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 53. 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 15
and
Table 16 on page 55
.
Two 4...20 mA analog output signals for indication signals such as output motor
current and frequency. See Tab le 15
and Table 16 on page 55.
Sixteen passive dry contact inputs (internal 24V DC power supply) start/stop
and reset controls. For detailed information, see Ta b le 1 5
and Table 16 on
page 55. 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 Tabl e 15
and Table 16 on
page 55. 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 1 5
and Table 16 on page 55.
Modbus RTU interface is supplied as standard (other communication interfaces
including Modbus TCP, Modbus Plus, EtherNet/IP, and Profibus are provided as
options). For detailed information, see Figure 31 on page 54
.
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 21
or Figure 22).
The wiring terminates either to the DTB1 or DTB2 terminal block strips on
either side of the LV Control cabinet (Figure 23
). See Figure 30 or Figure 31 for
general information. Refer to Electrical Drawings for actual connection points.
