DESCRIPTION OF CONTROL TERMINALS
All ATV58 TRX Type E, Type F, Type H, and Type N models have the same
control terminals, shown in the figure to the left. The locations of the control
terminals varies from model to model as shown on pages 18 and 19.
The control terminal strip contains two pull-apart terminal blocks, one for the
relay outputs and one for the low-level inputs and outputs. The S terminal is
used for the shield connection. Maximum wire size for all control terminals is
14 AWG (1.5 mm
2 ). Tightening torque is 3.5 lb-in (0.4 N•m). The
characteristics of the control terminals are shown in the table below.
Terminal Function Characteristics
R1A
R1B
R1C
R1A to R1C is a N.O. contact. When the
drive controller is powered with no fault,
the contact is closed.
R1B to R1C is a N.C. contact. When the
drive controller is powered with no fault,
the contact is open.
