92 Application macrosHand/Auto macroThe Hand/Auto macro is suited for speed control applications where two externalcontrol devices are used.The drive is speed-controlled from the external control locations EXT1 and EXT2.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 isdetermined by DI2. For EXT2, start/stop commands are given through DI6, thedirection through DI5.The reference signals for EXT1 and EXT2 are connected to analog inputs AI1 andAI2 respectively.A constant speed (300 rpm) can be activated through DI4.Default parameter settings for Hand/Auto macroBelow is a listing of default parameter values that differ from those listed in chapterAdditional parameter data (page 263).Parameter Hand/Auto macrodefaultNo. Name10.01 Ext1 start func In1St In2Dir10.03 Ext1 start in2 DI210.04 Ext2 start func In1St In2Dir10.05 Ext2 start in1 DI610.06 Ext2 start in2 DI510.10 Fault reset sel C.FALSE12.01 Ext1/Ext2 sel DI313.05 AI1 min scale 0.00013.09 AI2 max scale 1500.00013.10 AI2 min scale 0.00021.02 Speed ref2 sel AI2 scaled21.04 Speed ref1/2 sel DI326.02 Const speed sel1 DI426.06 Const speed1 300 rpm
