Figure 1.37 Up/Down 2 Example with Other Reference than Digital Operator and d4-01 = 1
Note: Make sure to set the Up/Down 2 limits properly when using d4-01 = 1 in combination with the
Up/Down 2 function. Refer to
d4-08: Frequency Reference Bias Upper Limit (Up/Down 2) on
page 106 and d4-09: Frequency Reference Bias Lower Limit (Up/Down 2) on page 106 for
details on the limit settings.
Clearing the Value that was Saved
Depending on which function is used, the frequency reference value that was saved can be
cleared by:
• releasing the acceleration hold input
• setting an Up or Down command while no Run command is active.
■
d4-03: Frequency Reference Bias Step (Up/Down 2)
Sets the bias that is added to or subtracted from the frequency reference by the Up/Down 2
function.
The operation depends on the set value:
Setting d4-03 = 0.0 Hz
While the Up 2 or Down 2 command is enabled, the bias value is increased or decreased
using the accel/decel time determined by parameter d4-04.
