Inverter Functions
12.4.10
Multi-step switching of frequency
commands.
• Want to use signal input to make multi-step
switching of the output frequency of the inverter.
• 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 max. 16th
speed with four terminals can be set. In the bit
operation, a frequency at max. 8th speed with seven
terminals can be set.
Parameters
• If the operator keypad [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 individually for the
frequency switching in the multi-step speed
command. For details, see “12.8.3 Setting
acceleration/deceleration time in multi-step speed”
• 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.
