6.6.1 Checking the settings

Upon completion of the setup, check the system for proper function.
Danger!
Note:
Via actual value parameter
er value transmitted. Carry out a travel operation across a distance which can be
measured easily (e.g. 10 cm). Check if the actual value parameter
1267 changes and the
data
dance with your settings.
Via the scope function of VPlus, you can check the commissioning of the linear encod-
er.
Adjust the following scope sources:
1003 Act. Position * 1000
1007 Ref. Position * 1000
1013 Contouring Error *10 or 1012 Contouring Error *1
442 Hz: Act. Speed
As the time base, choose the observation period for some seconds.
When starting a motion block or a travel command via field bus, Ref. Position is set to
Act. Position. The two curves of sources 1003 and 1007 must be identical as from the
start time of the travel command. If the two curves are not identical, the parameter
factors have not been set correctly.
If the ramp Act. Position is steeper than the ramp of Ref. Position, the ratio 513/514
must be reduced.
If the ramp Act. Position is less steep than the ramp of Ref. Position, the ratio
513/514 must be increased.
Via the source of the contouring error, the quality of the settings can be checked addi-
tionally. The contouring error must not increase continuously. Due to the mechanical
characteristics, a small constant contouring error is typical to the system, continuous
(significant) increasing of the contouring error (also in negative direction) indicates
that linear encoder parameters have be set up incorrectly.
03/12
Wrong setup of the linear encoder can result in incorrect movements or
direction of movement.
The following requirements must be met when it comes to testing the
linear encoder:
• Before the start of the test, make sure the hardware limit switch-
es work properly.
• Before the start of the test, make sure the emergency stop works
properly.
• Use
slow speeds
o
slow ramps
o
Deactivate the position controller by setting 1118 = 0.
o
To reduce the speeds, you can use the so-called "Speed Override" mode.
