Input / Output Descriptions
INPUTS
Voltages:
+5 VDC, –5 VDC, Ground
CS:
Chip Select. Active LO. Logic transition
enables data output.
SCLK:
Serial interface clock. Data is clocked out
on “rst” negative edge of SCLK, after a
LO transition on CS. Twelve pulses to
clock data out.
OUTPUTS
Standard
Absolute Position
DATA:
Serial Interface Data.
(DRBB & DRBG versions)

> scanning frequency (384 KHz)
NM:
Encoder North Marker emulation output.
Pulse triggered as code passes through
zero. 90° pulse width (180° and 360°
using NMC)
Optional
VEL:
Indicates angular velocity of input signals
(150 rps / VDC)
Load drive capability: ±250 A at
V
out = ±2.5 VDC
NMC:
North Marker width Controller
(90°, 180°, or 360°)
CLKOUT:
Internal VCO clock output; indicates
angular velocity of input signals
(4 KHz / rps)
DIR:
Indicates direction of rotation of input
LOGIC HI = Increasing angular rotation
= CW shaft rotation
LOGIC LO = Decreasing angular rotation
= CCW shaft rotation
(DRBB & DRBG versions)
NOTE:
OUTPUT LOAD CAPABILITY:
