Open-loop User Switches C1
66
CONT CONFIRM SRC
(Contactor Confirm Source)
This switch selects if hardware confirmation of
motor contactor closure is necessary before
drive attempts to pass current through motor. If
hardware confirmation is available set to
EXTERNAL TB1 and select the Contact Cnfirm
signal on a logic input terminal.
FAULT RESET SRC
(Fault Reset Source)
This parameter determines the source of the
drive’s external fault reset from one of the
following sources: an external fault reset signal
from a logic input (external tb1), a fault reset
signal transferred across a serial channel
(serial), or the drive automatically resets the
faults (automatic). The user also has the option
to reset faults directly through the operator.
Automatic Fault Reset
If the fault reset source is set to automatic, the
faults will be reset according to the setting of the
FLT RESET DELAY (A1) and FLT
RESETS/HOUR (A1) parameters. When a logic
input is defined as “fault reset” and this logic
input signal is transitioned from false to true: an
active fault will be reset and automatic fault reset
counter (defined by FLT RESETS/HOUR(A1))
will be reset to zero.
CAUTION
If the run signal is asserted at the time of a fault
reset, the drive will immediately go into a run
state. Unless using the auto-fault reset function
(FAULT RESET SRC (C1)=automatic), then the
run command needs to be cycled to be reset
automatically, but will reset if initiated by a logic
input without cycling the run command.
OVERSPEED TEST SRC
(Overspeed Test Source)
This switch determines the source of the
overspeed test. Operation of the overspeed
test function is specified by the OVRSPEED
MULT (A1) parameter. Regardless of the
setting of this parameter, the user can call for
the overspeed test via the Digital Operator.
BRAKE PICK SRC
(Brake Pick Source)
If the BRAKE PICK SRC (C1) is set to
INTERNAL, the HPV 600 will attempt to pick (lift)
the brake when magnetizing current has been
developed in the motor.
BRAKE PICK CNFM
(Brake Pick Confirm)
If this switch is set to EXTERNAL TB1, the HPV
600 will wait for brake pick confirmation before
releasing the speed reference. When set to
EXTERNAL TB1, the MECH BRK PICK signal
on TB1 must also be selected.
BRAKE HOLD SRC
(Brake Hold Source)
If set to internal, the drive will command the
mechanical brake to hold mode until
confirmation of brake picked exists.
BRK PICK FLT ENA
(Brake Pick Fault Enable)
When this parameter is set to ENABLE, the
brake pick command and confirmation must
match within the specified time in BRK PICK
TIME (A1) parameter or a brake pick fault is
declared.
BRK HOLD FLT ENA
(Brake Hold Fault Enable)
When this parameter is set to ENABLE, the
brake hold command and confirmation must
match within the specified time in BRK HOLD
TIME (A1) parameter or a brake hold fault is
declared.
DIR CONFIRM
(Direction Confirm)
When enabled, the function allows confirmation
of the polarity of the initial analog speed
command via the Run Up or Run Down logic
input commands.
•
If the Run Up logic input is selected and true
with the polarity of the analog signal
positive, then the analog speed command is
accepted unchanged.
•
If the logic input Run Down logic input is
selected and true with the polarity of the
analog speed command negative, the
analog speed command is accepted
unchanged.
•
If however, the logic input Run Up is true
and the polarity is negative or the logic input
Run Down is true and the polarity is positive,
then the speed command is held at zero.
