Electrical Specifications

Servo Control

ACMD Amplifier Command:	+/-10 Volts analog signal. Resolution 16-bit DAC
	or .0003 Volts. 3 mA maximum
A+,A-,B+,B-,IDX+,IDX- Encoder and Auxiliary	TTL compatible, but can accept up to +/-12 Volts.
	Quadrature phase on CHA,CHB. Can accept
	single-ended (A+,B+ only) or differential (A+,A-
	,B+,B-). Maximum A,B edge rate: 12 MHz.
	Minimum IDX pulse width: 80 nsec.

Stepper Control

Pulse	TTL (0-5 Volts) level at 50% duty cycle.
	3,000,000 pulses/sec maximum frequency
Direction	TTL (0-5 Volts)

Input/Output

Uncommitted Inputs, Limits, Home, Abort	2.2K ohm in series with optoisolator. Active high or low
Inputs:	requires at least 2mA to activate. Can accept up to 28
	Volts without additional series resistor. Above 28 Volts
	requires additional resistor.
AN[1] thru AN[8] Analog Inputs:	Standard configuration is +/-10 Volt. 12-Bit Analog-to-
	Digital convertor. 16-bit optional.
OUT[1] thru OUT[8] Outputs:	TTL.
Extended I/O (17 – 80)	TTL. Configurable as input or output in banks of 8 with
	CO command.

Note: The part number for the 100-pin connector is #2-178238-9 from AMP.
