EFKA AB286A5400 27
Example: Reaching the position is signalled by interrupt after a delay of 20ms
Step B Provide interrupt line 1 for slave by means of control byte 0F
No reception IRQ1 Interrupt Byte 0F Bit 0 - EIQ1 = 0
Transmit on IRQ1 Bit 1 - SIQ1 = 1
No reception IRQ2 Bit 2 - EIQ2 = 0
No transmission IRQ2 Bit 3 - SIQ2 = 0
With delay IRQ1 Bit 4 - ZIQ1 = 1
Bit 5 - TIQ1 = 1
Without delay IRQ2 Bit 6 - ZIQ2 = 0
Bit 7 - TIQ2 = 0
Master SOH ADR STX ($30 $46 $3D $33 $32) ETX BCC
Slave ADR ACK
Step C Selection of bit 2 in status byte 1 for triggering the interrupts, when position is reached.
Master SOH ADR STX ($30 $32 $3D $30 $34) ETX BCC
Slave ADR ACK
Step D Drive is to stop in position 2. Default options by means of control byte 04
No reset Control Byte 04 Bit 0 - RES = 0
Change direction of rotation Bit 1 - DRI = 1
Select speed 1 Bit 2 - V1 = 0
Bit 3 - V2 = 0
Drive is to stop in pos. 2 Bit 4 - STP1 = 1
Bit 5 - STP2 = 1
Bit 6 - STP3 = 0
Do not go to reference point Bit 7 - NPA = 0
Master SOH ADR STX ($30 $34 $3D $33 $32) ETX BCC
Slave ADR ACK
When bit 2 in status byte 1 changes from 0 to 1, time IRQ1 = 20ms starts and interrupt IRQ1 is triggered by the
slave.
The master can identify without polling whether the position has been reached, by receiving interrupt 1.

RDY = Drive is ready P3E = Position 3E reached STP1 = Stop bit 1
P01 = Is in position 1 P2A = Position 2A reached V2 = Speed bit 2
P02 = Is in position 2 P2E = Position 2E reached V1 = Speed bit 1
P0E = Position reached P1A = Position 1A reached DRI = Direction of rotation
DZE = Speed reached P1E = Position 1E reached RES = Software reset
STP = Motor at standstill NPA = Go to reference point
