NOTE
• If the user parameters are reset to the OEM defaults (using the RESET OEM option),
and then OPERATE WITH USER SETTINGS is selected, the USER settings will be the
same as the OEM default settings. This allows the drive to operate as if it was in
OEM mode, but the parameter values can be changed. This is useful if some of the
OEM default settings need to be fine-tuned for proper operation. The new parameter
values are not actually stored as new OEM default settings however; they are simply
stored as new USER settings. Therefore, if the parameters are reset to the OEM
defaults again, the parameters that were changed will be reset to their “old” value.
The optional EPM Programmer is required to change OEM default settings. Refer
to Section 4.2.2.
• Only the TRANSLATE (06) function can be performed while the drive is running. The
display will flash "Er" if an attempt is made to select any other function while the
drive is running.
P50 FAULT HISTORY
The FAULT HISTORY stores the last eight faults that tripped the drive. Refer to Section 5, Troubleshooting,
for a list of the faults and possible causes.
Use the p and q buttons to scroll through the fault entries. The faults are stored from newest to
oldest, with the first fault shown being the most recent.
The display will read “_ _” if the FAULT HISTORY does not contain any fault messages.
P51 SOFTWARE VERSION
Parameter P51 displays the software version number for the control board software. This information
is useful when contacting the factory for programming or troubleshooting assistance.
The software version is displayed in two parts which alternate. The first part is the software version,
and the second part is the revision number. For example, if the display flashes "94" and "02", this
indicates that the drive contains the second revision of version 94 software.
P52 DC BUS VOLTAGE
P52 displays the DC bus voltage in percent of nominal. Nominal DC bus voltage is determined by
multiplying the drive’s nameplate input voltage rating by 1.4.
P53 MOTOR VOLTAGE
P53 displays the output voltage in percent of the drive’s nameplate output voltage rating.
P54 MOTOR LOAD
P54 displays the motor load in percent of the drive’s output current rating.
