GEMINI MAXIMUM FREQUENCY INPUT AND OUTPUT

The table below contains the maximum input command frequency (50 pin connector, pins 8-11) and output pulse frequency (50 pin connector, pins 14-17) for the Gemini Family:

	Maximum Input Frequency (pins 8-11)		Maximum Output Frequency (pins 14-17)
	Encoder	Step Pulse	If Encoder Input Used	If Step Pulse Input Used
GV	2 MHz pre-quad encoder	2 MHz	2.5 MHz post-quad encoder	2.5 MHz post-quad encoder
GV6	N/A	N/A	2.5 MHz post-quad encoder	2.5 MHz post-quad encoder
GV6K	N/A	N/A	2.5 MHz post-quad encoder	2.5 MHz post-quad encoder
GT	2 MHz pre-quad encoder	2 MHz	625 KHz step pulse	625 KHz step pulse
GT6	N/A	N/A	625 KHz step pulse	625 KHz step pulse
GT6K	N/A	N/A	625 KHz step pulse	625 KHz step pulse

Note: If ORES=ERES for GV, GV6 and GV6K, maximum output frequency is 8 MHz post-quad (2 MHz pre-quad).

The GV, GV6 and GV6K maximum feedback frequency (26 pin connector, pins 5-8) is 2 MHz pre-quadrature and 8 MHz post-quadrature.

(Pre-Quadrature = Per Channel)
