33 UNITS DP (SPEED UNITS DECIMAL POINT)
In “non-PID” mode, UNITS DP selects the decimal point location of the speed display.
UNITS DP has no effect if UNITS is set to sp HERTZ or sp % HZ.
In PID mode, UNITS DP selects the decimal point location for the PID SETPOINT and
FEEDBACK displays, and FB @ MIN and FB @ MAX.
The possible settings are: XXXXX, XXX.X, XX.XX, X.XXX, and .XXXX. Refer to the
above example in Parameter 32 - HZ MULT.
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.
