PARAMETER DESCRIPTION COMMENTS
P50 Fault History This parameter lists the last 8 faults that tripped the drive. Use the up
and down arrow buttons to scroll through the faults. The left hand digit of
the display is the fault number. The remaining two digits are the fault
code. Fault codes are defined in Table 71. Faults are stored from most
recent to older faults; for example, 1xx, 2xx, 3xx, etc., where “xx” is the
Fault Code listed in Table 71. The display will read “ - -” if the Fault His-
tory is empty.
P51 Software Version This parameter is the software version for the Motormaster V controller.
The software version is displayed in two parts. The first part is the soft-
ware version. The second part is the revision number.
P52 DC Bus Voltage This parameter value indicates the DC bus voltage in percent of nominal.
Nominal DC bus voltage is determined by multiplying the drive’s name-
plate input voltage rating by 1.4.
P53 Motor Voltage This parameter displays the output voltage in percent of the drive’s
nameplate output voltage rating.
P54 Motor Load This parameter displays the motor load in percent of the drive’s output
current rating.
P55 0 to 10 vdc Analog Input This parameter indicates the level of the 0 to 10 vdc analog input signal
at TB-5. A value of 100% indicates a 10 vdc at TB-5.
P56 4 to 20 mA Input Analog Input This parameter indicates the level of the 4 to 20 mA analog input signal at
TB-25. A value of 20% indicates a 4 mA input at TB-25. A value of 100%
indicates a 20 mA at TB-25.
P57 Terminal Strip Status This parameter indicates the status of several terminals using vertical
segments of the LED display. An illuminated segment indicates that the
terminal is closed with respect to TB-2. The Charge Relay is not a termi-
nal and should always be illuminated. See the diagram below for seg-
ment meanings.
P58 Keypad and Protection Status This parameter indicates the status of the buttons on the keypad and the
status of the protective circuitry in the drive, using the horizontal seg-
ments of the LED display. An illuminated segment indicates that the but-
ton is depressed and the protective circuit is active. See the diagram
below for segment meanings.
P59 TB-30 Analog Output This parameter displays the level of the analog output at TB-30. A value
of 100% indicates a 10 vdc. This output is not used on 38AP units.
P60 TB-31 Analog Output This parameter displays the level of the analog output at TB-31. A value
of 100% indicates a 10 vdc. This output is not used on 38AP units.
