Automated storage and guided vehicles

A single stacker crane in an AS/RS system typically has up to four axes of motion: Lift, extraction and two traverse drive wheels. All of this motion requires a lot of energy. Since the cranes are moving long distances at high speeds, power is typically delivered via a DC Bus supplied by our FR-CVL series of line regenerative common converters. These converters allow up to six Mitsubishi Electric inverters to be connected in a common DC Bus configuration and provide AC line regeneration.

AS/RS systems need to be able to move at maximum acceleration and velocity under varying load carrying situations. The MR-J4 amplifier contains advanced real-time auto-tuning technology that can automatically sense a change in load and alter the PID gains accordingly. This allows for maximum performance even with drastically changing load characteristics.

Being able to respond to changing customer demands is a key component of a successful material handling installation. In these flexible manufacturing environments, Automated Guided Vehicles (AGVs) become increasingly useful especially where conveyor systems are not practical. Therefore, AGVs must be completely stable even with changing external disturbances and have the ability to make quick and precise movements. Using the phase compensation function, all four wheels (or more) of an AGV can be perfectly synchronized.
