Scaling of position values
The safety module stores the motor encoder and, if necessary, the position encoder position as 32-
bit values. The lower-order 16 bits contain the fraction of a motor revolution and the higher-order
16 bits contain the multiple of a motor revolution.
Example Calculation Result (hex)
¼ motor revolution 65536 / 4 = 16384 0x0000'4000
½ motor revolution 65536 / 2 = 32768 0x0000'8000
1 motor revolution 1 * 65536 = 65536 0x0001'0000
2 motor revolutions 2 * 65536 = 131072 0x0002'0000
2½ motor revolutions 2 * 65536 + 65536 / 2 = 163840 0x0002'8000
