1.1 How to Use This Manual
This manual provides technical information on IMPULSE
®
•G+ and VG+ Series 4 parameter settings, functions,
troubleshooting, and installation details. Use this manual to expand VFD functionality and to take advantage of
higher performance features. This manual is available for download on the Magnetek Material Handling document
center website at www.columbusmckinnon.com/magnetek.
The IMPULSE
®
•G+ and VG+ Series 4 VFDs share a common power section, and similar parameters. The
parameters and performance differ because the VG+ includes a PG-X3 encoder feedback card allowing the VFD to
perform Flux Vector control of the motor. The G+ VFDs operate in V/f or Open Loop Vector control methods,
appropriate for traverse or standard hoist motions. The VG+ VFDs are typically applied to the non-mechanical load
brake hoist motion, and can be applied to traverse motions where torque control or a wide speed control range is
required.
Many IMPULSE
®
•G+ and VG+ Series 4 parameter functions are common between the two VFD classes. The
functions that differ by model or control method are noted in the parameter descriptions. Table 1-1 below notes
which VFDs can operate in a particular control method.
Table 1-1: Control Methods by Model
The instructions in the following chapters apply to most IMPULSE
®
•G+ & VG+ Series 4 crane, hoist, and monorail
applications. However, carefully evaluate each specific situation and ensure that the National Electric Code (NEC)
codes and local wiring practices are followed.
These chapters explain how to install the IMPULSE
®
•G+ & VG+ Series 4 and, to some extent, the components that
it interconnects. It explains how to: assess the VFD’s environment, mount the VFD, and wire the VFD circuits. It is
important to develop a “plan of attack” for both the mounting and wiring since each task has an effect on the other
one. IMPULSE
®
•G+ & VG+ Series 4 Wiring Practices is included to provide assistance and reference.
NOTE: If the IMPULSE
®
•G+ & VG+ Series 4 is part of a Magnetek motor control panel, reference the
control drawings, disregard this chapter, and turn to Chapter 4.
