When a rising signal edge is detected, a coun-ter will start being incremented every μs. Then, when the corresponding fall-ing signal edge is detected, the counter value will be recorded in the corre-sponding 16-bit PwmHighTime(x) count register. Once the value istransferred to PwmHighTime(x), the counter will be reset.Feature Description Value EDSName IncrementalEncoder1 3176 [MxSubExt317x]ParameterName=IncrementalEncoderxObjectType=0x7DataType=0x0006AccessType=roPDOMapping=1Count=1IncrementalEncoder2 3177Description Incremental Encoder Register xObject Code VARMapping PDOManualData type UNSIGNED16Sub index 01 … FE hexAccess ro1 Byte Byte 0:Sub index1≦n≦254B15B14B13B12B11B10B9B8B7B6B5B4B3B2B1B0MSBLSBn = n - 1Input xInput yn = n + 1Counter
