Instead, if “M2-13 Variable/Constant ramp time “CnRmpTm”” is set to 1, it would take 2 seconds to reach the
desired speed.
This means that the acceleration/deceleration slope changes with the active speed limit. In fact, continuing
from the previous example, if the Speed limit #1 (“M5.1-4 Cutback speed 1 “Speed1””) becomes active and is
set to 50Hz, it would take 0.5 seconds to reach the said speed with “M2-13 Variable/Constant ramp time
“CnRmpTm”” set to 0 (variable ramp time, constant slope) and 2 seconds with “M2-13 Variable/Constant ramp
time “CnRmpTm”” set to 1 (constant ramp time, variable slope).
The above applies for both acceleration and deceleration ramps.
Please notice that not all the speed limits are under the user’s control: some may in fact come from controller
internal limitation (i.e. temperature cutback, low voltage cutback, etc.). If constant ramp time is selected, the
set ramp times will be referred also to those limits, if they become active.
M2-14 Calibration data option “CalValue”
Not used.
M2-15 Load default ”LoadDefs”
If this parameter is set to 1 (load defaults) all the setting in all menus will be restored to the default factory
values.
This parameter requires a key cycle off-on to be effective.
