5. Diagnosis and error treatment 5.1 General instructions on diagnosis Information on general diagnosis and fault treatment can be found in the manual for the SPC200 type P.BE−SPC200−... or in the WinPISA manual. This chapter contains special information on diagnosing the stepping motor indexer module. General diagnostic possibilities The SPC200 offers extensive and user−friendly possibilities of diagnosis and fault treatment.

5. Diagnosis and error treatment 5.3 Diagnosis with WinPISA In online mode WinPISA offers the following possibilities of diagnosing stepping motor axes: Status display Display of the inputs of the stepping motor indexer module Further notes and diagnostic possibilities can be found in the WinPISA manual or in the online help. Status display In order to display the status, select the command [Status display] in the menu [Online] [Diagnosis].
5. Diagnosis and error treatment Display inputs In order to display the status of the inputs, select the command [Stepping motor module] in the menu [Online] [Observe]. Fig. 5/2: Observe stepping motor module The inputs are shown by means of checkboxes as follows: Checkboxes Input Description Remedy End switch positive (Limit switch positive) LIM+ When the checkbox is deactivated, the positive limit switch (N.C.) is actuated.
5. Diagnosis and error treatment 5.4 Diagnosis on the control panel The control panel offers the following possibility of diagnos ing stepping motor axes: Display of the inputs of the stepping motor indexer module. Further notes and diagnostic possibilities can be found in the SPC200 manual. Display inputs 1. Select the command STEPMOTOR INPUT in the menu DISPLAY. 2. Then select the axis identifier of the stepping motor axis with v or V. Accept this with the Enter key. 3.
5. Diagnosis and error treatment 5.5 Emergency travel If a limit switch is actuated, the axis can be pushed manually into the positioning range again when the stepping motor controller is switched off. Alternatively, an axis can be moved into the positioning range again with the function Emergency travel." Caution Movement outside the limit switches may result in a collision. When the device is switched on, the axis must lie within the limit switches.
5. Diagnosis and error treatment Carry out emergency travel with WinPISA as follows: 1. Select the command [Stepping motor] in the menu [Online] [Commission]. 2. Select the axis identifier of the stepping motor axis in the dialogue window Commission stepping motor." If necessary, check the displayed status of the relevant inputs. Fig. 5/3: Commissioning the stepping motor 3. In order to carry out reference travel, select the option Emergency travel" under Activity." Start emergency travel with Start.
5. Diagnosis and error treatment Carry out emergency travel with the control panel as follows: 1. In order to carry out emergency travel, select the com mand AXIS in the menu TEST/DIAG. 2. Then select the axis identifier of the stepping motor axis with v or V. Accept this with the Enter key. 3. Now select the command EXIT FROM LIMIT with }. Start emergency travel with the Enter key. The current emergency travel can be interrupted with the Esc key or with the Enter key. 5−10 Festo P.
5. Diagnosis and error treatment 5.6 Notes on judging the positioning behaviour Resonance effects can lead with stepping motor axes to step losses and/or uncontrolled positioning behaviour. Deter mined by their principle 2−phase stepping motors are more susceptible to resonance effects than 3− or 5−phase stepping motors. The following table contains notes on judging the positioning behaviour as well as on the possible remedy.
