142 Application macros
Sequential control macro
The Sequential control macro is suited for speed control applications in which a
speed reference, multiple constant speeds, and two acceleration and deceleration
ramps can be used.
Only EXT1 is used in this macro.
The macro offers seven preset constant speeds which can be activated by digital
inputs DI4…DI6 (see parameter
). An external speed
reference can be given through analog input AI1. The reference is active only when
no constant speed is activated (digital inputs DI4…DI6 are all off). Operational
commands can also be given from the control panel.
The start/stop commands are given through digital input DI1; running direction is
determined by DI2.
Two acceleration/deceleration ramps are selectable through DI3. The acceleration
and deceleration times, as well as ramp shapes, are defined by parameters
…

The figure below shows an example of the use of the macro.
