Safety for compact stepper motors
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.
Stop function for Category 0
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.
New encoders for ACOPOSmicro
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.
