G.2.2: ServoTube Manual Phase
The CME 2 Manual Phase tool lets the user phase a brushless motor, monitor signals, check
configuration wiring, and control a microstepping current vector. The manual phase procedure is
followed by a manual phase troubleshooting procedure.
G.2.2.1 Make sure that no load is connected to the motor.
G.2.2.2 On the Main screen, choose ToolsManual Phase to open the
Manual Phase window.
G.2.2.3 Enable the amplifier by selecting.
G.2.2.4 To control the current vector rotation, use Rev or Fwd to command reverse or forward
motion.
NOTE: Some motors have bearings stiction, so helping the motor with mechanical
force is acceptable. Motors with no friction may need friction added to steady motion.
G.2.2.5 If the motor cannot keep up with the rate of vector rotation, then reduce the Increment
Rate or increase the Current.
G.2.2.6 Verify that pressing forward button moves motor forward. If it does not, toggle the
Motor Invert Output box setting.
G.2.2.7 Verify actual position count agrees with direction of rotation: increasing counts in
forward direction and decreasing counts in reverse direction. If it does not, toggle the
Encoder Invert Output box setting.
G.2.2.8 Monitor the vector rotation through one electrical cycle for proper Analog Hall rotation.
1 Verify that the red needle rotates in phase and in the same direction as the black
motor phase angle ±5 few degrees.
2 If the black needle and the red Analog Hall needles do not track in the same
direction properly, check the invert input analog Hall option swap the amplifier’s
analog Hall wire configuration.
3 If the red indicator transition leads or lags behind the centered needle by more than
5 degrees, then try adjusting the Hall Offset in +/- 30 degree increments:
