Minimum external braking resistor: 90 Ω
Continuous braking power: 230 W
Peak braking power: 6.25 kW
Control and Interfaces
Control supply: 24V DC ±20% (6A start, 2A continuous)
6 digital inputs (2 high-speed touch-probe), 3 digital outputs (50 mA)
2 analog inputs (±10V, 12-bit)
Resolver (X6) and high-resolution encoder (X7)
Motor brake output: 24V / 2A
USB, Ethernet, MMC card slot
Environmental
Ambient temperature: -10°C to +45°C (4 kHz), derating to 55°C
Protection: IP20
Pollution severity 2, overvoltage category III
Installation and EMC
Mount vertically with 100 mm clearance above/below. Use shielded motor cables (≤10 m). For cable lengths >0.3 m, shielded cables are mandatory. The integrated mains filter allows compliance with EN 61800-3 environment C2 (residential) and C3 (industrial). For hostile industrial networks, an external mains choke (4% uk) is recommended.
Commissioning
Connect 24V control supply first, then AC mains. Use DriveManager 5 via USB or Ethernet. The 7-segment display shows status (5=ready, 4=motor energized). Parameter sets can be stored to MMC card for cloning. The drive supports iPlc programming via CoDeSys (optional).
Applications
Ideal for servo motors up to 3 kW (400V). Typical applications include rotary tables, extruders, web handling, and pick-and-place machines. The peak current of 24A ensures high dynamic response.
Compliance
Complies with LVD, EMC directives and EN 61800-5-1. UL approval conditions apply (copper 75°C cables, 5kA rating).
The LTi SO84.012 delivers outstanding performance for demanding single-axis control tasks.
