| 1 | Motor RPM | once per minute (TBC) | Ensures agitator is running properly | When the encoder is mounted on the motor, it rotates in the same direction as the motor. In the final design of the agitator, the encoder will be removed from the motor. It will be installed on a separate shaft that will rotate in the opposite direction of the motor. Noted here as the Galil-related software might need to address this internally. |
| 2 | Motor current | once per minute (TBC) |
| Suggestion from Galil (email to SG): “You can monitor the commanded current via the Tell Torque command (TT). This monitors the commanded torque or motor command signal that we are sending to the amplifier. This signal is a -10V to +10V signal. Using this with the amplifier gain (AG command) you can find what the command current is. For example, if TTA = 2V and AGA=1 (corresponding to 0.8A/V), the commanded current to the motor is 1.6A (TT*AG or 2*0.8). Please take a look at the TT and AG commands in the controller command reference for more details.” |
