Bonfiglioli Vectron (AP) Series Servo Drive POWER BASE

The numbers 0031695 and E04 identify this as a specific Active Power (AP) Series Servo Drive module from Bonfiglioli Vectron.

Based on the coding “E04,” this is likely a Size 1 or 2 drive (the smallest in the range), typically rated for approximately 0.55 kW to 1.1 kW depending on the specific voltage class. The “180713” is the manufacturing date code (July 13, 2018).

1. Functional Overview

The E04 series is a compact, high-performance inverter/servo drive. It is designed to control either standard induction motors or high-dynamic brushless AC servomotors. It is frequently used in precision applications like:

• Automated packaging machinery.

• Conveyor positioning systems.

• Winding and tension control.

2. Physical Layout & Components

The unit is designed for “bookshelf” mounting (side-by-side) to minimize cabinet space.

• Top Terminals: Usually reserved for DC link connection and braking resistor connection.

• Bottom Terminals: Mains supply input ($L1, L2, L3$) and Motor output ($U, V, W$).

• Front Expansion Slots: The unit has two slots for modular expansion cards:

  • Slot 1 (Communication): For CM-CAN, CM-Profinet, or CM-EtherCAT cards.

  • Slot 2 (I/O & Feedback): For EM-RES (Resolver), EM-ENC (Encoder), or EM-IO (Additional I/O) modules.

3. Key Specifications (Typical for E04 Range)

4. Common Diagnostics (Status LED/Display)

If the drive is not running, look at the 7-segment display or the status LEDs:

• Ready (Green): The drive is powered and has no faults.

• Run (Green/Yellow): The drive is active and outputting current to the motor.

• Error (Red): A fault has occurred. Common codes for this model include:

  • F0101: Overcurrent (check motor wiring).

  • F0504: Motor Over-temperature (check thermistor connection).

  • F0700: DC Link Overvoltage (often caused by decelerating too fast without a braking resistor).
