34 DESCRIPTION AND FUNCTION MANUAL PRESET INDEXER BOARD The Manual Preset Indexer board utilizes the PI45 Preset Indexer integrated circuit (I.C.). Functions available are Home, Hard and Soft Limit inputs, two Homing modes, Jog/Run, Fast Jog and switch selectable Base Speed, Maximum Speed, Acceleration/Deceleration. This board includes the necessary buffering and other circuitry for the PI45 chip that makes indexing easy. The board can be operated manually or with a Programmable Logic Controller (PLC)...

A logic “1 or open selects the Internal Index Count Number. A logic “0 selects the count of an external counter module. 14HOME SELECTThis input selects the type of Home operation to perform: When active low, H0 Homing Mode is selected. It is a standard deceleration and stop on switch operation. In essence, type H0 is a combination of the HOME...

If any type of fault is detected, the driverFAULT PROTECTION will turn off current to the motor, and the Fault LED will indicate which type of fault occurred.There are three types of fault detection. When a fault is detected, the driver BILEVEL DRIVEoccurred. See the Troubleshooting section for more information. The basic function of a step motor driver is to control the motor winding currents. Motor performance is determined by how...

It can be seen from the table above that this speed can only be obtained with the F switch setting of 0 through 4. Any of these switch settings could provide speeds in excess of 4500 steps/second. The rule of thumb is to always chose the highest F switch setting...

STOPS SLOWS DOWN SCREWHOME LIMIT SOFT LIMIT NUT STEP MOTOR1516 HOMING MODES There are two Homing Modes that may be initiated, H0 and H1. H0 HOMING MODE: This mode causes the motor to run at Max Speed in the direction selected. The motor runs until the nut encounters the SOFT limit switch, at which time the motor decelerates to the Base Speed. The nut continues to run at Base Speed until it hits the Home limit switch. This may be illustrated by using a step motor driving a leadscrew as shown below....

1718 FIGURE 6 To use an external Count Module, the INT/EXT input (pin 13) must be pulled low to a logic “0. The on-board switches will be ignored. External Count Modules plug into either connector labeled “EXTERNAL COUNT MODULE CONNECTOR”(P1 or P2). When only using one module for both FORWARD and REVERSE indexes, jumper JP2 must be in the “1-2 position. When using external Count Modules, it is possible to use one module for FORWARD indexing and another module for REVERSE indexing. The connector on...
