: Indoor use only, below 1,000m altitude (derating required above this). Temperature should be between and with no dew. Mounting : Wall-mounted or floor cabinet types. Wiring Hazards : Do not connect input power to U, V, W output terminals.
The (often branded under Bosch Rexroth or Convo Electric ) is a compact, high-performance variable frequency drive (VFD) primarily used for single-phase to three-phase power conversion and motor speed control. This manual guide provides the essential technical specifications, wiring configurations, and programming steps needed for successful installation. 1. Key Technical Specifications
Maintain a minimum 100mm vertical clearance at both the top and bottom of the unit to support built-in fan exhausting.
To restore factory settings, look for the parameter initialization code (often under group 'b' or 'H' in similar Convo series).
0: Keypad digital setting; 1: Analog input (AI); 2: Multi-speed Acceleration Time 1
is a compact, multifunctional variable frequency drive (VFD) designed for controlling the speed and torque of three-phase AC induction motors. Often used in industrial machinery, fans, pumps, and conveyors, the is known for its reliability and ease of use.
To ensure reliable operation and long life, the CVF-S1 must be installed in a suitable environment. It should be mounted vertically on a non-flammable, vibration-free surface in a clean, dry location free from oil mist, metal dust, and corrosive gases. The operating temperature should be within the range of -10°C to +40°C . If multiple units are installed side-by-side, adequate spacing must be provided for proper airflow.
