Elevator Door Operator Inverter BG101-S20P2S/S20P4A – Nanjing Zhuye Elevatorparts
The elevator door operator inverter is the “brain” of the elevator door system, responsible for controlling the speed, torque, and smooth operation of the door operator motor, ensuring quiet, stable, and efficient opening and closing of elevator doors. The Elevator Door Operator Inverter BG101-S20P2S/S20P4A launched by Nanjing Zhuye Elevatorparts is a high-performance frequency conversion device tailored for mainstream elevator door systems, available in two power specifications (2.2kW for S20P2S and 4.0kW for S20P4A) to meet the needs of different elevator models. It is widely compatible with renowned brands such as Schindler, OTIS, and KONE, suitable for both passenger and freight elevators. Equipped with advanced vector control technology, built-in operation panels, and reliable protection functions, this inverter strictly complies with international elevator safety standards (EN 81-20, GB 7588) and has become a trusted choice for global elevator maintenance teams and manufacturers.
Nanjing Zhuye Elevatorparts adheres to the “quality first, safety-oriented” principle, implementing strict quality control throughout the production process of the BG101-S20P2S/S20P4A elevator door operator inverter. Each unit undergoes rigorous testing, including output frequency accuracy verification, load capacity testing, overheating protection assessment, and anti-interference performance inspection. The inverter adopts a high-integration circuit design and flame-retardant shell, effectively preventing dust and moisture intrusion with an IP rating of IP54. It is equipped with a self-contained operation panel for direct parameter modification and operation, supporting cycle switching of multiple menus (Fr, dr, n, P, d, U) via the “MODE” key. The built-in comprehensive protection functions include overcurrent, overvoltage, undervoltage, overheating, and motor overload protection, which can promptly cut off the circuit when an abnormality occurs to avoid equipment damage. The operating temperature range is -10℃ to 60℃, ensuring stable performance in harsh environments such as elevator shafts and machine rooms.
Usage Guide for Elevator Door Operator Inverter BG101-S20P2S/S20P4A
Correct installation, wiring, and parameter debugging of the BG101-S20P2S/S20P4A elevator door operator inverter are crucial to ensuring the normal operation of the elevator door system. Nanjing Zhuye Elevatorparts strongly recommends that only certified elevator maintenance technicians or electrical engineers perform related operations, as improper wiring or parameter setting may lead to inverter failure, door operation jamming, or even electrical safety hazards. Before operation, please carefully read the product manual provided by Nanjing Zhuye Elevatorparts.
1. Pre-Installation Preparation
First, confirm that the BG101-S20P2S/S20P4A inverter model (power specification) matches the elevator door operator motor parameters (voltage, power, rated current). Consult Nanjing Zhuye Elevatorparts’ technical team immediately if there is any uncertainty about compatibility. Then, cut off the elevator’s main power supply and door system power supply, lock the switch, and place a “Maintenance in Progress” warning sign at the elevator entrance and machine room door. Prepare professional tools including a screwdriver, wire stripper, crimping tool, multimeter, and anti-static gloves. Clean the inverter installation area (on the door operator or in the control cabinet) to remove dust, debris, and oil stains. If connecting to a large-capacity power transformer (above 500kVA), prepare a power factor correction reactor as required to protect the inverter.
2. Installation, Wiring & Debugging
Install the BG101-S20P2S/S20P4A inverter on the dedicated bracket and fix it firmly with screws (comply with Nanjing Zhuye’s torque specifications). Perform wiring strictly according to the wiring diagram: Connect the main circuit terminals (L, N for input; U, V, W for output) to the power supply and door operator motor, ensuring correct polarity and firm connections. Connect the control circuit terminals (for door opening/closing signals, door position signals, light curtain signals) to the elevator controller, and connect the encoder signals (if applicable) to the corresponding terminals (9 for 12V power, 10 for A-phase, 11 for B-phase, 12 for COM). Ensure all protective devices (overcurrent, short circuit, leakage protection) are correctly connected and the inverter is properly grounded. After wiring, restore the terminal cover before powering on. For debugging: Press the “MODE” key to enter the parameter menu, input the motor’s nameplate parameters (voltage, current, power, speed) first. Set P08 and P09 according to the control mode (encoder control or magnetic switch control); for encoder control, set P08=2 and P09=1; for magnetic switch control, set P08=2 and P09=4. Press “SET” to confirm parameters (note: P08, P09, P43 and other parameters require pressing “STOP” before modification). Activate the demo operation by pressing “▲+RUN” or “▼+RUN” to check if the door opens and closes smoothly. Adjust parameters in the U custom menu if the operation curve is uneven, then switch to normal mode to complete debugging.
3. Daily Maintenance & Inspection
According to the “Elevator Maintenance Rules” (TSG T5002-2017) and Nanjing Zhuye’s recommendations, the BG101-S20P2S/S20P4A inverter should be inspected monthly and undergo professional comprehensive testing annually. For daily maintenance: Power off before inspection, clean the inverter shell and heat sink with a dry cloth or vacuum cleaner to remove dust (avoid using water or chemical cleaners). Check the wiring terminals for looseness, oxidation, or burning, and re-tighten or clean them if necessary. Inspect the cooling fan for abnormal noise or stuck rotation, and replace it immediately if faulty. Check the operation panel for normal display and responsive buttons. Every 3 months, inspect the internal circuit board for dust accumulation (clean with compressed air if needed) and ensure the flame-retardant shell is intact. If the inverter displays fault codes (e.g., overcurrent, overheating), refer to the manual or contact Nanjing Zhuye’s after-sales team for troubleshooting.
Replacement Cycle of Elevator Door Operator Inverter BG101-S20P2S/S20P4A
The replacement cycle of the BG101-S20P2S/S20P4A elevator door operator inverter is determined by operating frequency, working environment, and component aging. Under normal conditions (elevator daily operation 12-24 hours, stable voltage, dry and clean environment), Nanjing Zhuye Elevatorparts recommends a replacement cycle of 5-7 years. This cycle is based on long-term field operation data and component reliability tests, fully considering the aging of internal electronic components, attenuation of cooling system performance, and degradation of frequency conversion control accuracy.
For elevators in high-traffic areas (e.g., large shopping malls, airports with door opening and closing ≥1000 times/day) or harsh environments (high humidity, heavy dust, frequent voltage fluctuations, or strong electromagnetic interference), the replacement cycle should be shortened to 3-5 years. High-frequency operation accelerates the wear of internal components and cooling fans, while harsh environments easily cause circuit board corrosion and signal interference. For low-usage elevators (e.g., villa elevators, small office buildings with daily operation time <8 hours) in stable environments, the cycle can be extended to 7-8 years, but annual professional testing by Nanjing Zhuye’s technicians is required to confirm that the inverter’s output performance, protection functions, and parameter stability meet safety standards.
Replace the BG101-S20P2S/S20P4A inverter immediately if any of the following issues occur, regardless of its service life: Frequent fault alarms (overcurrent, overheating, undervoltage) that cannot be resolved by maintenance; significant degradation of door operation performance (uneven speed, jitter, or slow response) even after parameter adjustment; severe damage to the inverter shell, water ingress, or circuit board burnout; failure to pass the annual professional safety test; internal components (e.g., cooling fan, capacitors) are severely aged or damaged, affecting normal operation. Timely replacement is critical to avoid door operation failure, which may cause passenger trapping or other safety hazards.
The Elevator Door Operator Inverter BG101-S20P2S/S20P4A from Nanjing Zhuye Elevatorparts integrates high reliability, high efficiency, and strong compatibility, providing a critical technical guarantee for the stable operation of elevator door systems.
