Does your application require a Regeneration Resistor? Refer to this Requirement Guide.

Application DescriptionIs a Regeneration Resistor required?
Traverse Motion (E.g., Bridge, Trolley, Monorail, Conveyor)YES. PE drives 5HP and under include a built-in resistor (Class D). For applications with motor sizes over 5HP, or applications that require a higher rating higher than Class D, a separate travel resistor bank is required. Use the tables on this page to select the appropriate travel resistor model number
Hoist/Lifting Motion (WITH Mechanical Load Brake, or a locking worm gear).In most applications, NO.*
Hoist/Lifting Motion (WITHOUT a mechanical load brake)YES. An appropriately-sized Hoist-Duty resistor bank is required. Use the tables on this page to select the appropriate hoist resistor model number.
*Some hoists with a mechanical load brake have some slip, even when adjusted to the manufacturer's specifications. In these cases, a small travel-sized resistor is appropriate for use with the hoist VFD.

Product Description

Regeneration Resistors are a necessity on all horizontal motion (bridge/trolley/monorail) applied Variable Speed drives.  Regeneration Resistors on PE® drives are not required on the majority of hoists with Weston type style INTERNAL load brakes – this is another unique feature of PE® drives on hoist applications.  Smart-Move® drives and the CX™ model size a2 and a2d (up to 5HP) have heavy-duty resistor banks built-in as one integrated drive solution.  For the larger systems, it is not feasible to place larger resistor wattage inside the electronic enclosure, so a separate resistor bank is required. Hoists without internal mechanical load brakes will utilize a PE® VECTOR SYSTEM specially designed for no-load-brake style HOIST DUTY and use. Refer to the table below for a summary of the applications when regeneration resistors are required.

Uniquely Designed for Crane Drives

Unlike all other drive types in the marketplace, the PE® VFD line has the unique feature of having the ELECTRONIC portion of the regeneration circuitry built-in and integrated into all standard drives, thus giving PE® drives the highest reliability in overhead crane/hoist applications.  Also, it makes for a very simple and quick installation of the drive with no expensive electronics (regeneration or dynamic braking options) required.  All that is needed in addition to the drive, are the specially designed “touch-safe” external PE® regeneration resistor banks.

It is NOT advisable to use “open-form” resistors on any variable speed drive.  The use of open-form “off the shelf” resistors are a hazard to life and property when used with variable speed equipment.  High DC Voltages are present, which have the capability of being life-threatening, even for a short period of time after the main power has been removed from a control panel.  Use PE® resistor banks for highest reliability and safety.
