The Opportunity to Save Costs in Any Space with i500 Series Frequency Inverters

No challenge is too great or single application too small. From industrial plants to OEMs to material handling and logistics centers, the Lenze i500 series of frequency inverters are hard at work. Versatile and robust, our industrial inverters are cost-effective and low maintenance. Whatever your specific conveyor application requires, Lenze has the inverter to match and exceed form, fit, and function. Use the chart below to help discover which inverter is right for your machine.

The Opportunity to Save

• Costs: Versatile sizing options for installation from decentralized to inside the cabinet.
• Time: Easy installation means less time spent on projects.
• Energy: Regenerative braking on the i550 motec means power sent back to the mains.

Lenze i500 Conveyor Solutions

Simplified Installation
i500 series drives are available in IP20, NEMA 1, as well as NEMA 4X versions, ready to mount where you need them. NEMA 4X models also feature an optional, lockable disconnect switch to service the motor right at the conveyor.

Integration
With a wide range of communication options, i500 series inverters are ready to integrate into your choice of upper-level controls vendor:

• CANopen
• EtherCAT
• EtherNet/IP
• IO-Link
• Modbus
• PROFIBUS
• PROFINET
• Modbus TCP/IP
• POWERLINK

i500 series inverters are compatible with both induction and PMAC motors, and have been employed successfully in Motorized Drum Roller (MDR) applications, keeping pace with design trends in the intralogistics industry.

Maximize Energy Efficiency

• Sizing: Conveyor motors are sized for the maximum torque starting condition; however, once a system is running at speed, the required torque and energy requirements drop significantly.
  • i500 series inverters are capable of 200% peak load for 3 seconds, and 150% for 1 minute.
• V/Hz Eco Function: To achieve maximum energy savings, i500 series inverters can dynamically adjust their V/Hz profile to reduce the voltage supplied to the motor as a function of dropping motor current.
• Regenerative Braking: Featured in the i550 motec is an integrated regenerative energy feedback mode. Benefits include:
  • Reduces energy consumption in dynamic braking
  • Transfers excess regenerative energy directly back onto mains
  • Simplifies engineering and system costs – no brake resistor required.

Precision Control

• Adjustable S ramp acceleration/deceleration allows jerk to be reduced, resulting in gentler material handling.
• Switch-off positioning can be employed for repeatable stopping orientation of the application.
• The NEMA 4X models can also be equipped with optional 22 mm operators which can be used for functions such as START/STOP and potentiometers for speed control, making operation easier for workers using gloves.

Safety
The i550 series also features an optional Safe Torque Off (STO) input module rated for SIL3 level e performance-ready to integrate into your plant’s stringent safety control systems.

Technical Details and Instructions

• V/Hz Eco Mode for Maximum Energy Savings
  Set the “Motor control mode” (P300.000) = “V/f control (open loop) [6]” and also set “V/f characteristic shape” (P302.000) = “Eco [3]” to take full advantage of energy savings for induction motors in conveyor applications.

• Minimize Jerk for Gentle Material Handling
  Set “Acceleration time 1 (P222.000)” and “Deceleration time 1 (P221.000)” as required for the application, then program a “Smoothing factor (P226.001)” to apply the S-Ramp to the profile.

• Switch-off Positioning
  Set “Stop method (P200.003)” to “Switch-off Positioning [3].” This method ensures the drive will delay deceleration to make the motor rotate the same number of revolutions as it would if the motor were commanded to stop from rated speed.
