SAFETY
This option is specifically designed to be used with the
ACS250/ACS255 variable speed drive product and is intended for
professional incorporation into complete equipment or systems. If
installed incorrectly it may present a safety hazard. The
ACS250/ACS255 uses high voltages and currents, carries a high level
of stored electrical energy, and is used to control mechanical plant that
may cause injury. Close attention is required to system design and
electrical installation to avoid hazards in either normal operation or in
the event of equipment malfunction.
System design, installation, commissioning and maintenance must be
carried out only by personnel who have the necessary training and
experience. They must read carefully this safety information and the
instructions in this Guide and follow all information regarding transport,
storage, installation and use of the Option module, including the
specified environmental limitations.
Please read the IMPORTANT SAFETY INFORMATION below, and all
Warning and Caution boxes elsewhere.
CAUTION
•Store the Option in its box until
required. It should be stored in a
clean and dry environment.
Temperature range –40oC to
+60oC.
•Install the Option by inserting the
row of 11 pins into the terminal
connector of the ACS250/ACS255
ensuring that the terminals are
tightened.
•If the Option is being used with
Size E1, care should be taken to
support the Option when the
terminal screws of the Option are
being tightened or loosened.
WARNING
•The ACS250/ACS255 and the
Options should be installed only
by qualified electrical persons and
in accordance with local and
national regulations and codes of
practice.
•Electric shock hazard!
Disconnect and ISOLATE the
drive before attempting any work
on it. High voltages are present at
the terminals and within the drive
for up to 10 minutes after
disconnection of the electrical
supply.
•Where the electrical supply to the
drive is through a plug and socket
connector, do not disconnect until
10 minutes have elapsed after
turning off the supply.

OPERATION
Programming the first relay output
Since the first relay output (fitted within the ACS250/ACS255 (115V-
480V Variant) is programmed using parameter 1401 in the drive,
two completely independent relay outputs are available. The
following options are supported for relay 1 :
1401
Relay 1 output function select (RO1)
0 : Drive enabled
1 : Drive healthy
2 : Motor at target speed
3 : Drive tripped
4 : Motor speed >= limit
5 : Motor current >= limit
6 : Motor speed < limit
7 : Motor current < limit
Defines the function of the user relay 1,
when the operating conditions are met.
Disabled : Contacts open
Enabled : Contacts closed
Options 4 to 7: the Relay output is
enabled using the level set in
parameter 3200
Programming the second relay output
The second relay output is controlled using parameter
1501. This can be set to any of the choices 0-7 as described below:
1501
Relay 2 output function select (RO2)
0 : Drive enabled
1 : Drive healthy
2 : Motor at target speed
3 : Drive tripped
4 : Motor speed >= limit
5 : Motor current >= limit
6 : Motor speed < limit
7 : Motor current < limit
Defines the function of the user relay 2,
when the operating conditions are met.
Disabled : Contacts open
Enabled : Contacts closed
Options 4 to 7 : the Digital output is
enabled using the level set in
Parameter 3200.
Note : Parameters 1401,1501, and 3200 are located in the Long
parameter group, group navigation is detailed in the drive manual.
NOTES
EXPLANATION
The Relay Output Module can be used in applications where the
analog/digital output from the drive is converted to a relay output.
Typical applications are where two relay outputs are required. The
functions of the relays are programmable in the drive and can be
any of the following:
oDrive enabled
oDrive healthy
oDrive at set speed
oDrive at zero speed
oDrive at max speed
oMotor in overload
OPTION CONTROL TERMINALS
* Analog inputs should be connected to terminals 6 & 7.
Note :
The second relay output contacts are available on terminals 8 and 9.
This relay utilises the drive’s analog/digital output for operation -
therefore the analog output is not available when this module is
fitted.
