Drive setting
Servo drive
• MD3000 digit 0 (Pn000 digit 0) FUNCTION_SWITCH_BASIC (For each axis)
Meaning: Selection of rotation direction
Setting value: 0 --- CCW rotation to be treated as forward rotation.
(1 --- CW rotation to be treated as forward rotation.)
Note: To set up reverse connection, use CNC machine data.
• MD3002 digit 2 (Pn002 digit 2) FUNCTION_SWITCH_APPLIC2 (For each axis)
Meaning: Method for operating absolute encoder
Setting value: 0 --- Uses an absolute encoder as an absolute encoder.
1 --- Uses an absolute encoder as an incremental encoder.
• MD3205 (Pn205) Multi_TURN_LIMIT
Meaning: Multi-turn limit setting
Setting value: Multi-turn limit setting of absolute encoder
You need not change this parameter setting even if you want to detect
rotation axis absolute value in YS 840DI system. (Excluding absolute
value detection with a External encoder using MP scale. Refer to next
section 14.1.6 for a setting when MP scale is used.)
Standard setting value: 65535
When multi-turn limit value inconsistency happens
If alarm 204 (A. CC) "Multi-turn limit value inconsistency" happens as a result of this parameter set-
ting, release the alarm by using Digital operator as follows.
1. Connect the Digital operator to the Converter. Select a drive (dr1, dr2 ...: the drive number is a
value, 1 more than the rotary switch setting value of each drive) to check by using [Up] and [Down]
keys, and press [DATA ENTER] key.
2. Press [DSPL/SET] key to display "Fn ***", and then press [Up] key to display "Fn013". Press
[DATA ENTER] key to display "PGSEt".
3. Press [DSPL/SET] key to display "done". The encoder is set to a value of Pn205.
4. Alarm is released when the power is turned on again.
Since the 20-bit absolute encoder cannot be released with Fn013, set MD34220 to a multi-turn limit
value + 1.
