1. Speed feedback selection in full closed loop control
Full closed loop control is usually set to "use motor encoder speed (P9-01.0 = 0).". When
connecting only the direct driving servo motor and the high-resolution grating ruler, please set it to "use
grating ruler speed (P9-01.0 = 1)".
2. Z-phase signal source
P9-01.1 determines the z-phase source of the return to zero process.
3. Servo pulse output
Motor encoder phase ABZ output
Grating ruler ABZ output waiting for positioning completion
P9-01.2 determines the signal source of servo pulse output.

1. Mechanical side grating scale frequency division
=
Motor encoder feedback pulse per turn
External quadrature encoder pulse per turn
=
P9-06*10000+P9-05
P9-08*10000+P9-07
Motor encoder feedback pulse per turn = P9-06*10000+ P9-05. When the set value = 0, the resolution
of the encoder is set to the frequency division numerator.
Grating ruler feedback pulse per turn = P9-08*10000+ P9-07, P9-08*10000+ P9-07. When the setting
value = 0, set 10000 as the frequency division denominator.
Input the frequency division ratio of external grating ruler completely, cannot input it after reducible
division.
2. In the full closed-loop mode, it is recommended that P0-11 and P0-12 be set to 0, and the
electronic gear ratio of P0-13 and P0-14 is adopted. P0-11 and P0-12 can also be used on the premise
that the frequency division of external grating ruler is correct, otherwise, E-236 will be alarmed.
