Regarding the position setting in increments the rotation direction is adjusted by way
of the sign in parameter (Pd.8). A complete revolution is represented internally with a
resolution of 65536 increments. The 'high'- parameter (Pd.9) contains the increments
x 10.000, the 'low'-parameter (Pd.10) contains the increments x 1.
Please note that, when making the adjustment by way of the operator, the last digit as
of 32767 is not indicated in parameter Pd.9.
a) The drive shall run 13,75 revolutions clockwise
Pd.8 = 0 (+; forward)
13,75 • 65536 = 901.120 = 90 • 10.000 + 1120
Pd. 9 = 90
Pd. 10= 1120
b) The drive shall run 13,75 revolutions counter-clockwise
Pd.8 = 1 (-; reverse)
13,75 * 65536 = 901.120 = 90 * 10.000 + 1120
Pd. 9 = 90
Pd. 10= 1120
(also see Chapter 6.11.20)
The software limit switches determine the range in which positions can be approached.
If at the starting of the positioning the target position lies outside this range, then one
of the following errors is triggered:
• E.SLF (Error Software Limit Forward) Position outside the right software
limit switch
• E.SLr (Error Software Limit Reverse) Position outside the left software
limit switch
Depending on the selected position setting (revolutions or increments) different value
ranges apply.
Since the parameters are not locked against each other it is absolutely necessary to
ensure that with regard to the adjusted value the left software limit switch is located
to the left of the right software limit switch. Following parameters define the software
llimit switches:
• Left software limit switch

Pc.5 High
Pc.6 Low
