Interfaces 8.3 Cooler connection

In the case a built-in torque motor with a cooling jacket, the coolant must be supplied/discharged via two holes (cut by the user) in the axes construction (see following diagrams). For information on the installation hole fit, refer to the section titled "Installation drawings/Dimension drawings".

To ensure optimized, uniform cooling across all cooling slots, the coolant infeed for torque motors 1FW609 and 1FW613 must be offset by 90° vis-à-vis the cable outlet for the electrical supply. If a different location is selected for the coolant inlet/outlet, the coolant is not distributed evenly in the cooling slots. The least favorable position for the coolant inlet/outlet is at an angle of 90° counter-clockwise because, in this case, the coolant can barely flow through the foremost or rearmost cooling slots.

The coolant infeed must be positioned directly above the exit point of the electrical cable outlets on 1FW615 torque motors.
