Decel Time (sec)

Load Type Normal Heavy

DC Bus Voltage

Vdc = Vac × 1.414 × 1.1

Peak Braking Power

P = kW × Torque%

Brake Resistance

R = V² / P

Resistor Power

Pavg = Ppeak × Duty

🧠 आसान भाषा में समझो

1. DC Bus Voltage:
AC supply को VFD पहले DC में convert करता है
Formula: Vdc = Vac × 1.414 × 1.1

2. Peak Braking Power:
Motor braking में energy generate होती है
Formula: P = Motor kW × Torque %

3. Braking Resistor:
Extra energy को heat में convert करता है
Formula: R = V² / P

4. Resistor Watt:
Continuous load कितना है
Formula: Pavg = Peak × Duty

⚠ Important Tips:
🔴 Resistance कम → Current ज्यादा → Drive damage
🔴 Duty ज्यादा → Cooling जरूरी
🔴 Heavy load → Bigger resistor
🔴 Fast stopping → High braking power
