Smooth Motion
Vector control, S-curve ramps, torque boost, precise inching.
Safety Ready
STO input, brake logic, overload & thermal protection.
Smart Options
Encoder/PG card, anti-sway, synchronized long-travel.
Energy Handling
Dynamic-brake resistor or line-regen unit sizing guide.
Built for Heavy Duty Hoisting & Precise Positioning
- Hoist-grade control: fast torque response with brake interlock & motor thermistor.
- Travel efficiency: speed-sync for twin drives, creep speeds for alignment.
- Maintenance-friendly: fault logs, removable terminals, copy stick parameters.
- EMC & durability: chokes/filters, conformal coating options for harsh sites.
