After changing a parameter, press ENTER to confirm data when requested by the mes-
sage on the console. Parameters modified and optimized on one unit can be stored by the
console (SAVE) and then released (RESTORE) on another chopper, thus allowing fast and
standardized settings (see console manual for details).
(*) The acceleration time shown is the time from 0 Hz to 100 Hz. This is the ideal ramp
calculated by the software; the real ramp could change as a function of motor control
parameter setting and, obviously, as a function of the load.
(**) The braking feature is based upon deceleration ramps. The value shown in the table
is the time to decrease the speed from 100 Hz to 0 Hz. This is the ideal ramps calcu-
lated by the software; the real ramp could change as a function of motor control pa-
rameter setting and, obviously, as a function of the load.
