Parameter set loaded at the factory
The MOVIDRIVE
®
MCV 0E includes a special parameter set loaded at the factory and
a firmware optimized for special mechanical tolerances. The H variables H123-H127
have been assigned special functions for this optimization. They are initialized with the
following values (status 03/2009):
H variables
H123 = 1820
H124 = 32716
H125 = 10000
H126 = 125
H127 = 651
INFORMATION
SEW‑EURODRIVE does not give warranty nor assume liability for any malfunctions
of the system resulting from parameters differing from the default setting.
It is generally possible to reset the parameter set to the default setting via parameter
802 "Factory settings", or to change individual parameters.
The 5E special design is not delivered with uploaded parameter set, but with standard
factory setting.

Startup procedure
Parameterization
1. Make sure that the 0E or 5E servo controller is in controller inhibit or 24
‐
V opera-
tion mode.
2. Using the factory setting, perform a startup for a CM servomotor, for which the
continuous static current corresponds to the sum of the rated currents of all SLC
motors used in parallel on MOVIDRIVE
®
. The following must also be set for start-
up:
•
Temperature sensor is not connected (the TH sensor must be evaluated separ-
ately in a PLC)
•
Torque control operating mode
•
Current limitation P303 to the total maximum current of all SLC motors.
•
Stiffness, controller parameters and ramp times are not in effect in torque con-
trol operating mode.
3. Terminate motor startup with download.
4. Set the current controller index 8663 according to the formula
Index 8663 = L[mH] × nominal unit current × MDX factor
MDX factor:
•
= 0.02 for MDX = size 0
•
= 0.016 for MDX > size 0
