B.3.16.48 Regen Parameters
The Regen Parameters panel allows the user to see and set the regeneration parameters.
The regeneration control is implemented to prevent the capacitor over voltage caused by the energy that
returns back into the D.C. Bus during a rapid motor deceleration or an overhauling load.
To prevent it, a shunt regulator circuit senses when the bus voltage exceeds the Regeneration cut-in
voltage and switches a Regeneration resistor across the D.C. Bus, to dissipate the Regeneration energy.
REGENERATION PARAMETERS :
• Regen control mode → Allows user to select between:
o No Regen
o Duty-cycle
o Duty-cycle + fault
o Power fault only
o Power warning only
• Regen-On Voltage (V) → The regeneration transistor turn-on voltage.
• Regen-Off Voltage (V) → The regeneration transistor turn-off voltage.
• Regen Power (W) → The average regeneration power (measured).
• Max. Regen Current (A) → The maximum regeneration current.
• Regen Power Capability (W)→ The total regeneration power capability.
