Product Description:

The 8V1320.00-2 is a three-phase servo inverter produced by B&R Automation for the 8V1 ACOPOS Servo Drives series. In multi-axis machinery, it converts AC mains power into a regulated output for controlling permanent-magnet motors. This output allows accurate velocity and position control in packaging, material-handling, and assembly equipment. The inverter can coordinate rapid motion changes while maintaining stable motor operation under varying mechanical loads.

For dynamic duty cycles, the unit can deliver a continuous phase current of 34 A rms, while short bursts of up to 80 A rms accommodate rapid acceleration without overloading the output stage. Its power section is rated at 16 kW and operates at a carrier frequency of 10 kHz, which helps keep current ripple low across an upper output frequency of 598 Hz. The DC link becomes active when the internal bus reaches 455 VDC. During startup, the inverter draws 13 A from the mains, while the supply sees an installed load of 30 kVA under steady operating conditions. A built-in brake chopper connects to an external braking resistor to dissipate regenerated energy during motor deceleration. The drive supports motor cables up to 25 m long without additional filters, preserving torque response across the permitted cable run.

The 24 V control rail has an input capacitance of 40,000 µF, providing stored energy for the inverter’s control electronics. The DC bus uses 1,645 µF of film capacitance to smooth voltage fluctuations caused by regenerated energy. When the brake chopper cannot immediately dissipate all excess power, this capacitance helps protect the power semiconductors and sustain the control logic. The auxiliary output can supply 0.5 A to connected field I/O, and an internal 12 A fuse disconnects the converter during an overcurrent fault. A minimum braking resistance of 15 Ω keeps the chopper transistor within its permitted thermal range. The enclosure has an IP20 protection rating for cabinet installation and weighs 10.6 kg, allowing secure mounting in an industrial control panel.

Error / diagnostic code What it means Corrective action
29207 Movement type not allowed PLC-open axis state (e.g., StandStill) blocks the requested motion Issue AxisStop, wait until the axis reports StandStill or Homing, then re-issue the command; verify state-machine sequencing in Automation Studio 
29216 Continuous movement not possible A prior axis fault forced the drive to abort a CV move Clear upstream errors, confirm the enable chain is stable, and re-trigger the motion block once Ready 
6021 Enable signal unstable +24 V “Drive Enable” input is sagging or chattering Tighten X1 terminals, load-test the 24 V supply, replace noisy relays or cables 
29203 Axis not ready to power-on STO inputs or other prerequisites are open (ReadyToPowerOn = FALSE) Close both STO channels, reset the safety relay / E-stop, then issue PowerOn again 
41075 Continuous power > 95 % Drive is operating near its thermal rating Reduce mechanical load or ambient temp, improve panel airflow, or step up to a higher-power frame 
9075 Load power > 100 % Over-load warning (drive still active) Check for binding, inertia mismatch, or aggressive accel/decel ramps; trend LOAD_POWER to confirm 
9076 Load power > 115 % Over-load trip; PWM disabled to protect IGBTs Same checks as 9075; allow heat-sink cool-down before reset; consider upsizing the drive 
6052 Power stage: high-side over-current A phase transistor detected an over-current spike Inspect motor leads for shorts, measure dV/dt, retune the current loop; fit a dv/dt choke if recurring 
6055 Holding-brake low voltage Drive cannot energise the motor brake to nominal level Measure brake-supply output, clean relay contacts, lengthen brake-release delay in parameters
6060 Limit speed exceeded Electrical output frequency > 598 Hz for > 0.5 s Lower the speed command or pole-pair setting, confirm feedback scaling, then re-test

29203 Axis not ready to power-on – STO chain or other prerequisites open 
6052 Power stage: high-side over-current – IGBT phase detected surge 
6048 Holding-brake movement monitor: position error too large 
6055 Holding-brake low voltage – brake coil cannot reach nominal level
