Fig. 15 The Linear Motor Controller
Motor Connector–Use this port to connect the linear motor used with the SI-MT or SI-
MKB muscle testers. The motor is setup and calibrated to the Linear Motor Controller that
is shipped with it. The motor and controller have a maximum range of motion of ±3.5mm
from the center of travel.
Position In–This BNC interface provides for an external position command input. The
input rage is ±10VDC. The signal presented at the input will affect the length of motor
travel. The motor/controller combination are calibrated for travel of 1.0mm/2.0VDC.
For example, +7VDC translates to +3.5mm of travel from the center, and –7VDC equals
–3.5mm of travel from the center.
Position Out–This BNC output provides a signal proportional to the sensor feedback from
the motor. Connect this port to a data acquisition system to track the motor position over
time.
Power–This LED Indicates that the controller has power from the Signal Conditioning
Amplifi er System.
