06 TRANSLATE: If an EPM from a drive with a previous 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.
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. (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 far left digit of the display will
be the fault number and the remaining two digits will be the fault code. 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
This 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 shows "64-" and "-02", this
indicates that the drive contains the second revision of version 64 software.
P52 DC BUS VOLTAGE
This 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
This displays the output voltage in percent of the drive’s nameplate output voltage rating.
P54 MOTOR LOAD
This displays the motor load in percent of the drive’s output current rating.
