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 ofthe 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 AUTO/MANUAL MODE - The relay energizes when the drive is in the
AUTOMATIC mode, and de-energizes in the MANUAL mode. Refer to Section
14.2.5 - SPEED REFERENCE SELECTION.
FLWR PR FOLLOWER PRESENT - The relay energizes when the analog input reference signal
at TB-5B is greater than 2 mA, and de-energizes if the signal falls below 2 mA.
REVERSE The relay energizes when Reverse direction is selected, and de-energizes when Forward
direction is selected.
The open-collector output circuit is a current-sinking type rated at 30 VDC and 40 mA maximum. An
external power supply (30 VDC max.) must be used to power the open-collector outputs. The drive does
not have a dedicated power supply for the open-collector outputs.
53 TB15 OUT (TB-15 OPEN COLLECTOR OUTPUT)
This parameter sets the open-collector output indication for terminal TB-15. It has the same functionality
as Parameter 52 - TB14OUT above.
54 RELAY (RELAY FUNCTION)
The control board has one auxiliary relay which can be programmed to indicate one of the following
conditions: NONE, RUN, FAULT, /FAULT (INVERSE FAULT), LOCK (FAULT LOCKOUT), AT
SPEED, ABOVE #3, CURRENT LIMIT, or AUTO/MAN operation. Refer to Section 6.2 - DRIVE
FUNCTION DESCRIPTION for more detailed information.
The auxiliary relay has a set of FORM C contacts on TB-16, 17, and 18, rated 2 amps at 28 VDC or 120
VAC. Control wiring diagrams show relays in the rest state (coils NOT energized).
