Signal status, description
Find reference mark: Bit 7 = 0
Bit Meaning
0 Function 1: Homing using the encoder zero mark (except in "611U-compliant
mode")
1 Function 2: Homing using rising edge of external zero mark
2 Function 3: Homing using falling edge of external zero mark
3 Function 4: Not used
On-the-fly measurement: Bit 7 = 1
Bit Meaning
0 Function 1: Measuring using measuring probe 1 rising edge
1 Function 2: Measuring using measuring probe 1 falling edge
2 Function 3: Measuring using measuring probe 2 rising edge
3 Function 4: Measuring using measuring probe 2 falling edge
Note
• Bit 0 ... 3
Bit x = 1 Function requested
Bit x = 0 Function not requested
• If more than one function is enabled, the values for all functions cannot be read until
all functions have ended and this has been signaled via the relevant status bit
(G1_ZSW, Bit 0 - Bit 3 = 0).
• Find reference mark
A falling edge when homing using the external zero mark is not evaluated by SIN‐
UMERIK.
• Meas. on-the-fly
The rising and falling edges of the measuring input can be enabled simultaneously.
The measuring input signal is detected according to the direction of the signal
change. The measured values are read out consecutively.
Notice
ADI4 only supports measurement on a rising or falling edge.
• Find reference mark and on-the-fly measurement
Only one of the two functions can be active at a time.
