The positional data should be scaled in degrees relating to the output shaft:
1 rotation = 360°
S-0-0079 = 360; P-0-0079 = 400
The drive is to be operated on a 4mm spindle with a resolution of 1/100 mm:
1 rotation = 4 mm= 400 increments
S-0-0079 = 400; P-0-0079 = 400
The drive is to be operated on a 4mm spindle with a resolution of 1/10 mm:
1 rotation = 4 mm= 40 increments
S-0-0079 = 400; P-0-0079 = 40
The drive is to be operated on a 2mm spindle with a resolution of 1/100 mm:
1 rotation = 2 mm= 200 increments
S-0-0079 = 200; P-0-0079 = 200
The drive is to count 138.23 increments per rotation:
1 rotation = 138.23 increments
S-0-0079 = 320; P-0-0079 = 926
When you change the scale for the positional data, the actual value, the referencing value, the
positioning range, the upper and lower limits, the positioning window and the loop length are
recalculated.
3.6.3 Direction of rotation (S-0-0055)
The direction of rotation allows you to specify in which direction the drive should rotate during
runs to larger target values.
When looking at the output shaft, the following values are possible:
16: clockwise
23: counter clockwise
When you change the direction of rotation (S-0-0055), the referencing value (S-0-0175), the
positioning range (S-0-0278) and the upper and lower limits (S-0-0049 and S-0-0050) are set
to the delivery state.
3.6.4 Referencing (S-0-0175) and/or (S-0-0052)
Using the referencing value (S-0-0175) you can shift the whole range of values. There are two
ways of setting the referencing value:
Directly
– by writing the referencing value in S-0-0175.
Indirectly
– by writing a position value in S-0-0052. This allows any actual value to be assigned
to the current actual value. The resulting difference is then the referencing value (in S-0-0175).
A change to the referencing value automatically shifts the actual value, positioning range and
the upper and lower limits by the same value.
3.6.5 Setting parameters without automatic adjustment
If the user wants to avoid any automatic adjustment of values when setting the parameters for
the drive, the optimum order for sending the parameters is as follows:
Direction of rotation (S-0-0055)
Scale for the positional data (S-0-0079)
Extended scale for the positional data (P-0-0079)
Referencing value (S-0-0175) and/or referencing of the position (S-0-0052)
Positioning range (S-0-0278)
Upper limit (S-0-0049)
Lower limit (S-0-0050)
Positioning window (S-0-0057)
Loop length (S-0-0058)
In order to save the settings permanently in the EEPROM, you must then use S-0-0264 (see
Section 2.7.4).
