ATV58 TYPE FVC DRIVE CONTROLLERS
Features
The ATV58 Type FVC family of adjustable frequency AC drive controllers are
used for controlling three-phase asynchronous motors ranging from
1 to 75 hp (constant torque), 400/460 Vac, 3-phase input.
The ATV58 TRX operator interfaces, configuration tools, I/O extension
options, and communication options are shared throughout the product
range, except the general purpose option card which is not for use with the
ATV58 Type FVC controllers.
The ATV58 Type FVC drive controller uses the latest in AC drive technology.
Intelligent Power Modules (IPMs) are used on the entire product family. The
IPMs contain insulated gate bipolar transistors (IGBTs) to produce a pulse
width modulated (PWM) output waveform to the motor. IPMs minimize part
count and improve reliability.
The ATV58 Type FVC drive controller integrates fourth-generation
sensorless flux vector control for 3-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 Type FVC drive controllers are capable of:
• Producing transient torque of 200% (typical value ±10%) of nominal motor
torque for 2 seconds
• Producing transient torque of 170% (typical value ±10%) of nominal motor
torque for 60 seconds
• Producing 160% of rated motor torque at 0 Hz with encoder feedback
(closed loop) or at 0.5 Hz without tachometer or encoder feedback (open
loop)
• Regulating rated motor speed within 1% without tachometer or encoder
feedback or within ±0.01% with an encoder feedback circuit
Every Type FVC drive controller has selectable switching frequency that can
be adjusted to match the application needs. 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 25 hp to 75 hp 400/460 Vac drive controller includes a line
reactor integrated into the heatsink plenum. This line reactor improves
product reliability and reduces input currents to the drive controller.
Every ATV58 Type FVC drive controller is supplied 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.
