Description

The WPG-A7-V4 Wireless Electronic Handwheel is a wireless manual pulse generator designed for CNC machine tool operation. It provides convenient wireless control of axis selection and pulse multiplication while allowing operators to move around the machine without being restricted by a wired handwheel. It supports up to 7-axis selection, 4 multiplier levels, and 100 PPR pulse output. The system operates on the 433 MHz ISM wireless band with a stated transmission distance of up to 45 meters under barrier-free conditions. Key Features Wireless 433 MHz communication Transmission distance up to 45 meters in barrier-free conditions Supports up to 7 axes: X, Y, Z, 4, 5, 6 and 7 4 pulse multiplier levels: ×1, ×10, ×100 and ×1000 100 PPR pulse output Emergency stop button Enable button for safe handwheel operation 3 programmable/custom function buttons on the V4 version Anti-interference design Sensitive operation with no obvious transmission delay Rechargeable lithium battery Standard USB Type-C charging port Supports 5–24V input power Pulse output voltage selectable from 5–24V Supports differential and single-ended signal output Compatible with multiple CNC control systems CNC System Compatibility The manufacturer lists compatibility with: Siemens Mitsubishi FANUC Fagor NUM Baoyuan SYNTEC Other compatible CNC systems Safety & Operation The handwheel uses an enable button as a safety feature. According to the datasheet, the enable button must be pressed to generate pulse output during operation. The shaft selector's O position puts the handwheel into dormant mode, while OFF shuts the handwheel down. Receiver & Pairing The product is normally paired at the factory, so re-pairing is generally not required. If the handwheel or receiver is replaced separately, pairing must be performed before use. The datasheet provides the pairing procedure and receiver configuration information. Receiver Output Modes The receiver supports different output coding modes: M1 – Point-to-point output mode M2 – Binary encoding mode M3 – Gray code mode M4 – Siemens dedicated code The corresponding axis and multiplier wiring charts are provided in the manufacturer documentation.
