Standard Features
SmartCard
The SmartCard is a memory device that is supplied with every Unidrive SP and can be used to
• Parameter and program storage
• Simplify drive maintenance and commissioning
• Quick
• Machine upgrades can be stored on a SmartCard and sent to the customer for installation
Internal Dynamic Braking Resistors
During deceleration, the kinetic energy stored in the spinning mass of the motor/load combination is converted to electrical energy which recharges the drive’s DC bus. Dynamic braking resistors provide a means of rapidly dissipating that energy so that the drive does not fault from the DC bus over voltage trip. The Ohmic value and power rating of the braking resistor is a function of the drive type, size and duty cycle of the application.
