IMPULS -'G+&VG+ Adjustable Frequency Crane Controls MATERIAL HANDLING

Adjustable Frequency Crane Control Magnetek's new IMPULSE®»G+ and VG+ Series 4 drives continue our tradition of providing the most reliable and cost-effective adjustable frequency crane controls available. Industry-leading safety and performance features combine with our superior application expertise to provide unmatched performance for your material handling system.

SERies 4 Variable Frequency Drives Load Check II ™ continuously detects hoist overload conditions, halting upward motion and only allowing the load to be lowered. Load Check II continuously monitors the hook load, both during acceleration and constant speed, eliminating the need for load cells in most applications. It provides an auto-setup function which defines the hoist’s maximum hook load in seconds. With these control advancements, the drive no longer pauses for tests unless rated capacity is approached, providing increased productivity. provides a redundant hardware safety circuit...

Accessories Interface Card This provides a optically-isolated interface of 8 digital inputs (binary), 3 Form A dry contact digital outputs, 1 Form C dry contact fault output, 3 analog inputs, 2 analog outputs, pulse input and feedback, and RS-485 Modbus RTU interface. Input/Output Options Analog Inputs (13 Bit + Sign) – This provides interface of 3 high resolution analog inputs to the drive. Signal levels (individually selectable): 0 to +/- 10VDC (20kOhm) or 4 to 20mA (500 Ohm). Input resolution: Voltage (1/8192), Current (1/6654). AC Digital Inputs (4 Channels) – This provides a...

Control Options Network Communications Options Single Encoder—Line Driver This provides velocity and direction feedback from an encoder. This option is used for motor speed feedback in closed loop flux vector control. A 5VDC buffered output is also included. Signal levels: 5 or 12VDC differential line driver with compliments, maximum input frequency of 300kHz, phases A and B (Z required with some custom software). This allows for communication over 10/100Mbps Ethernet networks. This option has the ability to configure the IP address from a user specified IP address, from a DHCP host, or...
