Electrical Installation
Rotor position encoder - connection via a bl-tacho
only for DS xx-bl
3 rotor position encoder signals
(Hall sensors) for the
commutation; with or without a
brushless tacho.
The rotor position encoder is
galvanically connected with the
device zero (GND).
The voltage of 15V is supplied
by the servo-drive.
Provide an adapter in case the
tacho voltage at rated speed is
superior to 10V~.
For lower tacho voltages
connect X7: pin 1, 9, and 11.
Connect the tacho center point
to X7:1.
Use only motors with Rotor encoders (bl) which have been approved by UNITEK (Appendix
A). Observe the motor specific connection data sheet (bl)!
Connector
X7 15-pole D-connector
Connecting cable
12 signal conductors,
min. cross-section 0,25mm
Cable type
(4x(2x0.14)+(4x0.14)C+4x0.5)C
For link chains use appropriate cables!
Cable length
for >25m the cross-section of the cable used must be increased
by one grade
Shield connection
across connector X7-connect the shield to the connector housing
across the motor connector - connect the shield to the connector
housing
