(see also Section 8, Sheet G136 and Section 9)

See P639 and P640 for ramp-function generator setting parameters

Mode for rounding the ramp-function generator

If the setpoint is reversed during ramp-up (or ramp-down),

acceleration (deceleration) is aborted and initial rounding of the

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).

If 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).

Ramp-down time of ramp generator with emergency stop (OFF3)

When the "Emergency stop" command is issued, the drive must normally

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 "Emergency stop" command is issued.
