6.2.5 AC400 STATUS OUTPUT RELAYS
The control board has one Form C relay at terminals TB-16, TB-17, and TB-18. Contacts
are rated for 2 amps at 28 VDC or 120 Vac.
There are also two open-collector outputs at terminals TB-14 and TB-15. The open-collector
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.
The Form C relay and the open-collector outputs can be programmed to indicate any of the
following: RUN, FAULT, /FAULT (INVERSE FAULT), LOCK (FAULT LOCKOUT), @
SPEED (AT SPEED), ABOVE #3, I LIMIT (CURRENT LIMIT), AUTO/MAN mode,
FLWR PR (FOLLOWER PRESENT), or MIN/MAX (MIN/MAX ALARM). See
Parameters: 52 (TB14 OUT), 53 (TB15 OUT), and 54 (RELAY), in Section 18.0 -
DESCRIPTION OF PARAMETERS.
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.
