Multi-Motor Configuration

Running multiple Revolvers from one Stagehand.

It's not uncommon to try and run two (or more) motors from one Stagehand, especially for large or extremely heavy turntables. 
The Stagehand Apprentice is not able to operate multiple Revolvers though it can operate two 2hp motors!
What do you need?
Stagehand Pro or Stagehand Classic
Motor/Brake cable two-fer
Two (2) sets of motor/brake cables
One (1) set of signal cables
​Updated VFD Parameters​
Because we are running in a different Control Method (Pr.800) than normal, you do not need to autotune the VFD
Installation Process
​Install your Stagehand​
Use your Motor/Brake Two-fer into the Stagehand. 
​Install your Revolvers​
You only need ONE ENCODER. 
Choose one revolver to serve as the primary and install the encoder. The other encoder can be moved out of the way.
Run motor/brake cable(s) from each Revolver and plug them into the Motor/Brake Two-fer at the Stagehand. 
Run a signal cable from the primary Revolver and plug it directly into the Stagehand.
Changing VFD Parameters
Some of these parameters are available from the Spikmark Drive Communication menu, but a couple will need to be changed Using the VFD Keypad​.​
A800
A700
On the VFD Keypad: 
1.Press 
 until P.0 is displayed
2.Use the scroll wheel 
 to select each parameter to set
3.Press the 
 button and change the value with the wheel
4.Once you are set to the correct value, press 
 -- the display will flash between the parameter number and the new value.
5.Use the wheel 
to scroll to the next parameter 
6.Repeat the steps above and make sure all the parameters listed below are set to the correct value too.
7.Lastly, cycle power to your Stagehand
