AMCI 2762-17 Intelligent Position Control Module

The AMCI 2762-17 Intelligent Position Control Module is a two channel, non-servo positioning controller for Allen-Bradley 1771 I/O systems. Each channel has four DC outputs for motor speed and direction control and utilizes a brushless resolver based transducer for absolute multiturn position feedback. The 2762-17 is a true two channel controller that can drive both channels simultaneously.

Module configuration is accomplished from the processor or integral keyboard and display. Module configuration includes transducer setup , which sets the relationship of transducer position to load position, and positioning setup , which sets the loads' target position and the motor control parameters needed to reach the target position once a Move Profile is initiated.

Once configured, the 2762-17 waits for a move profile command. Once the command is given from the processor or keyboard, the module uses the transducer position to fire its motor control outputs at the appropriate positions. The 2762-17 turns the motor off at a programmed stop position and the load coasts to the target position.

If the load does not stop at the target position, the 2762-17 adjusts the stop position and runs the move profile again. Because inertia and friction in most systems is repeatable, the module can accurately position the load without servo feedback.

The 2762-17 also gives you the ability to jog the position from the processor, keyboard or external input.

The 2762-17 uses block transfer writes to program the module from the processor. It uses block transfer reads to transmit position and tachometer information or programming data back to the processor. The module uses single transfer writes to initiate move profiles or jog the load position from data in the output data table. It uses single transfer reads to transmit positioning status to the input data table. The 2762-17 can perform concurrent block and single transfers.
