SIEI Drive by the Italian production of a high-performance drives, the first in the country by the West OTIS in matching synchronous motor has unique advantages: First, the drive features a rich PI, can be subdivided into paragraph 4 (including a zero speed PI), and width adjustable, so you can match toothless motor to the load when the signal to start the slide down to happen; Second, it has two sets of self-tuning procedure: a is the motor parameter self-tuning, it can automatically whole set of motor phase inductance and resistance constant, avoiding the motor manufacturers to provide motor parameters insufficiency caused by debugging difficult to improve; another is no tooth orientation tuning, the program is to test code and motor magnetic pole position corresponding.
SIEI Drive Features:
Automatic current regulator co-ordination, magnetic and speed controller, brushless motor magnetic automatic phasing.
Space vector modulation mode the noise level to a minimum.
2,4,8,12,16 kHz carrier frequency can choose between.
Output voltage up to 98% of the input voltage
Fault logger stores the 30 most recent fault alarm and the corresponding failure time
For the drive, motor and brake unit provides overload protection.
There are three standard devices freely configurable analog input port.
Via the optional expansion card (EXP D8R4, EXP D14A4F) scalable analog / digital outputs and analog / digital input
Adjustable speed and the torque current.
For many different types of feedback device (encoder) for management.
Speed adaptive function.
Speed-related alarms

Ordering the siei drive

To order the siei drive, send the exact model or reference code printed on the original part to [email protected]. Please quote the full code including any suffix so that our team can confirm the correct variant, current stock and lead time before you commit.

About the siei drive

Elevator and escalator installations are built around a relatively small number of serviceable assemblies, but they fail at very different rates. The siei drive sits in the control board / PCB group, and it is replaced on a different service interval from the assemblies around it. In practice the failures we see on siei drive come down to electrolytic capacitor ageing, cracked solder joints around the power stage, corroded edge connectors, and blown output transistors after a supply fault.

Every siei drive we supply is inspected before dispatch. Each unit is checked for physical damage, correct marking and the specific wear or degradation patterns that matter for this class of component, then packed to survive international transit. Where a superseded revision is the only one available, we say so plainly and explain the substitution, so the installing engineer can make an informed decision rather than discovering the difference on site.

Buying guidance and compatibility notes

Before ordering the siei drive, confirm three things. First, the controller catalogue number and the board revision letter, plus the fault code stored in the controller memory. Second, the same board is frequently fitted across several controller families, so the equipment model alone is not enough to identify the right revision. Third, whether the installation is a traction lift or an escalator, since duty cycle and loading differ between the two.

On fitting, one point is worth repeating: discharge the DC bus before removing a power board, and photograph the connector layout before you unplug anything. Almost every repeat failure we see on siei drive traces back to a related component that was left in place, or to an adjustment that was assumed rather than measured.

If you are unsure which variant of the siei drive you need, send a photograph of the nameplate and the existing component alongside a description of the fault. That is usually enough for our team to identify the correct replacement without a site visit, and it avoids the cost and delay of returning an incompatible part. We are also happy to advise on the other serviceable items in the same control board / PCB group, so a planned shutdown can cover several wear items at once.
