Position retained even without a battery
B&R compact servo motors are now available with an optional multi-turn encoder without battery backup. This allows the multi-turn position to be retained even if the connection between the drive and motor is interrupted. This option removes the need for a buffer battery in the servo drive. With this feature, these motors are perfectly suited for use with the ACOPOS P3 servo drive from B&R.
And with the new inductive digital EnDat 2.2 encoders (B8/B9), a wide variety of safety functions are also available. These encoders additionally guarantee a very high level of control accuracy and are resistant to disturbances. Motors in the 8LV series are available with a 40, 60 or 80 mm flange and cover a power range of 0.1 to 1.3 kW. Their compact dimensions make them the perfect choice for tight enclosures. These motors also have a direct gearbox mounting option.
The previous variants of the 8LV motor series are also still available. They are now even more compact and offer maximum performance with minimum space requirements. These variants also support the retention of the multi-turn position with a battery backup in the ACOPOSmicro servo drive.
Utilize braking energy effectively
The new 2-axis modules from B&R's ACOPOS P3 series feed braking energy back into the mains. This function significantly improves the overall effectiveness of a machine. With just 500 watts of regenerative braking power, the function pays for itself in only a year.
A prime candidate for this function are machine tools, whose headstock spindle drives generate large amounts of braking energy that would otherwise go unused. The function is also well suited for conveyor systems that move heavy loads vertically. Without power regeneration, not only would the braking energy go to waste, but the resulting heat would require additional cooling and consume even more power.
Regenerative braking is implemented particularly efficiently in the new 2-axis modules from the ACOPOS P3 series. One of the axes is configured as the feedback path to return excess power to the mains.
Save even more energy with ACOPOSmulti
Like the new ACOPOS P3, the active power supply modules from the ACOPOSmulti series also support regenerative braking. They also offer other helpful functions such as stabilization of the DC bus voltage independently of the mains voltage. Without any additional upstream transformers, this ensures consistent machine behavior – anywhere in the world.
