34 LOAD MLT
(LOAD MULTIPLIER)
This parameter is used to scale the % LOAD display. If the drive output current
rating is higher than the motor full load current rating, the drive will not display
100% load when the motor is at full load. Setting this parameter to the ratio (in %)
of the drive output current rating to the motor full load current rating will scale the
load display to show motor load instead of drive load. This will result in a display
of 100% when the motor is at full load.
The motor overload circuitry is also affected by this parameter. When the display
reads 150% load, the drive will trip on OVERLOAD in one minute, regardless of
the actual motor current. If this parameter is used to scale the display to show
actual motor load, then Parameter 17 - MOTOR OL should be left at 100%.
Likewise, if MOTOR OL has been set according to the motor full load rating, this
parameter should be left at 100%. Changing both parameters will result in an
OVERLOAD fault sooner than expected.
The output signal at TB-10B is also affected by this parameter. When set to the
ratio of current ratings as explained above, the output signal will be proportional
to motor load instead of drive load.
35 CONTRAST
(LCD DISPLAY CONTRAST)
This parameter is used to adjust the contrast of the drive display and can be set to
LOW, MED, or HIGH in order to obtain the most visible display. If the drive is
mounted lower than eye level, a HIGH setting may make the display more visible.
Likewise, if the drive is mounted higher than eye level, a LOW setting may make
the display more visible.
39 TB5 MIN
(TERMINAL TB-5 INPUT)
TB5 MIN selects the output frequency of the drive that will correspond to the
minimum analog speed reference input (0 VDC or 4 mA). This parameter is used
in conjunction with Parameter 40 - TB5 MAX to define a speed range for the drive
that corresponds to the analog speed reference input (0 - 10 VDC or 4 - 20 mA).
40 TB5 MAX
(TERMINAL TB-5 INPUT)
TB5 MAX selects the output frequency of the drive that will correspond to the
maximum analog speed reference input (10 VDC or 20 mA). This parameter is
used in conjunction with Parameter 39 - TB5 MIN to define a speed range for the
drive that corresponds to the analog speed reference input (0 - 10 VDC or 4 - 20
mA).
