Feature bit no. Description of the operation mode
Bit 0 0 • reserved, do not modify!
Bit 1 0/1 • 0: Counter inhibit with high-level at the gate input [0]
• 1: Counter inhibit with low-level at gate input
Bit 2, Bit 3 00 • Status input (active-low) is mapped into status byte 5 (ST.5) [00]
01 • reserved
10 • ST.5 = Status input, ST.6 = Status input
11 • ST.5 = Status input, ST.6 = !Status input
Bit 4 - Bit6 000 • External Latch function active [000]
001 • Period measurement active
010

• reserved
Bit 7 - Bit 9 0 • reserved, do not modify!
Bit 10, Bit 11 00 4-fold evaluation of the encoder signals A, B, C, i.e. both rising and falling edges of the encoder signals
A, B are counted. [00]
01 1-fold evaluation of the encoder signals A, B, C, i.e. each period of the encoder signal A is counted.
10 2-fold evaluation of the encoder signals A, B, C, i.e. each edge of the encoder signal A is counted.
11 4-fold evaluation of the encoder signals A, B, C
Bit 12 - Bit 14 0 • reserved, do not modify!
Bit 15 0/1 0: Encoder Interface [0]
1: Counter mode is active.
16-bit up/down counter
Input A: Counter
Input B: Counting direction (5 V or open = up, 0 V = down)
Input C: Latch
