P2.9.5.3 Zero speed time at start ID615
After giving the start command the drive will remain at zero speed for the time defined
by this parameter. The ramp will be released to follow the set frequency/speed
reference after this time has elapsed counted from the instant when the command was
given.
P2.9.5.4 Zero speed time at stop ID616
The drive will remain at zero speed with controllers active for the time defined by this
parameter after reaching the zero speed when a stop command is given. This parameter
has no effect if the selected stop function is Coasting . Note that the zero speed time
starts when the ramp time is expected to reach the zero speed, not when the actual
speed reaches zero. Such situation can happen when the generator power limit is small
or the overvoltage controller is active while decelerating.
