Frequently asked questions about STEP Electric
Q.What STEP Electric products and parts can Liftech Global Elevators & Escalators supply?
Liftech Global Elevators & Escalators can source, configure and commission STEP Electric as380 series serial controllers & integrated drives — including replacement boards, drive units, encoders and firmware — for new installations and modernization across Karachi, Lahore and Islamabad.
Q.Is Liftech Global Elevators & Escalators an authorized distributor of STEP Electric?
No. Liftech Global Elevators & Escalators is an independent multi-brand elevator engineering firm. We can work on, supply parts for and modernize STEP Electric equipment, but we do not claim to be an authorized distributor of the brand unless explicitly stated in a signed agreement.
Q.Where can I get STEP Electric elevator service in Pakistan?
Our head office in Karachi and regional offices in Lahore and Islamabad provide installation, modernization, spare-parts supply and AMC service for STEP Electric equipment nationwide. Call +92 300 0000000 or email info@elevatorescalators.com to request a technical consultation.
Q.Does STEP Electric equipment comply with EN 81-20/50 and PEC requirements?
STEP Electric systems are engineered to major international lift codes. Every commissioning or modernization performed by Liftech Global Elevators & Escalators is verified against EN 81-20 / EN 81-50 safety standards and Pakistan Engineering Council (PEC) regulatory requirements.
Q.How long does a STEP Electric modernization project take?
Typical single-car modernization on a STEP Electric platform — controller, drive, door operator and safety gear — is completed in 3 to 6 weeks after site survey and part arrival. Multi-car and high-rise programmes are phased to keep buildings operational.
Q.Which elevator controllers from STEP Electric are compatible with existing Otis, KONE, Schindler and Mitsubishi installations?
STEP Electric integrated elevator controllers (serial CANopen-Lift / DCP-04 architectures) can retrofit into legacy Otis, KONE, Schindler, TKE and Mitsubishi slings. Liftech Global Elevators & Escalators re-wires the traveling cable, re-parameterises the drive and re-certifies the safety chain to EN 81-20/50 before hand-over.
Q.Why specify an STEP Electric VVVF traction drive for PM synchronous gearless machines?
STEP Electric closed-loop VVVF drives deliver ±0.05 mm/s speed regulation with SinCos / EnDat encoder feedback, essential for smooth stopping accuracy under ±3 mm. This eliminates re-levelling, extends rope life and reduces motor heat losses on gearless PM machines by up to 30%.
Q.How is an STEP Electric gearless PM traction machine sized for a given elevator duty?
Liftech engineers select the STEP Electric PM machine using rated load, travel, speed, roping ratio (1:1 or 2:1) and starts-per-hour. The chosen machine's static/dynamic torque and duty-cycle (S3 40%–60%) must exceed the calculated demand with a safety margin, per EN 81-20 §5.9.
Q.When is an absolute rotary encoder from STEP Electric required instead of an incremental encoder?
Absolute EnDat / SinCos encoders from STEP Electric are mandatory on PM synchronous gearless machines because the drive needs rotor-position information from power-up — without homing. They are also required for UCM (Unintended Car Movement) protection under EN 81-20 §5.6.7.
Q.Where are STEP Electric door operators and landing components typically installed in modernization projects?
STEP Electric VVVF door operators mount on the car-top header and drive both car and landing panels through a coupler. Liftech Global Elevators & Escalators retrofits STEP Electric operators onto existing sills in Karachi, Lahore and Islamabad, tuning close/open profiles to EN 81-20 kinetic-energy limits (≤ 10 J).
Q.How do STEP Electric cabin fixtures, COP and LOP integrate with a serial car network?
STEP Electric COP/LOP panels communicate with the controller over CANopen-Lift or proprietary serial buses, reducing traveling-cable cores from 40+ down to 8. This lowers installation cost, improves diagnostics and enables features such as destination dispatch and remote fault reporting.
Q.Can STEP Electric components be supplied with EN 81-20 / EN 81-50 type-examination certificates?
Yes. Liftech Global Elevators & Escalators sources STEP Electric safety-critical components (controllers, overspeed governors, safety gears, buffers) with valid EU type-examination certificates and CE declarations, ensuring the modernized car remains compliant during PEC and third-party inspections.
