ATV58 TRX Type H Product Family
The ATV58 TRX series of adjustable
frequency AC drive controllers is a
Transparent Ready
TM
product line
providing extended functionality and an
extended horsepower range for the ATV58
AC drive family. The ATV58 TRX series
includes an analog output, expanded
firmware capabilities, and a horsepower
range up to 500 hp. As a Transparent
Ready product equipped with an Ethernet
communication card, the ATV58 TRX
product line can be configured, controlled,
monitored, and diagnosed over an Ethernet
network with a standard Web browser. No
special software or drivers are needed.
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.
