S-Shape Characteristics; Time Unit Multiplier - GE VAT2000 Instruction Manual

B10-4

S-shape characteristics

Acceleration/deceleration with the S-shape pattern is possible by setting this parameter.
B 1 0-4 ts
This parameter indicates the time of the section shown as "ts" above.
The total acceleration/deceleration times ta and tb will not change.
When this parameter is set, all the acceleration and deceleration ramps available in the
VAT2000 will be S-type.
(Note)
B10-5

Time unit multiplier

The acceleration/deceleration time setting unit can be changed when an acceleration/
deceleration time in a wider range is to be set.
This parameter will affect all acceleration/deceleration time parameters.
