Cooler connection for motors with integrated cooling
For built-in torque motors with integrated cooling, no alterations need to be made on the
machine construction for connecting the cooler.
You can directly connect the cooler via the fittings (1/8" pipe thread, DIN 2999). 1FW605 and
1FW606 motors are connected to the cooling system using plug connections that can be
simply released. For motors that are equipped with a precision and main cooler, each
cooling circuit can be separately fed and controlled.
Suitable connectors are required for connecting the hoses.
Note
Keep the pressure loss for motors with precision and main cooler low
Keep the pressure losses low by applying the following measures:
• Using a cooling connection adapter, connect the precision and main coolers in parallel
immediately before the cooler connections.
• Do not use excessively thin hoses directly after the cooling connection adapter.
The optional cooling connection adapter that can be ordered can be connected via a 1/4"
pipe thread (DIN 2999) either axially or radially on the outside.
Note
Cooling principle
In a series connection, the coolant must flow through the precision cooler first and then the
main cooler. Otherwise, the coolant already warmed up in the main cooler would enter the
precision cooler and have a negative impact on the cooling effect.
Every cooler has an inlet and discharge. As far as cooling is concerned, it doesn't make any
difference in which direction the coolant flows through the cooling circuit. Which connection
is used as inlet and which as discharge can be freely selected.
NOTICE
Destruction of the motor
Most of the motors have a permanently mounted cooling connection plate. If you remove
the cooling connection plate, the motor could be destroyed.
• Do not remove the cooling connection plate.
Note
It is only permissible to remove the locking plate for the cooling connection for 1FW605 and
1FW606 motors for service purposes, and this must be done by a Siemens service center
employee.
