NOTE: When set to CLEAR, TB-13D becomes the only terminal that can be
used to clear a fault (TB-1 will not work). However, the keypad STOP key can
still be used to clear faults.
52 TB14 OUT (TB-14 OPEN COLLECTOR OUTPUT)
This parameter sets the open-collector output indication for terminal TB-14. The
following conditions can be selected: NONE, RUN, FAULT, / FAULT (INVERSE
FAULT), LOCK (FAULT LOCKOUT), AT SPEED, ABOVE #3, I LIMIT
(CURRENT LIMIT), or AUTO/MAN operation. Refer to Section 6.2.5 -
MC1000 STATUS OUTPUT RELAYS.
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 - TB14 OUT 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, I LIMIT (CURRENT
LIMIT), or AUTO/MAN operation. Refer to Section 6.2.5 - MC STATUS
OUTPUT RELAYS.
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).
57 SERIAL (SERIAL COMMUNICATIONS)
This parameter is used to activate serial communications. When using this feature,
the drive can communicate with a personal computer (PC), programmable logic
controller (PLC), or other external device that utilizes RS-485 serial communications
for control. The serial interface may be used to read present parameter settings
(uploading to the control device), write new parameter settings (downloading
from the control device), monitor present drive activity, and control drive activity.
The following settings are available:
