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 Ta b l e 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 Ta bl e 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 Ta b le 3 1

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 Ta ble 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 Tab l e 3 1

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.
