# Stagehand Classic+

The Stagehand Classic+ is the venerable Stagehand AC (AKA: The Classic) with an updated Stagehand Control Card - and some new bits inside. Think of it like a brain transplant and a facelift.

The updated Stagehand Control Card is powered by an ARM Cortex M4 processor and a PMD (Performance Motion Devices) Magellan motion chip. It's the same card that's in the Stagehand Pro and Stagehand Apprentice motion controllers. The new architecture breaths new features, like split accel/decel, into The Classic!

## New Features <a href="#h.o3s85yaaoaop" id="h.o3s85yaaoaop"></a>

### Split Acceleration and Deceleration <a href="#h.44xmnclt1exk" id="h.44xmnclt1exk"></a>

Write more complex cues with different ramp up and ramp down times

### Large Graphical OLED Display <a href="#h.y9rdup5xtahz" id="h.y9rdup5xtahz"></a>

See more information at a glance rather than cycling through all the fault codes

### Spikemark Drive Communication <a href="#h.jt8lpem61g12" id="h.jt8lpem61g12"></a>

That's right, you can set parameters and auto-tune your Classic right from Spikemark!

### Limit Overrides

Instead of using a limit jumper, you get new momentary buttons to override the limits when needed. The limit override status displays on the Stagehand Display as well as in Spikemark!

### Control Circuit Protection

Since we haven't needed the battery backup since Spikemark 3, we replaced it with much needed fuse protection for the control and encoder circuits.

## Existing Features

The Classic+ still has the following:

* 12VDC encoder voltage
* FWD and REV limits
* The same connectors you have been using for decades

## Facelift

Let's take a look at what's different about the Classic+

## Parameters

With upgraded features comes updated Parameters. Check out the full list [here](/docs/stagehand/stagehand-parameters/classic+-parameters.md).

## Troubleshooting

The same basic troubleshooting you'll find here holds true with the Classic+, but we did make some changes, so there are a few additional steps to take before reaching out.

### Power

* The Green Power Indicator is not on
  * Check the power is connected and any breakers are turned on
  * Confirm (with a meter) you have 208VAC 3P
* The Stagehand Display isn't on but the Green Power Indicator is
  * Check the 24VDC control fuse

### Encoder

* Encoder counts are not changing on the Stagehand Display
  * Check the 12VDC encoder fuse
  * Check encoder cable connections

### Emergency Stop

* Emergency Stop is Displayed on the Stagehand Display
  * An e-stop is engaged or the Showstopper cable is not connected
  * Confirm the Showstopper Base is operating
* VFD Keypad is displaying "SA"
  * The E-stop is engaged - release the e-stop
    * engage the e-stop then release to clear the Safety Controller
