LS S100 and Veikong VFD500: standard-drive comparison
Compare LS S100 and VFD500 by HD/ND current, low-speed torque, STO, EMC, reactor, fieldbus, braking and maintenance access.
Short answer
What does this page recommend?
A technical alternative, not a drop-in substitute
VFD500 can be a technical candidate for S100 conveyor, pump, fan and general-machine duties. S100 SIL2 STO, C2/C3 EMC, integrated DC reactor or selected fieldbus features are not considered retained until verified on the exact VFD500 model.
Veikong
ProControl products to evaluate first
The exact configuration is selected after engineering review.
VFD530
Second candidate for projects needing IM/PMSM, PG feedback and machine logic; the safety function is engineered separately.

Similar requirement, different architecture
The table explains product architectures; it is not an exact order-code selection.
| Validation area | LS ELECTRIC S100 | Veikong / ProControl candidate |
|---|---|---|
| Current and duty class | The S100 product page publishes HD 150%/60 s and ND 120%/60 s; current selection depends on model. | The VFD500 HD/ND row at the same duration is compared with continuous output current and ambient derating; nominal kW is not used alone. |
| Low-speed torque | LS publishes 200% torque at 0.5 Hz for S100 sensorless-vector control. | VFD500 low-speed torque is verified by load test with the same motor and autotune conditions; percentages from different test methods are not equated. |
| STO | SIL2 STO information is published for S100; circuit, safety target and exact model also matter. | Where VFD500 STO is selected, its certificate and dual-channel behaviour are verified; otherwise external safe isolation is designed. |
| EMC and reactor | S100 publishes C2/C3 EMC and an integrated DC reactor on certain 400 V 30–75 kW models. | VFD500 filter and reactor hardware are selected for the exact frame; any component integrated in S100 is reintroduced in the panel BOM. |
| Fieldbus | S100 is offered with options including Modbus, PROFIBUS, EtherNet/IP and CANopen. | The required VFD500 card is selected from Modbus/CANopen/PROFINET/EtherCAT/TCP; PROFIBUS or EtherNet/IP requirements are treated as explicit gaps. |
| Maintenance and panel | S100 keypad, fan replacement and frame service approach establish plant practices. | VFD500 panel clearance, fan/filter service, parameter backup and spare replacement instruction are added to the new maintenance plan. |
Suitable scenario
When is it worth evaluating?
- Standard panel renewals for conveyors, pumps and fans
- General-machine projects using CANopen or Modbus
- Applications where reactor, EMC and safety components can be resized
Migration gate
Before making a decision
- Record S100 HD/ND current, motor load and cycle.
- Verify the STO SIL target and existing safety circuit.
- Enter integrated reactor, EMC filter and braking-chopper status into the BOM.
- Test required fieldbus protocol against VFD500 card/firmware suitability.
- Measure low-speed torque, motor temperature, stopping and fault recovery under load.
Frequently asked
Clear answers about alternatives and migration
Is this a drop-in replacement?
No. It is not a direct substitute until exact model, electrical, protocol-role, mechanical, software and certification checks pass.
What should I provide for selection?
The exact existing code, diagram or I/O list, PLC/network data, supply, environment and special functions in use.
Will VFD500 work on the same network where an S100 EtherNet/IP card is used?
The same network is not assumed until an official compatible EtherNet/IP option is confirmed for VFD500. If the protocol changes, PLC hardware and software are redesigned.

This content compares manufacturer-published data under the same project requirement; it does not guarantee direct substitution or project compatibility. ProControl engineering must validate exact model, revision, protocol, electrical, safety and environmental conditions.
