Closed-loop User Switches C1
110
The Ramp Down Enable Source parameter
(RAMP DOWN EN SRC(C1)) is used to select
one of the above options.
A method of providing the Ramp Down Enable
would be with a logic signal (EXTERNAL TB1)
that is dedicated to that function. The Ramp
Down Enable would be asserted while the Run
command is still present and remain there until
the ramp is completed, after which the Run
command would be removed.
The RUN LOGIC option to trigger the Ramp
Down Enable from the Run command is
provided. In this case, removal of the Run
command enables the Ramp Down Stop
Function.
The time it takes for the HPV 600 to perform its
ramped stop is determined by the Ramped Stop
Time Parameter. The Ramped Stop Time
parameter (RAMPED STOP TIME(A1)) selects
the amount of time it would take for the drive to
ramp from the rated torque to zero torque.
RAMP DOWN EN SRC
(Ramp Down Enable Source)
If RUN LOGIC is selected, the user can remove
the run command and the drive will delay in
dropping the run command until torque ramp
down stop function is complete.
If EXTERNAL TB1 or SERIAL is selected, the
user must keep the run command while allowing
the Torque Ramp Down Stop function to be
completed.
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.
EX TORQ CMD SRC
(Torque Command Source)
Sets the source of the external torque command
when the SPEED REG TYPE (C1) is set to
external reg.
NOTE:
•
if SPEED REG TYPE is set to external
reg and EX TORQ CMD SRC is set to
serial, the drive is a torque controller
•
if SPEED REG TYPE is set for a speed
regulator (either pi speed reg or elev
spd reg) and EX TORQ CMD SRC is set
to either serial, the torque command is
an auxiliary torque command (torque
feedforward command)
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.
S-CURVE ABORT
(S-Curve Abort)
This parameter, S-CURVE ABORT (C1),
addresses how the S-Curve Speed Reference
Generator handles a reduction in the speed
command before the S-Curve Generator has
reached its target speed.
Disabled
With a normal S-curve function, a change in the
speed command is never allowed to violate the
defined acceleration or jerk rates. If a reduction
in the speed command is issued before the S-
Curve generator has reached its target speed,
then the jerk rate dictates what speed is reached
before the speed may be reduced.
Enabled
The optional S-Curve abort has been selected.
In this case when the speed command is
reduced, the speed reference immediately starts
to reduce violating the jerk limit (thus no jerk out
phase), which could be felt in the elevator.
For optional S-Curve abort to be active requires
that:
•
The speed command source must be
selected as Multi-step (SPD COMMAND
SRC=multi-step).
