★ Automation Liberty is the authorized distributor for Kinco products. Competitor prices are indicative list prices from public sources and may vary. KC100 does not support STO PLd — use the KC200 if functional safety is required.
The KC100 is a general-purpose drive suitable for any application that does not require functional safety (STO). Below are the most common use cases.
Constant-Pressure Water Supply
Pair the KC100's built-in PID with a 4–20 mA pressure transducer. No external PLC required for simple single-pump systems. Supports multi-pump switching with a Kinco PLC.
HVAC Fan & Air Handling
VVC+ energy-saving mode reduces power consumption on variable-torque fan loads by up to 40% versus fixed-speed operation. Sleep/wake function for low-demand periods.
Conveyor & Material Handling
Multi-step speed control via digital inputs. Supports jogging, forward/reverse, and S-curve acceleration profiles. Typical pairing: KC100 + Kinco K615S PLC.
Woodworking & Machine Tools
Spindle speed control for routers, saws and lathes. Analog 0–10 V reference input accepts standard CNC speed command. FVC mode with encoder for closed-loop spindle.
Irrigation & Wastewater
Built-in sleep/wake and auto-restart after mains restoration. IP55 enclosure option for outdoor pump stations. Supports 4–20 mA flow or level transducer feedback.
Packaging & Food Processing
Precise speed control with 0.01 Hz resolution. Multi-speed presets for recipe-based production lines. Flying-start function for restart-in-motion scenarios.
Not sure if the KC100 fits your application?
Our engineers will review your motor nameplate and application requirements free of charge and confirm compatibility — typically within 4 hours.
Application Check →What the KC100 does not replace: If your G120 uses the PROFIBUS or PROFINET CUA31/CUM32 control module as the primary fieldbus, you'll need an optional communication card for the KC100. The KC100 also does not carry STO (Safe Torque Off) certification — use the KC200 if PLd functional safety is required. For straightforward I/O-controlled or Modbus applications, the KC100 is a drop-in equivalent at roughly 50% of the G120 list price.
V/F — Open-loop, simple speed control. Best for multi-motor applications or where load characteristics are constant and predictable.
SVC (Sensorless Vector Control) — Delivers 150% torque at 0.5 Hz without a speed encoder. Recommended for constant-torque loads: conveyors, compressors, mixers.
FVC (Flux Vector Control) — Requires a quadrature encoder mounted on the motor shaft. Achieves ±0.02% speed accuracy. Used for precision winders, spindles, and extruders.
VVC+ (Voltage Vector Control) — Energy-saving mode for variable-torque loads: pumps, fans, blowers. Reduces DC-bus voltage during partial load for significant kWh savings.
