1: A/B phase pulse input, run forward if the A-phase leads the B-phase by 90
degrees.
2: A/B phase pulse input, run forward if the B-phase leads the A-phase by 90
degrees.
3: Phase A is a pulse input and phase B is a direction input
(L = reverse direction, H = forward direction).
4: Phase A is a pulse input and phase B is a direction input
(L = forward direction, H = reverse direction).
5: Single-phase input
Position control: the PG2 pulse affects the PG1 pulse tracking position.
1. When PG2 is single-pulse, and PG1 is A/B phase pulse, the frequency of position control
should be (input pps*2) / (PG1 ppr *4) at constant speed.
2. When PG2 and PG1 are either single-pulse (or both A/B phase pulse), the frequency of
position control should be (input pps*2) / (PG1 ppr*2) at constant speed.
3. Due to the edge trigger of the pulse input, the input of A/B phase pulse should be read as 4
times of the frequency; and the single-phase input should be read as twice of the frequency.
For inputs with the same pps, the single-phase tracking frequency will be half of the
double-phase frequency.
Velocity control: PG2 acts according to the setting for Pr. 10-01 (PG1 ppr), and will not be
affected by PG1 pulse (single-phase input or A/B phase pulse). When the setting for Pr. 10-00, Pr.
