Installation

Enable Input Connection

The ENBL (enable) input is located on the AUX connector. The 6250 is shipped with ENBL

wired to GND (see drawing) to allow motor motion.

See the illustration above for an example connection using a normally-closed switch.

Opening the switch sets the ±10V analog command output to zero volts and activates the

shutdown outputs; this is done independent of microprocessor and DSP control. The encoder's

position is retained when the ENBL input is activated. If the ENBL input is not grounded when

motion is commanded, the error message WARNING: ENABLE INPUT INACTIVE will be

displayed.

If error bit #9 of the ERROR command is enabled, the error program (ERRORP) will be

executed. You can check the status of the ENBL input with the TINO, INO, TER and ER

commands.

Programmable Inputs & Outputs Connections

The PROGRAMMABLE INPUTS connector provides 24 programmable inputs and the

PROGRAMMABLE OUTPUTS connector provides 24 programmable outputs. Two additional (and

functionally identical) programmable outputs, OUT-A and OUT-B, are available on the AUX

connector. Two additional trigger (position latch) inputs are also available on the AUX

connector, but due to their functional differences they are discussed later in the Triggers

section. All these inputs and outputs are optically isolated and TTL compatible.

All 26 programmable outputs are pulled up using the OUT-P pin on the AUX connector (see

illustration above). The 6250 is factory wired for +5VDC logic. If +5VDC is not to be used,

disconnect OUT-P from the +5V terminal and connect OUT-P to an external supply of up to

24V. Note: Even if you use an external 24V supply the switching thresholds remain TTL

compatible ( ≤ 0.4V = Low,

≥ 2.4 V = High).

Change inputs from

sourcing to sinking.

All 24 programmable inputs are pulled up to +5V by connecting the IN-P terminal to the +5V

terminal on the AUX connector. If you wish to have the inputs sink current instead of source

current, you can connect IN-P to GND. For compatibility with equipment operating at

24VDC, the inputs may be pulled up to 24VDC by using an external power supply. The

trigger inputs (TRG-A & TRG-B) are internally tied to 5V, but can have up to 24V connected to

them.

These I/O are typically used with normally-open or normally-closed switches; however, they

can also be used with I/O module racks, PLCs, and thumbwheels (including the Compumotor

TM8).

If you are using PLCs or thumbwheels, refer to the connection instructions and application

considerations provided in the Programmable Inputs and Outputs section of Chapter 5.

Also provided in the Programmable Inputs and Outputs section are instructions for defining

and controlling programmable inputs and outputs via programs written with the 6000 Series

programming language.
