(3) Improved functions available with HRV control
The use of servo software supporting HRV control replaces the current
control method with HRV control as described above, and can improve
control performance. In addition, the functions below can be optimized
by modifying the settings.
<1> OVC alarm
In the medium time range (20 to 60 s), the current OVC alarm
characteristics are relatively overprotective with respect to the
characteristics of the servo motor and servo amplifier to be
actually protected.
To make full use of the capabilities of the servo motor and servo
amplifier, HRV control provides a function for matching with the
characteristics of the actually used servo motor and servo
amplifier by loosening the level of the medium time range of the
OVC alarm. (See Fig. 4.2.)
To use this function, the following parameter needs to be set:
#7 #6 #5 #4 #3 #2 #1 #0
