Multi-Motor Configuration

Running multiple Revolvers from one Stagehand.

It's not uncommon to need more muscle to spin especially large or heavy turntables. Believe it or not, multiple motors can be operated from a single Stagehand motion controller. As with all tricks, there are some limitations and considerations.

Limitations

To run multiple Revolvers from a single Stagehand you'll need a compatible Stagehand (Stagehand Pro or Stagehand Classic) and two of the same Revolvers (Revolver v1 & Revolver v2 OR two Revolver v3's).

The Stagehand Apprentice is not able to operate multiple Revolvers.

The Revolver v3 cannot be paired with a previous generation Revolver because the gear ratios are not the same

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

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

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. Press the button and change the value with the wheel
7. Repeat the steps above and make sure all the parameters listed below are set to the correct value too.

8. Lastly, cycle power to your Stagehand
