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 inp uts and outputs. The S terminal is

used for the shield connection. Maximum wire size for all c ontrol terminals is

14 AWG (1.5 mm2). Tightening torque is 3.5 lb-in (0.4 N•m). The

characteristics of the control termina l s 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.
