9.3.2 Option "F2", controlled Fan
To reduce noise emission the servo amplifiers can be ordered with the built-in option card
F2. This option cannot be built-in later. The F2 option card fits to slot2 or 3 (see part num-
ber scheme on p.24).
Function
The fan is switched on and off or runs with 50% rated speed depending on temperature
and brake power. That reduces the average noise emission.
Switching temperature
Monitoring Fan off Fan 50% Fan on
Internal temperature < 55°C ~ 58°C > 65°C
Heat sink temperature < 60°C ~ 65°C > 75°C
Brake resistor (internal) < 20W ~ 30W > 45W
9.3.3 Expansion cards "PosI/O" & "PosI/O-Monitor"
The “PosI/O” and "PosI/O-Monitor" expansion cards can be pushed into slot 2 or 3. The
expansion cards cannot be combined and the use of only one slot in time is allowed.
A detailed description of the interfaces can be found from page 142.
