Report Frequency

Purpose

Notes

1

Motor RPM

once per minute (TBC)

Ensures agitator is running properly

2

Motor current

once per minute (TBC)

Ensures agitator is running properly
Higher motor current could indicate wear or snags

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.”
