Stepper Motor With Encoder And Toggle Switches. Steered Wheel With Mechanical Limitation: One Shot Installation Procedure - Zapi EPS-AC0 SWs&ENC User Manual

Step10 Verify the steered wheel rotates in the correct direction according to the
To get the system properly working it is necessary to set the encoder counting for a
whole steered wheel revolution together with the specification of the toggle switches
arrangement (one or two toggle switches and their succession inside a complete
steered wheel revolution). These setting are SET ENC AT 360 and AUX FUNCTION
11 respectively. When no mechanical limitation exists on the steered wheel, the
autoteaching function is the right mean for setting SET ENC AT 360 and AUX
FUNCTION 11 (see below).
Step11 Set special adjustment AUX FUNCTION 11 to level 0 or 1 if only one toggle
Step12 Set the special adjustment AUTOTECHING to ON and recycle the key (see
Step13 The steered wheel starts turning and a DATA ACQUISITION alarm appears
Step14 Set special adjustment DEBUG OUTPUT to 15 and recycle the key.
Step15 Read the WHEEL ANGLE in the tester menu and turn the steered wheel in
Step16 Now the position of the steered wheel, corresponding to a null WHEEL

Step18 Carry out the complete set-up procedure (see 10.1).
9.2 Stepper Motor with Encoder and Toggle Switches. Steered wheel
with mechanical limitation: one shot installation procedure
This procedure is relative to the connecting drawings Figure 5-3 It shall be applied
when the steered wheel may rotate less than a full revolution because of mechanical
limitations (i.e. with end strokes). It describes the step by step installation procedure

switch is adopted; set AUX FUNCTION to level 2 to 5 if two toggle switches
(0 degrees and 90 degrees) are adopted. A manual fine setting of AUX
FUNCTION 11 is possible too (see 10.3). If you consider it too complicated,
don't make it and go on with the present procedure.

in the hand set display. Two events may occurs:
1) After some revolutions the autoteaching procedure gets successfully
ended, the steered wheel finally stops and the DATA ACQUISITION
inscription in the display changes to the collected SET ENC AT 360 (left
side) and SET ENC AT 180 (right side) values. In this case, setting AUX
FUNCTION 11 is consistent (jump to Step 14).
2) The autoteaching procedure does not get successfully ended (steered
wheel continues to turn and never stops). In this case AUX FUNCTION 11
is inconsistent: if it is set to level 2 or 5 change it to level 3 or 4; if it is set to
level 3 or 4 change it to level 2 or 5. Then jump back to Step 12 for
performing a new autoteaching procedure.
the position with a null WHEEL ANGLE. Watch the steered wheel
orientation. If it is 180 degrees turned, change AUX FUNCTION in the
following mode:
1) if AUX FUNCTION is set to 0, turn it to 1 (or vice versa)
2) if AUX FUNCTION is set to 2, turn it to 5 (or vice versa)
3) if AUX FUNCTION is set to 3, turn it to 4 (or vice versa)
Then recycle the key.
