED - Slow Blink	shorted wire in the motor or cable

2	LED - Fast Blink	open wire in the motor or cable

3	LED - ON Steady	ground fault (voltage shorted to 0V)

FAULT LED

If the driver goes into a fault condition, the fault may be reset by turning the power OFF for at least 15 seconds or by pulling the RESET FAULT input (terminal 4) to a logic “0" for at least 100ms.
