1.3.1
XRESOLVER
Correct wiring of the resolver is the
precondition
for good and reliable operation of the servo-
amplifiers series 2000 & 4000. Non-compliance of the instructions operations in this manual will
cause
a deterioration of the specified performances.
A cable with the following characteristics is needed:
3 pairs of conductors 0,14 mm2 twisted in pairs and shielded separately.
2 conductors of 0,5 mm2
an overall shield contacted with the previous shields.
The cable wiring should be done as Figure 2.
The overall shield must be connected to both the motor and the amplifier. It should be noted that
the contact from the overall shield to amplifier and motor must be made by using as much
contact area as possible. The use of "Pig Tail" on the overall shield should be avoided. It is
recommended to follow the convention (signal / conductor colour) used in this manual.
Contacts 2 and 6 are intended for the motor thermal switch wiring. The contact should be either
of type normally closed, or of type normally open.
It should have the following characteristics :
contact closed :
1 k ohm
contact opened :
10 k ohm
