ACOPOSmicro provides drive modules for up to 2 axes for low-power applications. The ACOPOSmicro is designed to control both stepper motors and servo motors. • Extremely versatile • Integrated I/O • Compact design • Low power dissipation • Uniform design for inverter and stepper motor modules

1. ACOPOSmicro modules are equipped with safety function "Safe Torque Off" (STO) to ensure safe standstill and to avoid unexpected startup. Depending on the external wiring, safety classifications up to SIL 2 / PL d / Cat. 3 can be achieved. 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 per EN 1037 as well as the requirements concerning category 0 stop functions per EN 60204-1 are met. The requirements concerning the STO safety function per EN 61800-5-2 are also met.

2. Coding and marking The possibility of using keyed connection terminals is extremely useful, especially for the two-channel variant. In particular, this prevents serious errors that can occur by connecting the wrong drive axis during commissioning. Being able to easily label the ACOPOSmicro also helps to avoid errors.

3. Variable nominal voltage ranges To achieve higher torque values at high speeds, the first voltage variant was designed for a nominal voltage of 80 VDC. The ability to withstand overvoltage up to 95 VDC also allows for increases in the DC bus voltage such as those that occur during braking procedures. But the drive can also be used for almost any application in the extra-low voltage range. This means that the ACOPOSmicro product family can be operated up to a voltage of 18 VDC.
