LINE FUSING
External line fuses must be installed on all SimpleServos. Connect the external line fuse in series with the
AC line voltage input. Table 3 lists the recommended line fuse sizes. Use fast acting fuses rated for 250
VAC or higher, and approximately 200% of the maximum phase current.

SIMPLESERVO CONNECTIONS
Prefabricated cable assemblies may be purchased from AC Technology Corp to facilitate wiring the
control, motor and host computer. Contact your AC Technology Corp sales representative for assistance.
ENCODER FEEDBACK
An encoder needs to have power supplied to it. SimpleServo has a +5 VDC supply voltage that is used to
power the encoder. If front-end controller power supply needs to be used to power the encoder one has
to be disconnected from SimpleServo power supply by removing connections to PWR +5V pins.
WARNING!
Use only +5 VDC encoders. Do not connect any other type of encoder to the
SimpleServo reference voltage terminals. When using a front-end controller, it is
critical that the +5 VDC supply on the front-end controller NOT be connected to the +5
VDC supply on the SimpleServo, as this will result in damage to the SimpleServo.
Note:
AC Technology Corp recommends an encoder resolution of 2000 PPR or higher for
optimum performance.
WIRE SIZE
If current draw is less than 8 amps: 16 AWG (1.0 mm) or 14 AWG (1.6 mm)
If current draw is greater than 8 amps, but less than 12 amps: 14 AWG (1.6 mm) or 12 AWG (2.6 mm)
If current draw is greater than 12 amps: 12 AWG (2.6 mm).
