Product details:

Each of the GV3000/SE drives have one of following NEMA ratings:
• NEMA 1: Vented. Contains a communication access door that allows access to the
communication port without removing the cover. Intended for general-purpose
indoor applications.
• NEMA 1A: Ventilated with fan and filter. Contains a communication access door that
allows access to the communication port without removing the cover. Intended for
general-purpose indoor applications.
• NEMA 4X/12: Not vented. Supplied with base and keypad gaskets. Intended for use
in indoor environments that require a water-tight/dust-tight enclosure. An enclosure
with this NEMA rating encompasses both ratings (4X and 12).
• NEMA 12: Intended for use in indoor environments that require a dust-tight/drip-tight
enclosure.
See table 2.1 for a listing of the drives and their individual NEMA ratings.

Drive regulation is performed by a microprocessor on the Regulator board. See
figures 2.9, 2.10, and 2.11. Drive operation is adjusted by the parameters entered
through the keypad. The Regulator board accepts power circuit feedback signals and
an external speed reference signal, as well as data from an encoder that is attached to
the motor when set up for FVC regulation. The Regulator board provides:
• PWM gating signals to the IGBT power devices
Based on the output of the control loop, the regulator sends PWM gating signals
through the Current Feedback board to isolated drivers on the Gate Driver board.
These drivers switch the Insulated Gate Bi-polar Transistors (IGBTs), producing a
PWM waveform that corresponds to the speed (FVC regulation) or frequency (V/Hz
regulation) reference. The IGBTs can be switched at either a 2, 4, or 8 kHz carrier frequency.
