Is an incremental or an absolute (EnDat) measuring system installed?
a) Incremental measuring system:
– Graduations
– Number of zero markers _ _ _ _ _ _
b) Absolute measuring system:
– Graduations
Determine the positive drive direction:
Where is the positive count direction of the measuring system? (see
Section 6.10.6)
––> invert the actual velocity value?
– Power section (connection with phase sequence UVW, CW rotating field)
– PE conductor connected?
– Shield attached?
– Various methods of temperature sensor evaluation
a) KTY84 evaluation via SIMODRIVE 611D only
b) Evaluation via SIMODRIVE 611D and external devices
c) Evaluation by external devices only
Note:
In case a) a temperature sensor coupling lead (dongle) must be con-
nected between –X411 and the measuring system.
(See also PJLM/CON/Connections:
Section "Encoder connection").
Check whether the measuring system cable is correctly attached to con-
nector X411 or to the adapter on the temperature sensor coupling lead.
