Interfacing to a Motion Controller
In some applications, servo control is provided by a motion controller and the drive simply obeys a velocity
or torque command. The industry standard for this command signal is ±10V. In most cases, the encoder
signals from the motor must feed back to the controller. The SV7-S-AF servo drive includes a special Mo-
tion Controller Feedback board to accomodate such applications.
To connect an SV7-S-AF to a motion controller, you must make a cable to connect the motion controller
to the DB9 connector on the motion controller feedback board. Diagrams are shown below. Providing the
motion controller with access to the analog command, servo enable, alarm reset, and fault output signals
requires an additional cable to the SV7’s DB25 connector. See the diagram below for pin numbers. Note:
this diagram assumes that FAULT IN of the motion controller can accept a sinking signal.
You’ll also need to use our
QuickTuner™
software to set the drive for torque or velocity mode, to set the
scaling and offset of the analog input, and to configure the motor.
Encoder Outputs
If you are using the SV servo in torque or velocity mode with a servo controller, you may need to feed the
encoder signals back to the controller. The DB-9 connector on the motion controller feedback option board
includes encoder output signals for this purpose.
