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 1 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 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.

  • For all other statuses, the drive will follow the frequency reference.

  • 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).

  • 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).
