The compact ACOPOSmicro Stepper drive is now available with Safe Torque Off (STO). Over time, this safety function will be added to all ACOPOSmicro drives.
B&R has integrated safe pulse disabling in ACOPOSmicro Stepper drives for shutting down safely and preventing unwanted startup. Safety ratings up to SIL2 / PLD / CAT 3 can be achieved depending on the wiring.
Safe pulse disabling interrupts the power being sent to the drive. Electrical torque can then no longer be generated, so the drive coasts to a stop. The requirements for preventing unexpected startup in accordance with EN 1037 as well as the requirements concerning Category 0 stop functions in accordance with EN 60204-1 are met. The requirements concerning the STO safety function in accordance with EN 61800-5-2 are also met.
- Safe Torque Off (STO)
- SIL 2 / PLd / CAT 3
- STO Enable input
B&R is further expanding the ACOPOSmicro servo drive series. In the future, SinCos and 5 V ABR encoders will also be supported.
Both 1-axis and 2-axis devices are available for SinCos encoders. The ABR interface has been integrated in a 2-axis ACOPOSmicro module. This device is equipped with two ABR 5 V differential inputs.
The technical data for the servo drives correspond to the data for existing ACOPOSmicro models. A rated current of 8 A, a trigger input, a motor holding brake connection and an enable input are available for each axis.
- Support for SinCos encoders
- Support for 5 V ABR encoders
- 8 A nominal current
