Veichi CH310E Frequency Inverters for Elevators

Veichi CH310E frequency inverter for elevators

The elevator drive decides how a person feels inside the car. Too sharp a start is unsettling, a long crawl to the floor is annoying, and rollback at take-off is simply unacceptable. The Veichi CH310E series is a family of frequency inverters designed specifically for elevators — passenger and freight, in new buildings and in the modernization of older shafts.

What CH310E delivers

The drive works through the entire car travel profile — acceleration, cruising speed, floor-approach braking and precise stopping — so the passenger never feels the transitions between phases. Four independent S-curves and the ASR PI speed regulator handle this. At take-off the anti-rollback function keeps the car from drifting back under its load even without a weighing sensor, which matters most for gearless PMSM drives.

One drive for any elevator

CH310E works with both geared asynchronous motors (IM) and gearless synchronous motors (PMSM). A single series therefore covers both installing a new elevator and replacing an obsolete control station in an existing shaft. Power ratings run from 4 to 37 kW on a 3×380–480 V supply.

Safety built into the hardware

A braking module is built into every model — no separate unit to buy. The drive detects phase loss in under 200 ms, manages the mechanical brake and locks out start after a fault until the cause is cleared. On power loss it switches to evacuation mode from a 220 V UPS: the drive picks the lighter load side itself and brings the car to the nearest floor.

How to choose a model

The guide is simple — the elevator traction motor power and the drive output current (from 10 A on the smallest model to 75 A on the 37 kW unit). Low-rise and light passenger elevators are usually covered by the 4–7.5 kW range, multi-floor passenger and freight elevators by 11–22 kW, and heavy freight and high-rise applications by 30–37 kW. See the full range in the frequency inverter catalogue, the base platform in the Veichi AC310 series, and other brand solutions on the Veichi page.

Frequently Asked Questions

Will the CH310E fit my elevator?

Most likely yes, if your elevator has a drive in the 4–37 kW range with a 3×380–480 V supply. The series works with both geared asynchronous motors (IM) and gearless synchronous motors (PMSM), so it suits both a new elevator and the modernization of an old shaft. Send us the power and rated current of your elevator drive motor, its type (IM or PMSM) and the control scheme, and we will select the specific model.

What is needed for a gearless PMSM elevator drive?

For a gearless synchronous drive, the CH310E runs in a closed loop based on rotor position and immediately provides an anti-rollback start — the car does not drift at take-off even without a weighing sensor. This is a standard operating mode of the drive; no separate cards or add-on modules are required. You only need to connect the motor position sensor per the standard wiring.

Is an external braking resistor required?

The braking module is already built into every CH310E model, so there is no separate braking unit to buy. You only need an external braking resistor to dissipate energy while the car is decelerating. The 4 kW model uses a 130–170 Ohm resistor rated from 1100 W; for higher-power drives the resistor is chosen by load and start frequency. The drive monitors resistor operation.

How does the evacuation mode work during a power outage?

When mains power fails, the CH310E switches to a 220 V UPS supply and activates evacuation mode. The drive automatically detects which side of the system is lighter — the car or the counterweight — and moves the elevator toward the lower effort to gently bring the car to the nearest floor and open the doors. Passengers are not left trapped between floors even during a full building blackout.

How do I choose the CH310E power rating?

The series has nine models from 4 to 37 kW with output currents from 10 to 75 A. The main guide is the power and rated current of your elevator's traction motor: the drive is chosen to match the motor with a small current margin so it can handle starting loads. Light passenger elevators are usually covered by the 4–7.5 kW range, multi-floor passenger and freight elevators by 11–22 kW, and heavy freight and high-rise applications by 30–37 kW.

How does the CH310E differ from the general-purpose AC310?

The CH310E is built on the AC310 platform, but all the elevator logic is already implemented out of the box. That includes the anti-rollback start, mechanical brake and contactor control, UPS evacuation mode, four independent S-curves for comfortable acceleration and stopping, and phase-loss detection in under 200 ms. A general-purpose drive would need extra configuration and add-on hardware for these tasks, whereas the elevator version is ready to work in the shaft.
