P44 PASSWORD
This allows the PASSWORD to be changed to any number between 000 and 999. Setting PASSWORD
to 000 disables the password function.
NOTE: The factory default password is 225.
P45 SPEED AT MIN SIGNAL
This sets the speed at which the drive will run when it receives the minimum speed reference signal (0
VDC or 4 mA). This is used in conjunction with SPEED AT MAX SIGNAL (Parameter 46) to define
the speed range of the drive when following an analog speed reference signal.
P46 SPEED AT MAX SIGNAL
This sets the speed at which the drive will run when it receives the maximum speed reference signal (10
V DC 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
This 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 13.2.
01 OPERATE WITH USER SETTINGS: The drive will operate according to the users 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.
