65: Up2 Command
Setting Function
65 Up2 Command
When you activate the terminal set for Up2 Command, the bias will increase. When you activate the terminal set
for Down 2 Command, the bias will decrease. When you activate or deactivate the two commands, the drive will
hold the frequency reference.
2 Command and d4-01, d4-03, d4-05.
Note:
• When using this function, set the optimal bias limit value with d4-08 and d4-09 [Up/Dw2 Bias Upper Limit and Up/Dw2 Bias Lower
Limit].
• Refer to "d4: FREQUENCY UP/DOWN" for more information.

more than d4-07 [Analog FRef Fluctuate
Limit], the drive holds the bias value until the
output frequency and the actual frequency
reference agree (speed agreement).
Storing the Frequency Reference or
Frequency Bias
Not stored.
When the bias value and frequency reference are
constant for 5 seconds after the frequency
reference hold starts, the drive will add the bias
value to the enabled frequency reference, then
reset.

When the bias value and frequency reference are
constant for 5 seconds after the frequency
reference hold starts, the drive will add the bias
value to the enabled frequency reference, then
reset.
Not stored.
When the bias value is constant for 5 seconds after
the frequency reference hold starts, the drive will
store the bias value in d4-06. You cannot rewrite
the frequency reference is not possible. The drive
will store only the bias value.
