UNI 3402 Drive Features

The right front display area of the UNI 3402 AC variable speed drive has an upper display that has two horizontal rows of 7 segment displays. The upper display shows the parameter value or the specific trip type. A lower display shows the status or current menu. The lower display shows the parameter number being viewed and has five directional programming keys. Beneath the directional programming keys are the Control keys. The Control keys consist of Forward / Reverse, Stop / Reset, and Run. A Large option module connection is under the control keys followed by the Small option connection. The bottom two items found on the front of the UNI 3402 are the Encoder connection beside the Control connectors. On the left bottom of the UNI 3402 drive are the AC In and the AC Out connections found under the protective cover.

In order to operate without derating, the maximum ambient temperature for the UNI 3402 is 40°C.

The UNI 3402 Ac variable speed drive requires a bookcase RFI filter with a max cable size of 10 mm² 6 AWG, with a weight of 3.8kg (9lb).

All UNIdrive models use a plug-in terminal block connection type, with a torque setting of 0.5 N m 4.4 lb.

The drive installation area should be cool, clean, and have ample ventilation as moisture and dust can damage the unit.

AC supply requirements for the Uni 342 include Voltage: Unidrive: 380V to 480V ±10%

Mounting the UNI 3402

The Unidrive may be surface mounted, or hole mounted.  When surface mounting, appropriate brackets must be used. A baffle plate is necessary when drives are through panel mounted. The baffle plate helps to ensure the correct level of airflow is maintained through the heatsink.
