Appendix A – Specifications

Undervoltage Protection

The Gemini drive’s undervoltage protection circuit monitors AC input voltage. If
input voltage falls below 75VAC while the drive is operating, the drive issues an
undervoltage fault, and turns off power to the motor.

Undervoltage protection has the following features:

Threshold Voltage:

Voltage falling below 75VAC trips fault

Results of Fault:

Power to motor is turned OFF

LEDs: Left = illuminated RED; Right = off

Fault output is activated

Latched fault

Regeneration Protection

The Gemini drive’s regeneration circuit protects it from regenerated energy—
excess energy from the load during deceleration.

NOTE: Regeneration for an extended period of time can cause a regeneration
fault.
