Industrial Drives FRENIC-GS Series

Reduces the number of devices and external cables by thoroughly streamlining the expansion of stack capacity and optimizing equipment configuration. Reduces installation costs and saves space

Minimizes installation costs by reducing external cables

Realizes space savings by optimizing the equipment configuration
(PWM converter to filter)

• Reduces the number of devices by using common filters when PWM converters are connected in parallel

• Reduces loss by eliminating filter resistance

Filter configuration when PWM converters are connected in parallel

Saves space through the industry’s highest level of compactness

Improved stack cooling structure provides the industry’s highest level of stack output.
Achieves the industry’s highest level of housing efficiency by adopting an optimized design and offering panel widths according to the number of housed stacks.

Expands stack output through an improved cooling structure

Contributes to improved quality and productivity using a high-speed
and high-precision E-SX bus

FRENIC-GS can be connected to the PLC (XCS-3000 Type E, SPH3000MG, SPH3000MM controllers) via the ultra high-speed E-SX bus. This bus makes it possible to support devices that require higher speeds and precision motion control. In addition, when used in combination with the XCS-3000 Type E controller, a network loop can be constructed, and if a disconnection should occur in one place, operation can continue.

Improved control performance expands the number of direct parallel connections

High-speed communication between CPUs increases the number of possible connections for inverters and PWM converters.

■Number of direct parallel connections

Up to six inverters and six PWM converters
note: Up to six inverters in parallel for multi-winding motors

note1: When using a direct parallel connection, current derating is required according to the number of connected units. Please contact us for details.

Inverter parallel connection systems

Achieves even more safe and reliable stoppages by improving the level of functional safety standards

The standard STO (Safe Torque Off) safety function has been improved to achieve more safe and reliable stoppages

Separates the information LAN from the control LAN to achieve both highspeed,
high-precision control and a large amount of data monitoring.
Promotes DX in production facilities and contributes to stabilizing production

Capable of transmitting a large amount of data (operation history, power, speed, torque, etc.) to PCs and analyzers over an information LAN regardless of the control LAN (control cycle), enabling long-term trend analysis and simulation.

Facilitates installation and operation by using industrystandardized panel dimensions

• Adopting standard panel dimensions makes it easy to replace the drive panels of other companies

• Reduced panel height improves visibility during maintenance and inspection

Reduced capacity operation allows continued operation even in the unlikely event of a breakdown

Example) If one inverter fails when 200 kW × 2 inverters
are driving a 355 kW motor, the operation can continue with the 200 kW inverter (capacity of one inverter).

If a stack fails in case of direct parallel connection, the Failure operation continues with lower output power using the stacks that have not failed.

note

To start the reduced capacity operation, consideration is needed to the switch over operation of PG signals or motor constants and sequence circuit.

note

Direct parallel connection is available for the same stack model.
