2.2 General Warnings
WARNING
ELECTRICAL SHOCK HAZARD
VLT®Soft Starter MCD 500 contains dangerous voltages
when connected to mains voltage. Only a qualied
electrician should carry out the electrical installation.
Improper installation of the motor or the soft starter can
cause death, serious injury, or equipment failure. Follow
the guidelines in this manual and local electrical safety
codes.
Models MCD5-0360C ~ MCD5-1600C:
Treat the busbar and heat sink as live parts whenever
the unit has mains voltage connected (including when
the soft starter is tripped or waiting for a command).
WARNING
PROPER GROUNDING
Disconnect the soft starter from mains voltage before
carrying out repair work.
It is the responsibility of the person installing the soft
starter to provide proper grounding and branch circuit
protection according to local electrical safety codes.
Do not connect power factor correction capacitors to the
output of the VLT®Soft Starter MCD 500. If static power
factor correction is employed, it must be connected to
the supply side of the soft starter.
WARNING
IMMEDIATE START
In auto-on mode, the motor can be controlled remotely
(via remote inputs) while the soft starter is connected to
mains.
MCD5-0021B ~ MCD5-0961B:
Transportation, mechanical shock, or rough handling
may cause the bypass contactor to latch into the On
state.
To prevent the motor from starting immediately on rst
commissioning or operation after transportation:
•Always ensure that the control supply is applied
before the power.
•Applying control supply before power ensures
that the contactor state is initialized.
WARNING
UNINTENDED START
When the soft starter is connected to AC mains, DC
supply, or load sharing, the motor can start at any time.
Unintended start during programming, service, or repair
work can result in death, serious injury, or property
damage. The motor can start with an external switch, a
eldbus command, an input reference signal from the
LCP or LOP, via remote operation using MCT 10 Set-up
Software, or after a cleared fault condition.
To prevent unintended motor start:
•Press [O]/[Reset] on the LCP before
programming parameters.

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.

7 Modbus Registers
NOTICE
All references to registers mean the registers within the
module unless otherwise stated.
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.
7.2 Ensuring Safe and Successful Control
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.
7.3 Conguring Soft Starter Parameters
Parameter management is always multiple write of the
entire parameter block.
When conguring parameters in the soft starter, the PLC
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.

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.

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.
177HA628.10
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.
177HA629.10
Illustration 8.2 Line Network Topology
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
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.
177HA630.10
Illustration 8.3 Ring Network Topology
NOTICE
The network switch must support loss of line detection.
