GPD515/G5 Drive
The GPD 515/G5 drive is a general-
purpose drive, intended for a broad
range of applications in Industrial
Automation. Accordingly, it is
available with many choices of I/O,
communications, and software. It is
available in constant torque ratings,
3/4 to 500 horsepower. The G5
HHP is available to 1500 HP.
G7 Benefits vs. G5
Enhanced G7 Performance
• Auto-tuning 3-Methods (R1/Static/Dynamic)
• World’s first commercial 3-Level Inverter architecture
(480V)
• Static no load auto-tuning offers same torque accuracy
performance as dynamic auto-tuning at base speed &
below
• DC input compatible (all models) simplified connection
to DC power, removal of internal DC bus choke not
required.
• Open-loop torque control
• Improved closed-loop speed response: 60Hz vs. 30Hz
• Improved open-loop speed response: 10Hz vs. 5Hz
• Improved open-loop speed range: 200:1 vs. 100:1
• Higher output frequency resolution: 0.001% vs. 0.01%
• Improved torque response: 300Hz vs. 150Hz
• Improved open loop starting torque: 0.3Hz vs. 0.5Hz
• Improved input voltage specification: 240 vs. 230 and
480 vs. 460.
New Keypad/Digital Operator
• Enhanced digital operator with copy function
• Simplified parameter menu navigation
• New LCD contrast adjustment
• Standard RJ-45 CAT-5 cable connection
New Functions
• New PID sleep function
• More preset speed selections: 17 vs. 9
• New automatic derating based on ambient temperature
setting
• New Bi-directional speed search with speed estimation
mode
G7 Drive
The G7 AC drive is the ultimate
performance solution with increased
speed and torque response to provide
servo-like performance from an i
motor. The 480V G7 drive has the
world’s first commercial 3-Level Inver
architecture for total system protection
This patented 3-Level architecture
eliminate peripheral components
typically required to solve installation
problems. G7 drive performance
the ideal drive for high performance
speed, torque, or position control
applications. The G7 is available in constant torque/heavy dut
ratings 0.5 to 500HP. The G7 is not intended for the simple,
routine AC drive application, it is for the challenges.
