Goodrive350-19 Series VFD for Crane Preface
Preface
Thank you for choosing Goodrive350-19 series variable-frequency drives (VFDs) for cranes.
If not otherwise specified in this manual, the VFD always indicates Goodrive350-19 series VFD,
which is a new generation of VFD that INVT develops for cranes by using advanced control
technologies based on more than ten-year accumulative hoisting-industry experience. The VFD
achieves excellent torque performance by integrating various special functions, including brake
control, zero servo, quick stop, master/slave control, switchover between three sets of motor
parameters, pre-magnetizing, light-load speed acceleration, anti-sway and sway reducing for
horizontal moving, tower crane slewing without using eddy current control, reverse braking, rope
detection, and travel limit, to ensure the safety, reliability, and high efficiency of the machinery. The
VFD can be widely used to drive the mechanisms such as about lifting, tilting, luffing, long traveling,
cross traveling, slewing, and grabbing in hoisting machinery.
In order to meet diversified customer demands, the VFD provides abundant expansion cards
including hoisting-oriented process card, PG card, communication card and I/O card to achieve
various functions as needed. Each VFD can be installed with three expansion cards at most.
The PG card supports a variety of common encoders including incremental encoders, resolver-type
encoders, sine-cosine encoders, and SSI absolute encoders. In addition, it also supports pulse
reference and frequency-division output. The PG card adopts digital filter technology to improve EMC
performance and to realize stable transmission of the encoder signal over a long distance. It is
equipped with the encoder disconnection detection function to contain the impact of system faults.
The VFD supports mainstream bus and control automation communication modes, including Modbus,
CANopen, PROFIBUS-DP, PROFINET, EtherNet IP, and EtherCAT, and thus can be seamlessly
interconnected with various crane control systems. You can connect the VFD to the Internet with
optional wireless communication cards so as to monitor it anywhere any time through mobile APP.
The VFD uses high power density design. The VFD models in some power ranges carry built-in DC
reactors and braking units to save installation space. Through overall EMC design, the VFD can
satisfy the low noise and low electromagnetic interference requirements to cope with challenging grid,
temperature, humidity and dust conditions, thus greatly improving product reliability.
This manual instructs you how to install, wire, set parameters for, diagnose and remove faults for, and
maintain the VFD, and also lists related precautions. Before installing the VFD, read through this
manual carefully to ensure the proper installation and running with the excellent performance and
powerful functions into full play.
If the product is ultimately used for military affairs or weapon manufacture, comply with the export
control regulations in the Foreign Trade Law of the People's Republic of China and complete related
formalities.
The manual is subject to change without prior notice.
