BD75E/230V Parker Positioning Servo Drive/Controller

The Parker / Digiplan BD-E Series is a series of high-performance brushless servo systems. These servo systems are CE marked and comply with the European EMC and Low-Voltage Directives.

The BD-E Series features the introduction of direct-on-line operation at 230V AC without the additional size, weight and cost of a separate transformer. All line filter components necessary for EMC compliance are built into the drive—this eliminates all potential problems associated with the mounting and wiring of external filter units.

BD-E Series drives have comprehensive built-in monitoring systems to protect both the drive and the motor. An I-t circuit limits the time for which any given motor current can flow before being clamped at the continuous rating of the drive. An additional monitor circuit guards against full drive current being delivered for an extended period at very low speeds. As well as protecting against supply overvoltage or undervoltage, partial supply failure, excess output current and overheating of the drive or motor, the BD-E also checks for overspeed conditions and loss of commutation or position feedback signals. With commutation data being derived from the incremental encoder, there is automatic tach fault protection since loss of the encoder signal will prevent commutation and therefore stop the motor.
