Power and current at switching frequency
The LXM05CD17M2: Nominal power is 1.2 kW at 4 kHz switching frequency — the rating that governs continuous motor load in a typical positioning application. At 8 kHz the continuous output current drops from 8 A to 7 A, and the transient RMS output (3 s) goes from 12 A to 11 A. The 8 kHz setting quiets the motor whine but costs about 12% of the continuous current headroom. Line current draw is 10.5 A at 240 V supply, 12.7 A at 200 V — the lower the input voltage, the higher the input current for the same output power. Input is single-phase 200-240 V, 50/60 Hz, with limits of 170-264 V and 47.5-63 Hz. Overvoltage category III, so it's designed for fixed-installation distribution panels.
Obsolete — sourcing through surplus channels
Marked obsolete by Schneider Electric. No official successor or pin-compatible replacement is recorded from the manufacturer. Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. The 1 kA maximum prospective line Isc sets the SCCR for the branch circuit — the upstream protective device must be coordinated to keep fault current below this level. Inrush current is 60 A, which matters for sizing the supply contactor and transformer.
I/O and fieldbus integration
Six logic discrete inputs and one analogue input are on board — enough for limit switches, home sensor, and a speed/torque reference without an expansion module. The Modbus port has no polarization impedances fitted; if the bus is longer than a few meters, external bias resistors are needed at the master end. Maximum leakage current is 30 mA — a consideration when the drive shares a residual-current device (RCD) with other equipment; a Type B or selective RCD may be required to avoid nuisance trips.
Altitude derating and EMC fit
Output voltage derating applies above 1000 m up to 2000 m with conditions — for installations at altitude, the continuous output current must be reduced per the manufacturer's derating curve (not detailed here). The drive ships with an integrated EMC filter, which simplifies compliance to EN 61800-3 for the first environment (residential/light industrial) when installed per the manual's cable and grounding guidelines.
