Function Group
Fixed scan time
Number
M1039, D1039
Contents:
1. When M1039 is ON, program scan time is determined by D1039. When program execution is
completed, next scan will be activated only when the fixed scan time is reached. If D1039 is
less than actual scan time, it will scan by the actual program scan time.

M1039
Fix scan time
Scan time is fixed to 20ms
2. Instructions related to scan time, RAMP, HKY, SEGL, ARWS and PR should be used with
“fixed scan time” or “timed interrupt”.
3. Particularly for instruction HKY, which is applied for 16-keys input operated by 4x4 matrix,
scan time should be set to 20ms or above.
4. Scan time displayed in D1010~D1012 also includes fixed scan time.
