• When the Up 2 Command is active, the drive
accelerates the motor (increases the bias value).
• When the Down 2 Command is active, the drive
decelerates the motor (decreases the bias value)
• When the Up 2 Command and Down 2
Command are not active and when the Up 2
Command and Down 2 Command are active, the
drive holds the output frequency (holds the bias
value).
• When the frequency changes, it will reset the
bias.
• For all other statuses, the drive will follow the
frequency reference.

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 Up 2 Command is active, the drive
accelerates the motor to “Frequency Reference +

set in d4-03)
• When the Down 2 Command is active, the drive
decelerates the motor to “Frequency Reference -
d4-03” (the bias value will decrease to the value
set in d4-03).
• When the Up 2 Command and Down 2

the output frequency and the actual frequency
reference agree (speed agreement).

■ 76: Down 2 Command
Setting Value Function Description
76 Down 2 Command
Sets the function to decrease the frequency reference bias value to decelerate the motor when the terminal is activated. Set this
function and H1-xx = 75 [Up 2 Command] at the same time.
