UP / DOWN Command Operation
When the Forward Run command is active and the UP or Down command is momentarily activated the AC Drive 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).

: Acceleration/deceleration time selection. Toggle between Acce/Decel. Time 1 and Time 2. (00-14 to
00-17)
03-0X =11
: Inhibit Acceleration/deceleration command (hold command)
When activated function suspends the acceleration / deceleration operation and maintains the output frequency at
current level. For operation of inhibit Acceleration/deceleration function, please refer to figure below.
The frequency reference value is saved when the acceleration/deceleration inhibit command is active and the
frequency reference value is saved even when powering down the AC Drive.

: Main / Alternative Run Switch Function
When active, run command source is set to the alternative run command (00-03).
Note: Digital input function 27 (Local/ Remote control selection) has a higher priority than the main/alternative run
switch.

: Main/ Alternative Frequency Switch Function
When active, frequency command source is set to the alternative frequency command (00-06). When PID function is
active (10-03=XXX1B), this function is disabled and the frequency reference is set by the PID function. Note: Digital
input function 27 (Local/ Remote control selection) has a higher priority than the main/alternative run switch.
