Torque Rate Limit
- Limits the rate of change of a torque command. The adjustable range is from
0-10.00 seconds. The factory preset is 0.00 seconds.
Custom Units Block
The custom units block parameters are used to set up a keypad Output Rate display of units that are
meaningful to your operation. The Output Rate display is only available if the Value At Speed
parameter has been changed from a value of 0. To see the Output Rate display press the Display
key until Output Rate is shown. The following parameters are used to set up the Output Rate
display:
Decimal places
- This parameter sets the maximum number of decimal places that will be shown I
the Output Rate keypad display. The Output Rate display is only available if the Value At Speed
parameter has been changed from a value of 0 . To see the Output Rate display depress the Display
key scrolling though the displays that are there until Output Rate is shown.
The number of decimal places will automatically be reduced for large values in the Output Rate
display. The actual number displayed is determined by the value programmed into the Value At
Speed parameter. The range of available decimal places is 0-5. The factory setting is 0.
Value at Speed
- Sets the desired output rate per RPM of motor speed. There are two numbers
displayed on the keypad that are separated by a slash. The left number is set first. It is the value
you want the keypad to display at a specific motor speed. Then set the right number to the RPM
corresponding to the units in the left number. A decimal may be inserted into the numbers by
placing the flashing cursor over the up/down arrow. The left and right numbers may range from 0-
65535. The factory set values are 0/0.
Units of Measure
- This parameter allows customization of the units of measure displayed in the
Output Rate display. To adjust, first select the character to be programmed by scrolling through the
available selection using the SHIFT key and the arrow keys.
If the desired selection is not shown in the character set in the display, move the flashing cursor to
the special Up/Down arrow character on the far left side of this keypad display using the SHIFT key.
Once the cursor is on the special Up/Down arrow character in the display, the Up/Down arrow keys
themselves can be used to select a different character set that will appear on the top line of the
keypad display. There are 9 different character sets that can be accessed. Now the desired
character can be programmed using the SHIFT and the arrow keys along with the ENTER key to
save your selection.
Protection Block
Overload
- This parameter setting determines if the control will trip off (FAULT), or automatically
reduce the output current below the continuous output level (FOLDBACK) if a motor overload
condition occurs. If "FAULT" is selected the control will need to be Reset if an overload condition
occurs and the control trips off. If continuous operation is desired, even in momentary overload
conditions, the control should be set to "FOLDBACK". If the Overload parameter is set to
"FOLDBACK" the output current will automatically reduce below the continuous output level until the
overload condition is corrected or eliminated. The factory preset is "FAULT".
