FAQ

What is the main difference between this SINAMICS DCM and the older SIMOREG 6RA70 series?

The SINAMICS DCM offers higher dynamic performance, increased computing power, and better integration into modern automation systems via PROFINET. It’s more compact and features standardized engineering with the STARTER or TIA Portal software.

What do the option codes G00 and G10 mean for this drive?

G00 indicates that the drive is supplied without a communication board in the designated slot. G10 means it is equipped with a Terminal Expansion Module (TME) which provides additional digital and analog I/O for more complex control tasks.

Is this a 2-quadrant or 4-quadrant drive, and what does that mean?

This is a 4-quadrant drive. This means it can control the motor’s speed and torque in both forward and reverse directions, as well as perform regenerative braking, feeding energy back to the supply grid when the motor is decelerating.
