selection
• Set this parameter to limit the motor rotation to only one direction.
• This parameter is valid for all of the reverse rotation and forward rotation keys of the operation panel and of the parameter
unit, the start signals (STF, STR signals) via external terminals, and the forward and reverse rotation commands through
communication.
5.9.5
Frequency setting via pulse train input
A pulse train input to the terminal JOG can be used to set the inverter's speed command.
Moreover, speed synchronized operation of an inverter can be performed by using the pulse train output together with
the terminal JOG.
