Continuous and peak current — sizing the drive to the load
The ILM62DDD24B1000 is a detached triple servo drive rated for 2.7 A continuous under natural convection and 24 A peak. The continuous figure is the thermal limit for steady-state motor current in a fanless installation; the peak figure covers acceleration and deceleration transients. For a machine cycle where the RMS current stays below 2.7 A, this drive handles the peak without derating.
Supply voltage and DC-bus compatibility
Rated supply voltage is 250...700 V, covering 400 V and 480 V three-phase AC systems common in industrial mains. The wide range means the drive can be commissioned on a 400 V line with a 480 V backup generator without reconfiguration — the DC bus regulates internally.
STO safety function and machine guarding
Safe torque off (STO) is built in per IEC 61800-5-2 and ISO 13849-1. This removes the need for an external safety contactor on the motor power circuit for most guarding applications — the drive itself shuts off torque when the STO signal is removed. The standards listed (IEC 61800-5-2, IEC 61800-5-1, UL 618000-5-1, CSA C22.2 No 274, IEC 61800-3, ISO 13849-1, IEC 62061) cover functional safety, electrical safety, and EMC emission limits for the drive as a component.
Fanless cooling and IP65 — enclosure placement
Cooling is by natural convection — no fan, no filter to clog. The four mounting holes secure the drive; the fanless design requires free air movement around the heatsink fins for the 2.7 A continuous rating.
