The inverter ensures a smooth operation as well as having accurate levels at all times, within 5mm under all load conditions.
The drive / inverter calculates speed and torque based on the following hardware information:
- Load weighing device.
- Taco (close loop system).
- Internal amperage and voltage sensors.
The Drive / Inverter also has a built-in dynamic braking system that will prevent the elevator from over speeding when manually opening the mechanical brake (with or without power). The safety feature helps with ensuring safe rescue conditions.
