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.

R1A

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.

• Minimum switching capacity: 10mA for 24 Vdc.
• Maximum switching capacity on inductive load: 1.5 A for 250 V Vac (cos

30 Vdc (L/R 7 ms).

• Maximum response time: 20 ms.
