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:
o
Drive enabled
o
Drive healthy
o
Drive at set speed
o
Drive at zero speed
o
Drive at max speed
o
Motor in overload

* 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.

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
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
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:
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
Note : Parameters 1401,1501, and 3200 are located in the Long
parameter group, group navigation is detailed in the drive manual.
