STOPPING MODE
(Multi-step Stopping Mode Selection)
When the speed command source is set to
multi-step (SPD COMMAND SRC (C1)=multi-
step), the parameter, STOPPING MODE (C1),
determines the stopping mode of the HPV 600.
The two selectable methods for the Stopping
Mode parameter are “Immediate” and “Ramp to
stop”.
Note: If the SPD COMMAND SRC (C1)
parameter is set to any other definition other
than “multi-step”, the drive will behave to the
“immediate” stopping mode (independent of the
setting of the STOPPING MODE (C1)
parameter).
The “Immediate” stopping mode requires the
drive to be at zero speed prior to removing the
“Run” command. The “Immediate“ selection is
how the HPV 600 has traditionally behaved prior
to the addition of this parameter.
The “Ramp to stop” stopping mode is intended
for use when removing the “Run” command prior
to the drive reaching zero speed (as defined by
the AB ZERO SPD LEV (A1) parameter). When
the “Run” command is removed and the speed
reference is above zero speed, the speed
reference will ramp to zero speed following the
selected s-curve.
AUTO STOP
(Auto Stop Function Enable)
When the speed command source is set to
multi-step or serial (SPD COMMAND SRC
(C1)=multi-step or serial), the parameter
determines the stopping mode of the drive. The
two selectable methods for the STOPPING
MODE (C1)* parameter are “Immediate” and
“Ramp to stop”.
The Auto Stop function determines how the
drive logic will respond to a zero or non-zero
speed command. The function will only work
when the speed command source is either mult-
step or serial (SPD COMMAND SRC (C1)=multi-
step or serial).
Disabled
When the Auto Stop function is disabled, the
drive will be the act as the magnitude of the
speed command plays no part in the logical
starting or stopping of the drive.
Enabled
When the Auto Stop function is enabled and the
speed command source is either mult-step or
serial, the following changes occurs to the start
and stop sequence:
•
Both a Run command and a non-zero speed
command are required to start the drive
•
Either the removal of the Run command or
the setting the speed command to zero will
initiate a stop.
Remember, when the auto stop function is
enabled (AUTO STOP (C1)=enabled) both a
non-zero multi-step/serial speed command AND
the run command are required to start the drive.
It makes no difference which signal is enabled
first, the drive does not start until both are
present. When initiating a stop, which signal is
removed first does make a difference.
SERIAL MODE
(Serial Mode Selection)
This parameter selects between two serial
protocols.
The choices are:
•
Mode 1 – selects the Magnetek standard
protocol.
•
Mode 2 – selects a custom protocol.
•
Mode 2 Test – test mode used only when
testing custom protocol serial mode 2.
SER2 FLT MODE
(Serial Mode 2 Fault Mode)
Used only with custom serial protocol (mode 2)
This parameter defines the reaction to a serial
communications fault while in Serial Mode 2.
There are three possible settings:
o
Immediate – upon sensing a serial
communications fault while in the run
mode will result in an immediate stop.
The equivalent to removal of the “Drive
Enable” logic input.
o
Run Remove – upon sensing a serial
communications fault while in the run
mode, the drive will react in the same
manner that removal of the run
command would react. In this case, the
type of stop will be defined by the
STOPPING MODE (C1) parameter.
o
Rescue – upon sensing a serial
communications fault while in the run
mode, an attempt will be made to
continue to run at a low speed to the
next floor. Upon sensing the fault, the
drive will decelerate to a creep speed
and continue to run at that speed until
