When using an absolute encoder:
In the case where an ABS encoder is used, the ABS encoder should be set-up before any option units are attached and before the trial operation is commenced. Section 5.7 in the users manual should be read and understood before an Absolute encoder is used for the first time.
Basic Servopack/Servomotor Check: Trial Operation Section 4.1 in users manual.
1) Direction- Verify the direction by energizing control power (L1C & LC2) only, then monitoring Un-000 (7.1.7 Monitor Mode - 'Actual Motor Speed' [RPM]) for positive and negative numbers as the axis is moved by hand.
2) Change direction reference if required: This is done by changing the value in Pn-000.0 between 0 and 1. Don't forget to cycle the power if a change is made.
3) JOG the servo system: Jog is initiated with Fn-002 (7.2.2 'JOG operation using Digital operator'.) Always remember that the default JOG Speed is 500RPM and is set at Pn-304. Main Power (L1, L2 and L3) should be ON in order to JOG.
When using Option units:
1) If an absolute encoder exists, set it up first (5.7 'Absolute Encoders').
2) Check the Servopack and Servomotor connections and do the trial test described above (4.1 'Two Step Trial Operation')
3) If all is well, power everything down. Then connect option unit and re-power.
4) Adjust additional user parameters added to the system related to the option unit's existence.
Resetting a SGDH (Sigma II) Servopack to factory default:
1) Fn-005 (7.2.9 'Initializing Parameter Settings')
2) Fn-006 (7.2.5 'Clearing Alarm Trace back Data') This step is not mandatory, but is suggested.
3) Fn-014 (7.2.13 'Clearing Option Unit Detection Alarm') If no option unit was used, this is not required.
