MIN ALR 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.
/ MIN ALR 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 ALR 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.
/ MAX ALR 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.
REVERSE The relay energizes when Reverse direction is selected, and
de-energizes when Forward direction is selected.
SLEEP The relay energizes when the drive is in SLEEP MODE. See
Parameters 36 - 38.
SPD = 0HZ 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.
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.
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 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).
55 TB5B LOSS (LOSS OF FOLLOWER ACTION)
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.
NONE The drive will go to the programmed minimum speed.
FAULT The drive will trip into a FOLLOWER fault condition.
SP #4 The drive will go to SPEED #4 (Parameter 4).
