The following describes the possible relay output settings:
NONE
This setting disables the relay output .
RUN
The relay energizes when the drive is given a START command, and remains
energized until: a STOP command is given and the output frequency has
decelerated to 0.5 Hz, the drive has “tripped”, or the input voltage is removed.
Note that this relay indicates only that the drive is in the RUN mode . It does not
necessarily indicate that the motor is turning .
FAULT
The relay energizes when input voltage is applied to the drive and remains
energized until the drive “trips” into a fault condition, or input voltage is removed.
/FAULT
INVERSE FAULT - The relay energizes when the drive trips into a fault
condition, and remains energized until the fault condition is cleared.
LOCK
FAULT LOCKOUT - This relay is used when the drive is programmed to
automatically restart after a fault. The relay energizes when input voltage is applied
to the drive and remains energized until the drive has faulted and unsuccessfully
attempted five restarts, or input voltage is removed .
@SPEED
AT SPEED - The relay energizes when the drive reaches the commanded
frequency. To avoid a “chattering” relay (constantly energizing and de-energizing),
due to small fluctuations in speed . the relay will change states only when the
actual speed and the speed set point differ by 3 Hz.
ABOVE #3
The relay energizes when the output frequency of the drive exceeds the value
corresponding to the SPEED #3 value, and de-energizes when the output
frequency returns to a value lower than the SPEED #3 value. See Parameter 3 -
SPEED #3 in Section 18 .0 - DESCRIPTION OF PARAMETERS .
I LIMIT
CURRENT LIMIT - The relay energizes when the drive is operating in
current limit. Once the current limit relay is energized, it remains energized for
a minimum of 500ms, regardless of whether the drive is still in current limit . At
the end of the 500ms interval, the relay will de-energize if the drive is no longer in
current limit . See Parameter 16 - CURRENT in Section 18 .0 - DESCRIPTION
OF PARAMETERS .
AUT/MAN
The relay energizes when the drive is in the AUTOMATIC mode, and
de-energizes in the MANUAL mode. Refer to Section 14.2.6 - SPEED
REFERENCE SELECTION .
