% S–Ramp
Percentage of ramp with S–shaped rate of change. A value of zero is equivalent to a linear ramp.
Changing this value affects the ramp times.
Range: 0.00 to 100.00 %
Ramping Thresh.
Ramping flag threshold level. The threshold is used to detect whether the ramp is active.
Range: 0.00 to 100.00 %
Auto Reset
If true, then the ramp is reset whenever System Reset is true, that is each time the speed/current
loop is unquenched. (System Reset [374] is an internal flag that is set true for one cycle after the
speed/current loop is enabled, i.e. every time the drive is started).
Range: 0 : Disabled
1 : Enabled
External Reset
If true, then the ramp is held in reset. External reset does not depend on auto reset for its operation.
Range: 0 : Disabled
1 : Enabled
