Selecting a Drive The SLC Servo Module supports Allen-Bradley 1386, 1388, 1389, 1391,
1392, 1394, and 1398 servo drive systems. References that help you
select a suitable drive system appear in the table below.
The SLC Servo Module provides a ±10V analog output to one drive
amplifier for a velocity command. This analog voltage is 11 bits plus
an additional sign bit (12 bits total) and interfaces to drive amplifiers
with a 2K through 20K ohm range. Servo drive signal analog out
specifications appear in the table below.
