Tab. 7-19: Parameter list of hydraulic soft start
Soft start function is designed to reduce the p/Q command and acceleration
during start up period to minimize the too high of acceleration or potential over
current condition during start up. Once this function is active (set F4.20 > 0),
the p/Q commands and acceleration time will be switched to F4.21, F4.23 and
F4.25, in a time period of F4.20 after every run command.
Only when p/Q command soft start is active will the acceleration
time hydraulic soft start function be activated.
