UP / DOWN Command Operation
When the Forward Run command is active and the UP or Down command is momentarily activated the inverter
will accelerate the motor up to the lower limit of the frequency reference (00-13).
When using the UP / Down command, the output frequency is limited to the upper limit of frequency reference
(00-12) and the lower limit of frequency reference (00-13).
The UP / DOWN command uses acceleration 1 or 2 / deceleration time 1 or 2 for normal operation Tacc1 / Tdec1
(00-14, 00-15) or Tacc2 / Tdec 2 (00-16, 00-17).
