Chapter 3 Front panel operation
40
2500 lines encoder: the range is 0~9999 (decimal system). It is 0 when Z pulse appears.
Absolute encoder: the range is 0 ～ 1FFFF (hexadecimal system), which indicates by high or
low position.
Resolver encoder: the range is 0~65535 (decimal system). It is 0 when Z pulse appears.
10. Control mode [note10]
The first three characters show the control mode, the final character shows gain group.
11. Alarm code [note11]
The " Err " followed by two minus symbols indicates no alarm and by digital number
indicates an error code number that is flickering. When alarm appears, the error code number
displays automatically on the front panel LED. During the error status, the monitor mode can be
changed to other mode by pressing buttons, but the decimal point of the last LED is still
flickering and shows existence of an alarm.
12. Multi-turn position of encoder [note12]
This display is only valid for absolute drive. Recording the multi-turn position of encoder
and coordinating with the single-ring absolute position of Apo rotor can work out the absolute
position of the rotor.
Absolute position = multi-turn position × absolute encoder bits + single-ring position
For example: multi-turn position shows 2000. Single-ring position shows 1000. Both of
them are hexadecimal.
Then the absolute position of encoder is (2000×2
17
+1000)
（

=40001000
Converting it as decimal number is 1073745920
When the absolute encoder is set as single-ring mode
（ P090=0), the multi-turn position
shows 0 and it will not alter as the change of rotor’s position.
