Safety Installation Guide

WARNING

SAFETY OF PERSONNEL

The soft starter is not a safety device and does not provide electrical isolation or disconnection from the supply.

If isolation is required, the soft starter must be

•

installed with a main contactor.

Do not rely on the start and stop functions for

•

safety of personnel. Faults occurring in the mains supply, the motor connection, or the electronics of the soft starter can cause unintended motor starts or stops.

If faults occur in the electronics of the soft

•

starter, a stopped motor may start. A temporary fault in the supply mains or loss of motor connection can also cause a stopped motor to start.

To provide safety of personnel and equipment, control the isolation device through an external safety system.

NOTICE

All references to registers mean the registers within the module unless otherwise stated.

Conguring Soft Starter Parameters

7.3

Parameter management is always multiple write of the entire parameter block.

7.1 Compatibility

The Modbus TCP Module supports 2 modes of operation:

In standard mode, the module uses registers

•

dened in the Modbus Protocol Specication.

In legacy mode, the module uses the same

•

registers as the Modbus Module from Danfoss. Some registers dier from those specied in the Modbus Protocol Specication.

The values of bit 15 in register 40001 determine the operating mode.

Standard mode: Set bit 15 = 1. Bits 0–7 of register

•

40001 are used for command.

Legacy mode: Set bit 15 = 0. The remaining bits

•

of register 40001 are reserved.

Examples

10000000 00000001 = Start the motor (standard mode).

10000000 00000000 = Stop the motor (standard mode).

00000000 xxxxxxxx = Switch to legacy mode. The module ignores the remaining bits in register 40001 and checks the value in register 40002.

Ensuring Safe and Successful Control

7.2

conguring parameters in the soft starter, the PLC

When must be programmed with the correct values for all parameters. The card updates every parameter in the soft starter to match the values in the PLC.

CAUTION

UNPREDICATABLE BEHAVIOR

Do not change the default values of parameter group 20- ** Factory Parameters. Changing these values may cause unpredictable behavior in the soft starter.

7.4 Standard Mode

7.4.1 PLC Conguration

The PLC must be congured to map registers within the module to addresses within the PLC.

Data written to the Modbus TCP Module remains in its registers until the data is overwritten or the module is reinitialized. The Modbus TCP Module does not transfer successive duplicate commands to the soft starter.

If the soft starter is started via eldbus communi-

•

cations but stopped via the LCP or a remote input, an identical start command cannot be used to restart the soft starter.

If the soft starter may also be controlled via the

•

LCP or the remote inputs (and via eldbus communications), a control command should be immediately followed by a status query to conrm that the command has been actioned.

Table 7.3 Legacy Mode Registers

1) See the relevant soft starter manual for a complete parameter list.

The rst product parameter is always allocated to register 40009. The

last product parameter is allocated to register 40XXX, where XXX =

008 plus total number of available parameters in the product. The

Modbus TCP Module can read or write a maximum of 125 registers in

1 operation. These registers support multiple write (Modbus function

code 16). Attempting to write to a single register returns a fault code

01 (illegal function code).

2) Power scale functions as follows:

0 = Multiply power by 10 to get W.

1 = Multiply power by 100 to get W.

2 = Power (kW ).

3 = Multiply power by 10 to get kW.

Network Design Modbus TCP Module

8 Network Design

The device supports star, line, and ring topologies.

8.1 Star Topology

In a star network, all controllers and devices connect to a central network switch.

NOTICE

The device has an integrated switch to allow data to pass through in line topology. The device must be receiving control power from the soft starter for the switch to operate.

NOTICE

If the connection between 2 devices is interrupted, the controller cannot communicate with devices after the interruption point.

NOTICE

Each connection adds a delay to communication with the next device. The maximum number of devices in a line network is 32. Exceeding this number may reduce the reliability of the network.

8.3 Ring Topology

In a ring topology network, the controller connects to the

Illustration 8.1 Star Network Topology

8.2 Line Topology

In a line network, the controller connects directly to 1 port of the 1st module. The 2nd Ethernet port connects to another module, which in turn connects to another device until all devices are connected.

1st module via a network switch. The 2nd Ethernet port of the module connects to another device, which in turn connects to another device until all devices are connected. The nal device connects back to the switch.

The device supports beacon-based ring node congu-

ration.

Illustration 8.3 Ring Network Topology

Illustration 8.2 Line Network Topology

NOTICE

The network switch must support loss of line detection.
