P295	Mode for rounding the ramp-function generator		[SW 1.9 and later]
FDS	0	If the setpoint is reversed during ramp-up (or ramp-down),
		acceleration (deceleration) is aborted and initial rounding of the
(G136)		deceleration (acceleration) process begins immediately. The
		setpoint is not increased (decreased) any further, but the signal
		at the ramp-function generator output has a breakpoint (i.e. a
		step change in the acceleration rate).

1If the setpoint is reversed during ramp-up or ramp-down, acceleration/deceleration gradually changes to deceleration/acceleration. The setpoint increases/decreases further, but there is no breakpoint in the signal at the generator output (i.e. there is no step change in the acceleration rate).

P296	Ramp-down time of ramp generator with quick stop (OFF3)
FDS	[SW 1.9 and later]
	When the "quick stop" command is issued, the drive must normally
(G136)
	brake down to 0 speed along the current limit. If the mechanical design of
	the drive makes this option impermissible or undesirable, then a value of > 0
	can be set here. In this case, the drive brakes along the deceleration ramp
	programmed here when the "quick stop" command is issued.
