2.8 H: Terminal Function Selection
306 YASKAWA TOEPYAIGA5002A GA500 Programming
If you input the Run command before you turn ON the Drive Enable terminal, you must input the Run command
again to operate the drive. When you deactivate the terminal set for Drive Enable while the drive is operating, the
drive will use the stopping method set in b1-03 [Stopping Method Selection] to stop the motor.
ON : Run command is accepted.
OFF : Run command is disabled. When the drive is running, it stops according to b1-03 setting.
■ 75: Up 2 Command
Setting Value Function Description
75 Up 2 Command
Sets the function to increase the frequency reference bias value to accelerate the motor when the terminal is activated. Set this
function and H1-xx = 76 [Down 2 Command] together.
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. Table 2.53 gives information about the relation between operation of the Up/Down 2 Command
and d4-01, d4-03, and 4-05.
Note:
• When you use this function, set the optimal bias limit values with d4-08 and d4-09 [Up/Down 2 Bias Upper Limit/Lower Limit].
• Refer to d4: Frequency Ref Up/Down & Hold on page 234 for more information.

• 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 active or not 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 +
d4-03” (the bias value will increase to the value
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
Command are active or not active, the drive
holds the output frequency. (holds the bias
value).
• When the frequency changes, it will reset the
bias.

• When the Up 2 Command and Down 2
Command are active or not active, the drive
holds the output frequency (holds the bias value).
• During acceleration or deceleration, when the
frequency reference increases or decreases more
than d4-07, the drive holds the bias value until
the output frequency and the actual frequency
reference agree (speed agreement).

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.
