more information about these commands, see the Command Summary. The value of the outputs can be checked with the operand _OP and the function @OUT[x] (see Chapter 7, Mathematical Functions and Expressions).

Controllers with 5 or more axes have an additional eight general use TTL outputs.

NOTE: For systems using the ICM-1900 interconnect module, the ICM-1900 has an option to provide optoisolation on the outputs. In this case, the user provides a an isolated power supply (+5volts to +24volts and ground). For more information, consult Galil.

The output compare signal is TTL and is available on the ICM-1900 as CMP. Output compare is controlled by the position of any of the main encoders on the controller. The output can be programmed to produce an active low pulse (1usec) based on an incremental encoder value or to activate once when an axis position has been passed. For further information, see the command OC in the Command Reference.

The error signal output is available on the interconnect module as ERROR. This is a TTL signal which is low when the controller has an error.

Note: When the error signal is low, the LED on the controller will be on, indicating one of the following error conditions:

1.At least one axis has a position error greater than the error limit. The error limit is set by using the command ER.

2.The reset line on the controller is held low or is being affected by noise.

3.There is a failure on the controller and the processor is resetting itself.

4.There is a failure with the output IC which drives the error signal.
