ATV58 TRX TYPE H DRIVE CONTROLLERS

Features

The ATV58 TRX Type H drives are used for controlling three-phase asynchronous motors ranging from:

•1 to 350 hp CT (1 to 500 hp VT), 400/460 Vac, three-phase input

•0.5 to 7.5 hp CT (0.5 to 30 hp VT), 208/230 Vac, single-phase input

•2 to 40 hp CT (2 to 50 hp VT), 208/230 Vac, three-phase input

The ATV58 TRX Type H drive controller uses the latest in AC drive technology. Power modules are used on the entire product family. The modules contain insulated gate bipolar transistors (IGBTs) to produce a pulse width modulated (PWM) output waveform to the motor. The power modules minimize part count and improve reliability.

The Type H drive controllers integrate third-generation sensorless flux vector control for three-phase asynchronous squirrel cage AC motors. This allows the drive controller to deliver needed torque with excellent dynamic response over a wide speed range.

ATV58 TRX Type H drive controllers are capable of:

•Producing transient torque of 200% (±10%) of nominal motor torque for 2 seconds

•Producing transient torque of 170% (±10%) of nominal motor torque for 60 seconds

•Producing 160% of rated motor torque at 0.6 Hz with encoder feedback, or at 1 Hz without tachometer or encoder feedback (open loop)

•Regulating rated motor speed within 1% without tachometer or encoder feedback, or within ±0.02% with an encoder feedback circuit (option card)

Each Type H drive controller has a selectable switching frequency that can be adjusted to match the application requirements. The switching frequency can be programmed to fold back in the event of excessive heat. The drive controller reverts back to the programmed choice upon reaching the normal thermal state.

In addition, each 15 hp (CT) to 50 hp (VT) 208/230 Vac Type H controller and each 25 hp (CT) to 100 hp (VT) 400/460 Vac Type H controller includes a line reactor integrated into the heatsink plenum. The line reactor improves reliability and reduces input currents to the drive controller.

Most ATV58 TRX drive controllers are available with an integrated EMC filter. This filter reduces conducted and radiated emissions, and complies with IEC product standards IEC 61800-3 and EN 61800-3 for drive controllers.

Compliance with these standards meets the requirements of the European directive on EMC.

Configuration tools, operator interfaces, I/O extension options, and communication options are shared throughout the product range.
