Bonfiglioli SYN10S22007AF Synthesis Frequency Drive
The Bonfiglioli SYN10S22007AF Synthesis Frequency Drive is a compact inverter intended for compatible industrial motor control applications. It is identified by the model SYN10S22007AF, is rated at 7.5A, and is associated with a 220 to 240V supply range. The Synthesis series is used for local and panel mounted motor control where a compact drive with configurable parameters is required.
The current rating is the key selection value for this unit. The motor current, the supply, and the load profile should be checked against the 7.5A rating before installation. The drive should be integrated as part of a complete system with attention to the motor, the cables, the protection, and the cabinet environment.
Current Rating and Selection
The drive must be applied within its current rating. Selection should consider the motor full load current, the starting current, the load profile, the duty cycle, and the ambient temperature. If the application includes frequent starting or high overload, the system design should be reviewed.
The supply range of 220 to 240V should be confirmed against the site supply. The motor nameplate data should be entered accurately during commissioning so that the drive can regulate the motor within its intended limits.
Cabinet Installation
The drive should be mounted in a cabinet that provides mechanical support and environmental protection. The mounting surface should be stable and suitable for grounding. Airflow should not be blocked. Clearance around the drive should allow heat dissipation and access to terminals.
Labels should identify the drive and its main connections. The layout should allow safe measurement and maintenance. If the cabinet includes other heat producing devices, the thermal design should be reviewed.
Power Wiring and Protection
Power wiring should be performed by qualified personnel following the site electrical code. Supply, motor, and protective earth connections must be correct and secure. Cable sizes should be selected for the 7.5A class and for voltage drop. Motor cables should be shielded where required by the EMC plan.
Protective devices should be coordinated with the drive and motor. The user should confirm that short circuit and overload protection are suitable. Terminal screws should be tightened and checked before power is applied.
Control Wiring and Parameters
Control wiring should follow the connection diagram. Digital and analog signals should be routed away from power cables. Parameter setup should include motor data, frequency limits, acceleration and deceleration times, and input and output functions.
Parameters should be changed in a controlled manner and recorded. Default settings may not fit the application. The drive should be tested at low speed and light load before normal operation.
EMC and Grounding
Frequency drives can generate electrical noise. Good EMC practice includes separation of power and signal cables, proper shield termination, and low impedance grounding. Cabinet panels should be bonded where required.
If interference occurs, the user should inspect cable routing and grounding first. Sensors and communication lines are sensitive to noise.
Commissioning and Diagnostics
Commissioning should begin with a visual inspection and safety check. The motor should be tested at low speed and light load. The user should observe current, speed stability, and noise. Direction of rotation should be confirmed.
Diagnostics should consider supply quality, motor condition, load, wiring, and parameters. If the drive trips, the cause should be investigated before resetting. The event history can help identify the sequence of events.
Maintenance and Service
Routine maintenance should include checking cooling, terminals, and cabinet ventilation. The drive should be isolated and allowed to discharge before work. If the drive must be replaced, the replacement unit should be configured correctly and tested with the motor.
Application Value
The SYN10S22007AF supports adjustable speed control in compatible industrial machinery with a 7.5A rating for 220 to 240V systems. It can help match motor output to process demand and reduce mechanical stress during starting and stopping.
Summary
The Bonfiglioli SYN10S22007AF Synthesis Frequency Drive is intended for compatible industrial motor control. Correct current rating verification, cabinet installation, wiring, EMC practice, parameter configuration, and maintenance are essential for reliable operation.
