DESCRIPTION OF ATV58 TYPE FVC CONTROL TERMINALS
The ATV58 Type FVC control terminals are shown below. The location of the control terminal strip varies
from model to model. See page 18.
The control terminal strip contains four pull-apart terminal blocks, one for the relay outputs and three for
the low-level inputs and outputs. The S terminals are used to connect shield wires of multi-conductor
control cables for the low level inputs, outputs, and encoder. Maximum wire size for all control terminals
is 16 AWG (1.5 mm
2
). Tightening torque is 2.2 lb-in (0.25 N•m). The characteristics of the control
terminals are shown in the table below.
