) The maximum torque that can be attained depends on the drive controller used.
3
) Rated according to EN60204-1 (1993), installation mode B2 and conversion factor for Bosch Rexroth cables at
40°C ambient temperature. When using other cables, larger cross-sections may be necessary.
For notes regarding the power and connection cables, see Chapter 8.

5
) The data refer to operation with liquid cooling using water as the cooling medium. For further notes regarding the
generation of the coolant inlet temperature, see Chapter 9.5 “Motor Cooling“.
