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 power supply .
TB15 OUT
53
This parameter sets the open-collector output indication for terminal TB-15 . It has the
same functionality as Parameter 52 - TB14 OUT above .
RELAY
54
The control board has one set of FORM C relay contacts that can be programmed for
the same indications as the open-collector outputs described above .
The FORM C relay contacts on TB-16, 17, and 18 are rated 2 Amps at 28 VDC or 120
Vac . Control wiring diagrams show relays in the rest state (coils NOT energized) .
TB5B LOSS
55
This parameter selects the action taken by the drive if the follower signal is lost at TB-5B .
This function is only active if the follower signal is 4-20 mA . The signal is considered lost
if it falls below 2 mA .

MIN ALARM - The relay de-energizes when the feedback signal
(in PID mode) or the speed reference signal (in open-loop speed
mode) equals or exceeds the MIN ALRM setting (Parameter 81),
and energizes when the signal falls below the MIN ALRM setting .
INVERSE MIN ALARM - The relay energizes when the feedback
signal (in PID mode) or the speed reference signal (in open-
loop speed mode) equals or exceeds the MIN ALRM setting
(Parameter 81), and de-energizes when the signal falls below
the MIN ALRM setting .
MAX ALARM - The relay de-energizes when the feedback signal
(in PID mode) or the speed reference signal (in open-loop speed
mode) is less than or equal to the MAX ALRM setting (Parameter
82), and energizes when the signal exceeds the MAX ALRM
setting .
INVERSE MAX ALARM - The relay energizes when the feedback
signal (in PID mode) or the speed reference signal (in open-loop
speed mode) is less than or equal to the MAX ALRM setting
(Parameter 82), and de-energizes when the signal exceeds the
MAX ALRM setting .
The relay energizes when Reverse direction is selected, and
de-energizes when Forward direction is selected .
The relay energizes when the drive is in SLEEP MODE . See
Parameters 36 - 38 .
The relay energizes when there is no output to the motor, for any
reason, such as: drive is in STOP mode, drive is in RUN mode
but the speed command is 0 Hz, drive is in SLEEP mode, drive
has tripped into a fault, etc .
(TB-15 OPEN COLLECTOR OUTPUT)
(RELAY FUNCTION)
(LOSS OF FOLLOWER ACTION)
The drive will go to the programmed minimum speed .
The drive will trip into a FOLLOWER fault condition .
The drive will go to SPEED #4 (Parameter 4) .
