For controllers with 5-8 axes, the ERR signal is duplicated on the I/O (E-H) D-Sub connector.
For additional information see Error Light (Red LED) in Chapter 9 Troubleshooting.
Electrical Specifications
Output Voltage 0 – 5 VDC
Current Output 20 mA Sink/Source
Analog Inputs
The DMC-40x0 has eight analog inputs configured for the range between -10V and 10V. The inputs are decoded by
a 12-bit A/D decoder giving a voltage resolution of approximately .005V. A 16-bit ADC is available as an option (Ex.
DMC-4020(-16bit)-C012-I000). The analog inputs are specified as AN[x] where x is a number 1 thru 8.
AQ settings
The analog inputs can be set to a range of ±10V, ±5V, 0-5V or 0-10V, this allows for increased resolution when the
full ±10V is not required. The inputs can also be set into a differential mode where analog inputs 2,4,6 and 8 can be
set to the negative differential inputs for analog inputs 1,3,5 and 7 respectively. See the AQ command in the
command reference for more information.
Electrical Specifications
Input Impedance (12 and 16 bit) –
Unipolar (0-5V, 0-10V) 42kΩ
Bipolar (±5V, ±10V) 31kΩ
Extended I/O
The DMC-40x0 controller offers 32 extended TTL I/O points which can be configured as inputs or outputs in 8 bit
increments. Configuration is accomplished with command CO – see Extended I/O of the DMC-40x0 Controller. The
I/O points are accessed through the 44 pin D-Sub connector labeled EXTENDED I/O. See the A9 – CMB-41012 (-
C012) section in the Appendix for a complete pin out of the Extended I/O.
