Note: 1. An oPE03 alarm will occur when only one of the functions Up/Down is programmed for a digital input.
2. An oPE03 alarm will occur if the Up/Down function is assigned to the terminals while another input is programmed for the Accel/
Decel Ramp Hold function. For more information on alarms,
3. The Up/Down function can only be used for external reference 1. Consider this when using Up/Down and the external reference
switching function (H1- = 2).
Using the Up/Down Function with Frequency Reference Hold (d4-01)
• When the frequency reference hold function is disabled (d4-01 = 0), the Up/Down frequency reference will be reset to
0 when the Run command is cleared or the power is cycled.
• When d4-01 = 1, the drive will save the frequency reference set by the Up/Down function. When the Run command or
the power is cycled, the drive will restart with the reference value that was saved. The value that was saved can be reset
by closing either the Up or Down input without having a Run command active.

Using the Up/Down Function with Frequency Reference Limits
The upper frequency reference limit is determined by parameter d2-01.
The value for the lower frequency reference limit depends on the setting of parameter d4-10 and can be set by an analog
input or parameter d2-02. Refer to d4-10: Up/Down Frequency Reference Limit Selection on page 141
a Run command is applied, the lower limits work as follows:
• If the lower limit is set by parameter d2-02 only, the drive will accelerate to this limit as soon as a Run command is
entered.
• If the lower limit is determined by an analog input only, the drive will accelerate to the limit as long as the Run command
and an Up or Down command are active. It will not start running if only the Run command is on.
• If the lower limit is set by both an analog input and d2-02, and the analog limit is higher than the d2-02 value, the drive
will accelerate to the d2-02 value when a Run command is input. Once the d2-02 value is reached, it will continue
acceleration to the analog limit only if an Up or Down command is set.
Figure 5.46 shows an Up/Down function example with a lower frequency reference limit set by d2-02 and the frequency
reference hold function enabled/disabled.
Setting 12/13: FJOG/RJOG Reference
Digital inputs programmed as Forward Jog (H1- = 12) and Reverse Jog (H1- = 13) will be Jog inputs that do not
require a Run command. Closing the terminal set for Forward Jog input will cause the drive to ramp to the Jog Frequency
Reference (d1-17) in the forward direction. The Reverse Jog will cause the same action in the reverse direction. The
Forward Jog and Reverse Jog command can be set independently.
Note: The Forward Jog and Reverse Jog commands override all other frequency references. However, if the drive is set to prohibit reverse
rotation (b1-04 = 1), then activating Reverse Jog will have no effect. If both the Forward Jog and Reverse Jog are input simultaneously
for 500 ms or more, an external fault will occur and the drive will stop using the method set by b1-03.
