Product Description:
The CR06551 CD Resolver is designed to provide precise position feedback with a rated continuous current of 6 A. For industrial automation systems that demand consistent and dependable electrical performance, the resolver from Kollmorgen is a must-have component. Mounting hardware is included and has a torque rating of 20 lb-in (2.26 N·m), and the unit has a weight of 4.92 lbs (2.22 kg).
The nominal voltage that the CR06551 resolver can handle is 230 VAC, and it has a tolerance of ±10%. It enables continuous current ratings of 10 A for three-phase and 7.8 A for single-phase operation. For 500 ms on single-phase and 23.4 A on three-phase, with lowered peak currents for two seconds each, peak current capacities are 30 A and 23.4 A, respectively. The resolver's control logic wire is 16/1.5 AWG (1.5 mm²), and the primary input wiring is 12/4 AWG (4 mm²), so the signals are intact and the power is transmitted efficiently. The motor screw torque is not specified, however the line screw has a torque rating of 12 lb-in (1.35 N·m) and a size of M3.5. In order to keep the correct installation spacing, the resolver needs 0.5 inches (12.7 mm) of space on either side.
The CR06551 CD resolver can function properly in surroundings devoid of dust or corrosive gases, as long as the temperature does not exceed 45°C (113°F) or 5°C (41°F). Mechanical and electrical stability are ensured by the mounting hardware and electrical connections. Because of its small size and low clearance requirements, the resolver is ideal for use in automated systems where every inch counts. With a continuous power rating of 0.7 kVA at 115 VAC line input, the resolver can reliably operate under rated loads.
Frequently Asked Questions about CR06551:
Q: It operates within ±10% voltage tolerance to maintain stable electrical performance under varying supply conditions.
A: Does CR06551 require specific line screw torque?
Q: Yes, the line screws require 12 lb-in torque to ensure proper electrical contact and prevent loosening.
A: How does the 0.5-inch side clearance benefit CR06551 installation?
Q: The clearance allows adequate spacing for heat dissipation and prevents interference with adjacent components.
A: Why is the continuous current rating different for 3-phase and 1-phase?
Q: The resolver supports 10 A continuous for 3-phase and 7.8 A for 1-phase due to differing thermal and electrical load capacities.
A: Does CR06551 support peak current for short durations?
