Product Description:
The ACS4815-500F motion unit from Kollmorgen's AC SuperDrive Motion Units series is a compact inverter-drive assembly for controlling three-phase induction motors in automated machinery. By regulating stator frequency and current, it allows speed, torque, and direction commands to be executed with closed-loop precision on the plant floor. Kollmorgen positions the ACS4815-500F as the interface between a low-voltage DC power bus and a squirrel-cage motor, supplying the modulation necessary for high-torque motion tasks in conveyors, packaging stations, and material-transfer axes.
The drive accepts a nominal bus voltage of 48 VDC, which is converted into a three-phase output whose stator frequency can be swept up to 250 Hz for wide speed ranges. Command and diagnostic traffic travel over CANopen, and the physical layer follows the ISO 11898 standard so it can share a trunk with other motion nodes. A watchdog window of 50 ms supervises incoming messages. If no valid frame arrives within that interval, the controller trips and forces the output stage into an inactive state after an additional 150 ms disable delay. These timing rules help prevent uncontrolled motion if the network cable is damaged. The internal control algorithms use the communication and safety intervals to maintain synchronized torque production under varying loads.
A finned aluminum heat sink removes switching losses. Its stack stands 116 mm tall and works with an airflow of 6 m/s to keep junction temperatures below the 85 °C heat-sink rollback threshold. Steady-state temperature rise is limited by a thermal resistance of 0.087 °C/W, allowing continuous operation without derating when cabinet ventilation is adequate. The housing carries an IP54 ingress rating, providing protection against dust deposits and water splashes encountered in most production areas. At 5.9 kg, the unit is light enough for panel mounting beside contactors, and an AMP SEAL 23-pin connector provides field wiring access for power, feedback, and brake circuits.
