6-7-3 Switching of Acceleration or Deceleration Time with Multi-Speed Step
Setting up this function allows the acceleration or deceleration time to be changed in response to the
multi-speed command.
Also this function changes several settings of acceleration/deceleration times while the motor is being
accelerated to reach the fixed frequency.
Precautions for Correct Use
• When using the input terminal function to switch the multiple speeds, operation should be
performed by assigning 003 [CF1] to 006 [CF4] or 007 [SF1] to 013 [SF7] to any of [CA-01] to
[CA-11].
• When [AC-02] Acceleration/ Deceleration Selection is 01, the 2-stage acceleration or decel-
eration function is disabled.
