2.11.2.6 RESOLVER CONNECTOR (J5)
All the motor resolver cable and the PTC/NTC for the motor temperature control must be
connected to J5 connector located on the bottom side of the drive.
The mating resolver connector is a male Sub-D 9 pos., to be soldered, provided together
with the drive (Moog code AK5220). It is recommended to use low capacitance, multipolar
cable with 22 AWG (0,30 mm2) or 20 AWG (0,50 mm2) conductors, each pair twisted and
shielded, with an independent overall shield (with 85% min. coverage). Cable length
should not exceed 30 m. It is recommended that the cable and the power connection
cable be separated through the use of independent duct and by a distance of 30 cm. It is
also recommended not to make intermediate connections on the resolver cable.
With the resolver interface it is possible to use the simulated encoder outputs to J2C
connector. The standard pulse of the simulated encoder is 1024 (number of 64, 128, 256
or 512 is selectable via keypad). The standard width of the marker is 90° (width of 180° or
360° is selectable via keypad).
NOTE: DS2000 can be interface with resolvers with the following transformer ratios :
0.23, 0.26, 0.29, 0.47 e 0.50.
The two calibration resistors must have the correct value (the drive is pre-set in factory
in according to the motor, see the trasformation rating in the information sheet-Casella
report- of the drive).
In case of replacement/change of the application, verify the right calibration of DS2000.
If not please ask the Moog Service Center
