100 Application macros
Hand/Auto macro
The Hand/Auto macro is suited to speed control applications where two external
control devices are used.
The drive is speed-controlled from the external control locations EXT1 (Hand control)
and EXT2 (Auto control). The selection between the control locations is done through
digital input DI3.
The start/stop signal for EXT1 is connected to DI1 while running direction is
determined by DI2. For EXT2, start/stop commands are given through DI6, the
direction through DI5.
The reference signals for EXT1 and EXT2 are connected to analog inputs AI1 and
AI2 respectively.
A constant speed (by default, 300 rpm) can be activated through DI4.
