P46 SPEED AT MAX SIGNAL
P46 sets the speed at which the drive will run when it receives the maximum speed reference signal
(10 VDC or 20 mA). This is used in conjunction with SPEED AT MIN SIGNAL (Parameter 45) to define
the speed range of the drive when following an analog speed reference signal.
NOTE
If SPEED AT MIN SIGNAL is set higher than SPEED AT MAX SIGNAL, the drive will react
inversely to the speed reference signal. Therefore, as the speed reference signal increases,
the drive speed will decrease, and vice-versa.
P47 CLEAR FAULT HISTORY
01 MAINTAIN: Maintains the FAULT HISTORY (Parameter 50) entries for troubleshooting.
02 CLEAR: Erases the FAULT HISTORY (Parameter 50) entries.
P48 PROGRAM SELECTION
P48 is used to select whether the drive will operate according to the user settings or the optional OEM
default settings, and to reset the parameters to default settings. Refer to Section 4.2.2.
01 OPERATE WITH USER SETTINGS: The drive will operate according to the user settings. Operation
in USER mode allows the parameter values to be changed to suit any application.
02 OPERATE WITH OEM DEFAULTS: The drive will operate according to the optional OEM default
settings, which configure the drive for a specific application. When operating in OEM mode, the
parameter values can be viewed, but not changed. If an attempt is made to change a parameter
setting, the display will flash “GE”. If the drive is not programmed with OEM default settings,
the display will flash “GF” if this option is selected.
03 RESET OEM: Resets the user parameters to the OEM default settings. If the drive is not
programmed with OEM default settings, the display will flash “GF” if this option is selected.
04 RESET 60: Resets the user parameters to the factory defaults for a 60 Hz base frequency.
Parameters 24, 27, and 46 will reset to 60.0 Hz.
05 RESET 50: Resets the user parameters to the factory defaults for a 50 Hz base frequency.
Parameters 24, 27, and 46 will reset to 50.0 Hz.
06 TRANSLATE: If an EPM from a drive with a previous (but compatible) parameter version is
installed in a new drive, the new drive will function like the previous version drive, but none
of the parameter settings can be changed ("cE" will be displayed if this is attempted). The
TRANSLATE function converts the EPM to the new parameter version so that the parameters
can be changed, but it also retains the old parameter settings so the new drive will operate like
the old drive without having to re-program all of the parameters. Once the EPM is "translated",
it will no longer work in the old drive.
