Resolver connection
only for BAMOBIL-D3-RS
The resolver is an absolute measuring
system for a motor revolution.
It is robust and not impaired by high
motor temperatures.
Its build corresponds to
a revolving transformer.
The rotor is supplied by the reference
(10kHz).
The stator supplies the sine and
cosine signals modulated by the
rotational frequency.
The amplitudes of these signals are
analyzed and digitalized in the
servo-drive.
The resolution is automatically set to
an optimum of 10, 12, or 14 bit.
The max. possible speed is 50000
(10bit).
The digitalized signals are used for
the polar wheel angle,
the position and speed control, and
the incremental output.
Use only motors with a 2-, 4-, 6-, or 8-pole resolver
which have been approved by UNITEK (Appendix
A). Observe the motor specific connection data
sheet (RS)!
Connector X7
15-pole D-connector
Connecting cable
4 x 2 cores, twisted in pairs
and shielded, additional overall shield. For link chains use
appropriate cables!
Cable length
for >25m only use high-quality resolver cables with
adequate shielding properties.
Shield connection
across connector X7
combine all shields and
connect them to the housing
across the motor con.
connect the overall shield to the
connector housing
