003 Local/Remote Control (HAND-O-AUT)
Value:
★
Use keypad (KEYPAD HOA)
[0]
✔
Use keypad with external stop (KEY HOA w. stp)
[1]
External HOA (EXTERNAL HOA)
[2]
Function:
There is a choice of three different Local/Remote control
modes for controlling the drive. Use
External H-O-A when
remote switching between “Hand” (manual operation) and
“Auto” (control via general control system) is to be used. If
External H-O-A is chosen, the “Local/Hand” key cannot be
used directly on the control panel of the drive.
Description of choice:
If
Use keypad [0] is selected, the speed can be con-
trolled directly on the control panel of the drive by activating
the “Local/Hand” key. The “Stop” key is active on the control
panel of the drive, unless it has been defeated by param-
eter 007. When shifting between “Local/Hand” and “Re-
mote/Auto”, the local speed reference will not be saved.
If
Use keypad with external stop [1] is selected, the drive
can be stopped by breaking the connection between termi-
nal 12 (24 V DC) and terminal 27. Terminal 27 must be pro-
grammed for
Coast stop [0] or Reset and Coast Stop [3] in
parameter 404.
If
External H-O-A [2] is selected, it is possible to change
between “Hand” (manual operation) and “Auto” (control
from general control system) via the control terminals of the
drive, as programmed in parameters 400 through 403.
“Latch Start Hand” is programmed in parameter 403 or 405.
The reference type for “Hand” control is selected in param-
eter 420.
004 Local Reference (LOCAL SPEE)
Value:
00.00 to f
MAX
Function:
A local reference can be programmed in parameter 004. If
the programmed local reference is to be active, the “Local/
Hand” key must have been pressed. To ensure smooth op-
eration, each time the drive is placed into “Local/Hand” from
the “Remote/Auto” mode, the local speed reference is reset
to match the drive’s present speed. The local speed refer-
ence is retained after the “Stop” key is pressed, as long as
the drive stays in the “Local/Hand” mode.
Description of choice:
The speed can be set directly in Hz. The set value is saved
after 20 seconds. The setting is saved even after power is
removed, but it is not saved when the drive is switched to
“Remote/Auto” mode. The local reference cannot be con-
trolled via serial communication. Data changes in param-
eter 004 are blocked if parameter 010 is programmed as
DISABLE.
WARNING
!
The motor may start without warning if parameter 014 is
changed to Auto restart [0] and a value is entered into pa-
rameter 004.
005 User Readout (VALUE AT M)
Value:
1 to 9999
★
100
Function:
Select the desired maximum value of the unit chosen by
parameter 117. This will typically be “100” for % speed,
“1750” for RPM, etc. Parameter 101 must be set to “Open
Loop” to access this function.
Description of choice:
The programmed value will be displayed when the output
frequency is equal to f
MAX
(parameter 202).
006 Local Reset (LOCAL RESE)
Value:
Not possible (DISABLE)
[0]
★
Possible (ENABLE)
[1]
Function:
