When the drive configuration window is opened the Stagehand automatically reads in the following parameters from the drive.
PR.3 - Baseline Frequency
PR.9 - Rated Motor Current
PR.80 - Rated Motor Capacity
PR.81 - Number Of Motor Poles
PR.83 - Rated Motor Voltage
PR.84 - Rated Motor Frequency
PR.125 - Gain Frequency
PR.369 - Encoder PPR
PR.374 - Overspeed Detection
PR.800 - Control Method Selection
PR.C14 - Speed Gain Max
PR.414 - PLC Status
Then you can change these values by either using the Write Parameters button or by Auto Tuning.

Auto tuning is how the drive automatically measures motor constants to optimally drive a motor. This is an important step to insure smooth and reliable motion for a show.
You should perform the auto tuning process every time you use a different motor or cable length with paired with your Stagehand.
Auto tuning is required when running in Closed Loop Vector Control, and is recommended for Open Loop Vector Control. Previously this step had to be completed using the keypad on the front of the Stagehand. With the addition of the Modbus link in the Stagehand, auto tuning can be performed though Spikemark.
The steps are the same for both the Stagehand Apprentice and the Stagehand Pro, the only difference is more parameters are available on the Stagehand Pro.
Fill in the values(outlined above) in the Drive Configuration Window
Click the Red Auto-Tune Button
This will prompt the safety warning and once acknowledged will write the values supplied for the parameters to the VFD and begin the auto tune process.
The status of the auto tune is visible at the bottom of the auto tune window. While it is in progress it will say Auto Tuning and when it finishes it will say Finished Auto Tuning. If an error occurs the specific error will be displayed instead.
