Here, you can determine the shape of
the travel curve by defining the times.
Acceleration ramp to speed V4
Deceleration ramp from V4 to standstill
in the case of direct landing. During deceleration to V0, the set value is
reduced proportionally to the ratio V4/V0.
Duration of deceleration ramp
"Electrical Stop". This ramp starts when the drive command V0 is
removed. The time EH defines when standstill is reached after V0 is removed.
Delay of start of travel curve after
the drive command is issued.
Time between closing of the brake and
switch-off of relay ZS (main contactor) during stopping.
Time between stopping (set value 0) and
closing of the brake (relay ZB switched off).
Time between issue of drive command and
opening of the brake (relay ZB switched on)
The ramps can be set either in
milliseconds or millimeters. If you want to set the units in milliseconds you
must enter additional system data (transmission, pulley-diameter and
suspension) correctly.

more details, please refer to the VVVF controller manual.
