Frequently Asked Questions

Why upgrade from 15kW to 22kW for my mega freight application?

The Drive-22KW-4 provides 45% more output current (48A vs 33A) and 52% more power capacity (32kVA vs 21kVA), enabling substantially heavier loads (3000kg+ vs 2000kg) and higher speeds (3.5m/s vs 3.0m/s). For industrial freight applications with 3000kg+ pallets or continuous heavy cycles, the 22kW ensures thermal stability and motor control precision under extreme stress. The 52A input current supports industrial electrical infrastructure with high inrush demands—critical for simultaneous multi-lift operations in logistics facilities.

Can the 22kW handle 4.0m/s ultra-high-speed with 2500kg load?

The 22kW with 48A output supports 3.5m/s operation with 3000kg or 4.0m/s with 2500kg in mega high-rise applications up to 100 floors. The 32kVA power capacity provides substantial headroom for the extreme power demands of simultaneous ultra-high-speed and heavy-load operation. For 4.0m/s+ or 3500kg+ applications, the 30kW (65A) or 37kW (78A) models provide necessary margins. Contact our engineers with your exact speed, load, and building specifications for optimal sizing.

Is the built-in brake sufficient for 3000kg descending from 100 floors?

For mega freight applications with 3000kg loads and 400m+ descent heights, the built-in 22kW brake handles substantial regenerative energy, but extreme duty cycles may require enhanced braking solutions. The 32kVA capacity provides power handling margin, but we recommend regenerative drive configuration or external braking resistor banks sized for your specific traffic analysis. Industrial freight with predominant downward heavy loads (ports, distribution centers) generates extreme regenerative power—our engineers calculate exact requirements from your height, load, speed, and cycle frequency.

How does dual CPU architecture handle extreme 3000kg load swings?

In mega freight applications with 3000kg unbalanced loads, the dual CPU architecture dedicates one processor to precise torque vectoring during extreme load starts, while the other manages safety circuits and door interlocks. This separation prevents control delays that could cause 3000kg load swing or imprecise stopping—critical for industrial safety. The anti-rollback function operates independently on the safety CPU, ensuring immediate brake application if anomalies occur during extreme lifting. The 48A output current provides the torque precision necessary for smooth 3000kg acceleration without mechanical stress.

What electrical infrastructure is required for 52A input current?

The 52A input current at 380V 3-phase requires robust industrial electrical infrastructure: minimum 63A circuit breaker, 25mm² supply cables, and dedicated transformer capacity accounting for inrush currents. For facilities with multiple 22kW+ elevators, we recommend centralized power distribution with power factor correction. The 32kVA power capacity may require 50kVA+ transformer allocation per drive for safe operation. Our engineers provide complete electrical specification sheets and can coordinate with your electrical contractor for installation planning.
