P41 LOAD SCALING
This scales the analog output signal at TB-30 and/or TB-31 when they are configured for a load output.
This setting is the load (in %) that is indicated when the output signal measures 10 VDC.
Example: A 0-10 VDC signal is required to indicate 0-150% load. Setting this parameter to 150% will
yield 10 VDC at 150% load.
P42 ACCEL / DECEL #2
This parameter sets the second acceleration and deceleration rate of the drive. To activate this
acceleration and deceleration rate, use terminal TB-13A, TB-13B or T-13C. TB-13A and TB-13B can
be set to AUXILIARY STOP which will cause the drive to decelerate to a stop according to the time
programmed in this parameter. TB-13C can be set to ACCEL/DECEL #2, which causes the drive to
accelerate and decelerate according to the time programmed in this parameter.
P43 SERIAL ADDRESS
If a serial link is being used to communicate with multiple drives, each drive must be given a different
address (from 1 to 247) so that an individual drive in the network can be accessed.
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
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 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.
05 RESET 50: Resets the user parameters to the factory defaults for a 50 Hz base frequency.
Parameters 24, 27, and 40 will reset to 50.0 Hz.
