15.1 Overview of Connections
The electric connections of Bosch Rexroth drives are standardized. The
MHD AC motors are provided with
• a power connector, incl. connection for temperature sensor and
holding brake,
• an encoder connection (feedback connector).
Both connectors are designed as separate plug connections.
