Product Description:

B & R Automation 8V128M.00-2 8V1 ACOPOS Servo Drive is the advanced and unique drive for servo applications in demanding industrial production processes. One important characteristic of this servo drive is its no load current at rated voltage, which is equal to 4 mA. This low input current enables minimal power usage during operation and makes it suitable for use in automation systems. The drive is also suitable for heavy workloads in which low energy consumption is required which reduces the costs, including fuel, for ensuring longer-lasting equipment.

Another important characteristic of the 8V1 ACOPOS Servo Drive is the fast connectivity. The maximum switching delay is just 2.0 ms ensuring a very short response time of the drive for controlling motors. This quick switching delay is very important in applications where this drive needs to work at high speed and accuracy with complex machines. It shortens the time between giving a command and the drive carrying it out. These characteristics are perfect for fast and efficient movement control.

Another characteristic of the 8V1 ACOPOS Servo Drive is modulation compared to the ground potential which is ~38 maximum. This feature is particularly useful for reducing electrical noises and interferences in sensitive industrial settings. It controls voltage differences and reduces potential issues related to the drive performance. This feature contributes to the overall performance enhancement of the drive, reducing the chances of malfunctions caused by electromagnetic interference. These features make the B & R Automation 8V1 ACOPOS Servo Drive highly efficient and reliable in several industrial automation applications. The B & R Automation 8V1 ACOPOS Servo Drive is ideal for applications requiring high precision and fast control, such as robotics, CNC machines, packaging systems, and automotive production lines.

Error / diagnostic code	What it means	Corrective action
29207 – Movement type not allowed	Requested motion is illegal in the drive’s current PLC-open axis state	Issue AxisStop, wait until the axis reports StandStill, then re-issue the command or adjust state-machine sequencing
29216 – Continuous movement not possible	A previous axis fault forced the drive to abort a continuous move	Clear upstream faults, confirm the Enable chain is stable, then retrigger the motion block
6021 – Enable signal unstable	+24 V “Drive Enable” input is sagging or chattering	Reseat X1 terminals, verify 24 V supply under load, replace any intermittent relays or cables
29203 – Axis not ready to power-on	Safe-torque-off (STO) chain or other prerequisites not satisfied	Close both STO channels, reset the safety relay/E-stop, then issue PowerOn again
41075 – Continuous power > 95 %	Application load is running near the drive’s thermal limit	Reduce mechanical load or duty cycle, improve panel cooling, or up-size to a higher-power model
9075 – Load power > 100 %	Over-load warning (drive still active)	Investigate binding mechanics, inertia mismatch, or aggressive accel ramps; trend LOAD_POWER to confirm
9076 – Load power > 115 %	Over-load trip; PWM disabled to protect IGBTs	Same checks as 9075, plus allow heat-sink cool-down before resetting the fault
6052 – Power stage high-side over-current	A phase transistor detected an over-current event	Inspect motor leads for shorts, scope dV/dt, and retune current loop; fit a dv/dt choke if recurring
6048 – Holding-brake movement monitor: position error too large	Shaft moved while the holding brake was commanded closed	Check brake torque, verify brake delay parameters, and test the brake-wear limit
6060 – Limit speed exceeded	Electrical output frequency > 598 Hz for > 0.5 s	Lower speed command or pole-pair count, confirm feedback scaling, then re-test

Ordering Code

Error code	Meaning
29207	Movement type not allowed – axis state blocks the requested PLCopen command
29216	Continuous movement not possible – prior fault aborted a CV move
29203	Drive/axis not ready to power-on – STO or enable chain incomplete
6021	Enable signal unstable – 24 V “Drive Enable” too low / chattering
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 – coil cannot reach pull-in level
6060	Limit speed exceeded – output frequency > 598 Hz for > 0.5 s
9075	Load power > 100 % – continuous power overload warning
7210	DC-bus charging: voltage unstable – bus fails to reach/hold nominal
