Number of accumulated MPG Input Pulses
1. Number of MPG input pulses is accumulated and stored by corresponding registers. The accumulated value is
plused by 1 when a forward pulse comes in, and minused by 1 when reverse pulse comes in.
2. The accumulated value is not affected by the electronic gear ratio (D1858 (D1938, D1918), D1859 (D1939,
D2019)).

Response Time of MPG Input
1. The faster the response time, the more synchronous between pulse output and MPG input.
2. The slower the response time, the more possible the pulse output lags behind MPG input.
