Detailed descriptions
LOGIC INPUT x
(Logic Inputs 1-9)
This parameter defines the function of the logic
inputs.
NOTE: The user can assign particular functions
to each input terminal. Only one function per
terminal is allowed and multiple terminals cannot
have the same function. When a function is
assigned to an input terminal, it is removed from
the list of possible selections for subsequent
terminals.
NOTE: The
current
setting of each parameter is
displayed in all caps; all other choices in the list
are displayed in lower case.
Choices
contact cfirm
(Contact Confirm Signal)
Closure of the auxiliary contacts confirming
closure of the motor contactor.
drive enable
(Drive Enable)
Enables drive to run. This signal must be
asserted to permit drive to run. This does not
initiate run, just permits initiation.
extrn fault 1
(External Fault 1)
extrn fault 2
(External Fault 2)
extrn fault 3
(External Fault 3)
Closure of this contact will cause the drive to
declare a fault and perform a fault shutdown.
extrn /flt 4
(External /Fault 4)
Opening of this contact will cause the drive to
declare a fault and perform a fault shutdown.
fault reset
(Fault Reset)
If the FAULT RESET SRC (C1) switch is set to
EXTERNAL TB1, the drive’s fault circuit will be
reset when this signal is true. If the FAULT
RESET SRC (C1) switch is set to AUTOMATIC,
the drive’s fault circuit will be reset when this
signal is true and the automatic fault reset
counter (defined by FLT RESETS/HOUR(A!))
will be reset to zero.
NOTE: This input is edge sensitive and the fault
is reset on the transition from false to true.
low gain sel
(Low Gain Select Signal)
If the HI/LO GAIN SRC (C1) switch is set to
EXTERNAL TB1, the low gain mode is chosen
for the speed regulator when this signal is true.
mech brk hold
(Mechanical Brake Hold Signal)
Auxiliary contact closures confirming when the
mechanical brake is in the hold mode
(engaged).
mech brk pick
(Mechanical Brake Pick Signal)
Closure of auxiliary contacts confirming the
mechanical brake has been picked (lifted).
no function
(No Function)
When this setting is selected for one of the TB1
input terminals, any logic input connected to that
terminal will have no effect on drive operation.
ospd test src
(Overspeed Test Source)
This function works only if the OVRSPEED
TEST SRC (C1) switch is set to EXTERNAL
TB1. A true signal on this input applies the
OVERSPEED MULT to the speed command for
the next run. After the run command has
dropped, the drive returns to ‘normal’ mode and
must be re-configured to perform the overspeed
function again. The OVERSPEED FLT level is
also increased by the OVERSPEED MULT,
allowing the elevator to overspeed without
tripping out on an overspeed fault.
NOTE: This input must be taken false then true
each time that an overspeed test is run. If the
input is left in the true, it is ignored after the first
overspeed test.
pre-trq latch
(Pre-Torque Latch)
Closing a contact between this input and ground
latches the pre torque command present on the
analog channel.
run
(Run)
If drive is enabled through the DRIVE ENABLE
logic input, this function will start drive operation.
run down
(Run Down)
If drive is enabled through the DRIVE ENABLE
logic input, this function will start drive operation
with negative speed commands.
Note: if both RUN UP and RUN DOWN are true
then the run is not recognized.
Note: if DIR CONFIRM (C1) is enabled, this
input will not change the polarity of the speed
command and will be used to confirm the
polarity of the analog speed command as well
as starting the operation of the drive.
