Input/Output Standard The chassis includes: ESTOP, RS-232, GPIB Each
amplifier axis includes: CW, CCW, and Home limits; DIR,
CLK, Hall effects, amplifier thermistor; 1 channel of 16-bit
A/D per axis (±10 VDC)
Optional IO Board
(can be added to
each amplifier axis)
Eight opto-inputs with the IO board option; eight opto
outputs with the IO board option; sinking and sourcing
selection is available through the parameters; 5-24 VDC
can be used with any IO pins; single axis PSO (each axis
with optional IO; one additional 12-bit (±10 VDC) input and
one additional 16-bit (±5 VDC) output; brake relay: 0.5
amp solid-state relay available with option board;
secondary TTL RS-422 auxiliary encoder input; position
latch with 50 ns position capture latency
Encoder Inputs TTL RS-422 standard, and on optional IO auxiliary encoder input; optional
amplified sine encoder input on primary encoder channel; programmable
resolution up to 1024 times the analog encoder resolution; 10 MHz TTL RS-422
square wave primary or auxiliary encoder; 250 kHz amplified sine primary (with
optional onboard encoder multiplier board)
