Times/Distances

 

 

 

Here, you can determine the shape of the travel curve by defining the times.

 

HL_V4

Acceleration ramp to speed V4

B_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.

EH

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.

SF

Delay of start of travel curve after the drive command is issued.

ZS

Time between closing of the brake and switch-off of relay ZS (main contactor) during stopping.

ZB_zu

Time between stopping (set value 0) and closing of the brake (relay ZB switched off).

ZB_auf

Time between issue of drive command and opening of the brake (relay ZB switched on)

 

 

Info

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.

 

For more details, please refer to the VVVF controller manual.
