Signal Wiring

Introduction

This section summarizes the control signal wiring from the remote DCS/PLC or
discrete control to the drive. General connections are detailed in

Power Cabling

and Control Signal Wiring Details on page 85

. Refer to the Electrical Drawings

for connection information specific to the drive being installed.

Analog and Digital I/O Overview

Four 4...20 mA analog input signals. One may be used for DCS with rotating
speed setting and three for backup. For detailed information, see

Table 31

and

Table 32 on page 89

.

Two 4...20 mA analog output signals for indication signals such as output motor
current and frequency. see

Table 31

and

Table 32 on page 89

.

Sixteen passive dry contact inputs (internal 24V DC power supply) start/stop
and reset controls. For detailed information, see

Table 31

and

Table 32 on

page 89

. These inputs are scalable depending on user requirements.

Twenty dry contact outputs: including nine active dry contact outputs with a
capacity of not more than 20W for indication (backup), and 11 passive dry
contact outputs powered by the drive with a capacity of 220V AC/5A for DCS
status/fault indication. For detailed information, see

Table 31

and

Table 32 on

page 89

. These outputs are scalable depending on user requirements.

The drive is provided with dry contact outputs (1 N.O. with a capacity of
220V AC/5 A, valid when closed) which trigger the user-provided medium
voltage circuit breaker for interlock with the user-provided medium voltage
switch cabinet. For detailed information, see

Table 31

and

Table 32 on page 89

.

Ethernet interface is supplied as standard (other communication interfaces
including Modbus and Profibus are provided as options). For detailed
information, see

Figure 53 on page 88

.

Wiring Routing and Connection

The control signal wiring enters the drive through the same opening as the
control power wiring in the LV Control Cabinet (

Figure 31

or

Figure 32

).

The wiring terminates either to the X1 or X2 terminal block strips on either side
of the LV Control cabinet (

Figure 33

). See

Figure 50

or

Figure 51

for general

information. Refer to Electrical Drawings for actual connection points.
