: User constants that must be always set
1) Internal speed selection is valid only when bit 2 of Cn-02 is set to "1."
2) The factory setting depends on the Servopack type as shown below.
Servopack Type
DR2-j
DR2-jP
3) At full-closed loop specification, when Cn-01 bit 4 is set to 1, external PG phase-C dis-
connection error is not detected.
4) At full-closed loop specification, factory setting of Cn-02 bit B is 1.
For the Cn-01 and Cn-02 memory switches, always turn the power OFF and then ON after
changing the setting. This makes the new setting valid.
