9. CONNECTION TO SERVO OR SPINDLE
Movement in the posi-
Movement in the negative
The differential input signals shown below are applied to the
connectors. The time duration, TD, from point α where the relative
potential difference between A and *A becomes 0.5 V or more, to
point β where the relative potential difference between B and *B
becomes 0.5 V or less, must satisfy the condition indicated below.
(This condition may restrict the maximum speed of movement.)
A / *A
*A / A
B / *B
*B / B
D Z–phase signal (Z, *Z)
The Z–phase signal (one–rotation signal) requires a signal width of
no less than one period of the A–phase or B–phase signal.
If the motor does not have this signal, ensure that the machine
supplies this signal.
An absolute pulse coder supports the following reference position
setting modes, which do not use the Z–phase signal:
1 External reference position setting
2 Butt–type reference position setting
