# Actuator output

The Satellite menu allows you to connect to your devices and manage the actuators mode. It is located at the bottom of the Settings panel.

# The actuator selector

Hapticlabs Satellites are capable of driving any electromagnetic actuator. Typically, those actuators are classified as

Linear resonant actuator
Eccentric rotating mass
Voice Coil
Voice Coil actuator

Haptic actuators

Select the correct actuator type for each channel by clicking on the actuator symbol.

# The intensity range slider

Some actuators, especially large ERMs, require a higher starting voltage. In that case a very low intensity level eg. 1% can result in no actuation at all.

To adjust the intensity range of your actuator, click the corresponding panel, and pull the limits with your cursor or edit the numerical values for the intensity range slider on the bottom of the actuator selection menu.

# The frequency field (LRA only)

LRAs achieve maximum intensity if they are driven at their natural frequency. This natural (or resonance) frequency depends on the specific actuator hardware and can be found in the datasheet. You can enter its natural frequency in this field, any frequency values of blocks will be ignored.

# Frequency tracking (LRA only)

Depending on the application, your LRA might be in direct contact or mechanically coupled with different objects and materials. This can affect the resonance frequency of the resulting system. By activating the frequency tracking functionality, the Satellite will automatically determine the natural frequency of your device and will use it to drive the LRA.
