Table 4B.I lists the analog servo module output specifications. This table
is provided as an aid to determining the compatibility of different analog
servo amplifiers and spindle drives. Table 12.A contains a list of
compatible analog servos. Input specifications are discussed in sections
covering the individual input devices. Refer to Table 4C.E for encoder
feedback input specifications.
