Marker Output
Supported resolver packages
1326AB-MOD-VD1:x single resolver
package.
x = rotor to input shaft ration
x = 1, 2, 2.5, or 5
1326AB-MOD-VD:256/255 dual
resolver package.
256/255 is the master to vernier gear
ratio.

package.
a = mounting configuration
b = connector style
c = connector location
d = gear ratios
R2 = Harlowe resolver element
11BRCX-300-C or equivalent. e
replaces c if mating connector is
supplied.
Use cable 845AB-CA-i-xx
