R911201352
The R911201352 (RD51.2-5B-005-L-A2-FW) high voltage drive control unit by Bosch Rexroth Indramat operates at peaks of 13A for 60 seconds at a pulse frequency of 4kHz and supports a 200% overload capacity for 0.5 seconds. Even when the connected motor is idle, it maintains active control and power terminals. The product should be utilized in its delivered condition without hardware alteration and cables or lines approved by the manufacturer.
This device operates optimally in ambient temperatures of 0°C to 40°C and requires 0.03m3/s of cooling air, thus mandating a cabinet with calculated ventilation. With a 22.5mm mechanical grid structure, multiple units can be installed adjacently within a cabinet. The model demands a minimum 100mm clearance overhead and below inside the cabinet for unobstructed air flow; the cooling air flows up from the bottom and hot air is expelled from the top. Despite being turned OFF, the unit can hold a high voltage up to five minutes due to the DC link capacitors. Its motor connection terminals are situated at the bottom, and the starting lockout mechanism is linked to the X80 connector.
