Product details

What the 24 VDC Rail Tolerance Means

The 6SL3040-0MA00-0AA1: The 24 VDC input is specified with a tolerance band of 20.4 V to 28.8 V — that is a -15% / +20% window around nominal. In a mill environment where the control supply bus can sag during a main-drive acceleration event, this tolerance buys you ride-through down to 20.4 V before the CU320 drops its DRIVE-CLiQ communications. The 0.8 A draw (without DRIVE-CLiQ or digital outputs loaded) is the baseline; add 0.15 A per connected DRIVE-CLiQ node as a rule of thumb for sizing the 24 VDC power supply.

Frequently asked questions

How do I get current pricing and availability for 6SL3040-0MA00-0AA1?

Submit an RFQ through the distributor desk. This unit is sourced to order against a confirmed request — availability and current pricing are established at quote time. Given the mature lifecycle, expect a 3–5 week lead on a firm order if the part is not already in a distribution channel.

What is 6SL3040-0MA00-0AA1's listed voltage range?

The control unit accepts 24 VDC with a tolerance of 20.4 V to 28.8 V. It draws 0.8 A DC without DRIVE-CLiQ or digital outputs loaded, and dissipates 20 W under that condition.

Will 6SL3040-0MA00-0AA1 drop into a panel specified for a LOGO! or S7-300 CPU?

No — this is a SINAMICS S120 drive control unit, not a PLC. The 6ED1053-1FB00-0BA1 (LOGO! 230RCL) and 6ES7314-1AE03-0AB0 (S7-300 CPU) serve entirely different functions: the CU320 coordinates multi-axis drives over DRIVE-CLiQ, while the LOGO! and S7-300 handle logic and HMI. There is no direct panel swap without rewiring the entire control architecture.
