Select three terminals for Up/Down operation and set them to 17
(Up), 18 (Down) and 27 (U/D Enable), respectively.
When the U/D Enable input and the Up input are activated, the
inverter will accelerate. When the Up input is De-activated, the
acceleration will stop and inverter will operate at a constant speed.
When the U/D Enable input and the Down input are activated, the
inverter will decelerate. When the Down input is De-activated, the
deceleration will stop and inverter will operate at a constant speed.
When both Up and Down inputs are activated, the inverter will
operate at a constant speed.
If the U/D Enable input is not activated, acceleration/deceleration will
follow the speed reference set in the Frq parameter.
If the U/D Enable input is activated during normal
acceleration/deceleration, acceleration/deceleration will stop and
the inverter will wait for Up or Down inputs.
When set to Yes, the operating frequency is saved automatically in
the following conditions: the run command (Fx or Rx) is removed, a
fault occurs, or the inverter is powered off.
When the run command is reapplied, or when the fault is cleared, or
when power is restored, the inverter resumes operation at the saved
frequency.
To delete the saved frequency, set one of the multi-function (digital)
terminals to 20 (U/D Clear) and activate the input during constant
speed operation. The saved frequency will be deleted.
