mmand Is Given with Mult
i-Ste
p Speed
A frequency command is controlled with a signal pattern by setting multiple command frequencies in
advance.
In the multi-step speed command, one can either give a binary combination of 0 (OFF) and 1 (ON) or
give a priority on certain terminals (bit operation).
In the binary operation, a frequency at maximum 16th speed with four terminals can be set. In the bit
operation, a frequency at maximum 8th speed with seven terminals can be set.
Precautions for Correct Use
• If the LCD operator [AA101]=07 is chosen in the frequency command selection, rewriting of
the main speed command [FA-01] automatically rewrites [Ab110], frequency setting of the 0th
speed.
• The frequency setting for the 1st to 15th speeds should be made in the 1st-15th speeds of
the multi-step speed function ([Ab-11]-[Ab-25]).
• With the multi-step speed function, one can set the acceleration/deceleration time individu-
ally for the frequency switching in the multi-step speed command. For details, see
Switching of Acceleration or Deceleration Time with Multi-Speed Step
• The multi-step speed function is effective only for the main speed command. Not applied to
the auxiliary speed command
• If [SET] terminal is made ON and the secondary setting function is used, [Ab210] instead of
[Ab110] becomes effective.
