Drive rating and duty selection
The MX2A4110E from Omron's MX2 series is a compact VFD rated for 11 kW under heavy-duty (HD) profile and 15 kW under normal-duty (ND) profile. That dual rating lets you size the drive to the motor load's duty cycle — use the HD number for constant-torque applications like conveyors or extruders, the ND number for variable-torque loads such as pumps and fans.
