10.9 Option "FAN", ventilator control
To reduce the average noise emission of servo amplifiers with fan, these amplifiers can
be ordered with built-in fan option card (ventilator control). This option uses (invisible from
the outside) the expansion slot.
The option FAN cannot be inserted later. Order the amplifier with built-in FAN
option.
Function
The fan is switched on and off depending on measured temperature values and brake
power. That reduces the average noise emission.
Switching temperature
Monitoring Fan off Fan on
Internal temperature < 55°C > 58°C
Heat sink temperature < 60°C > 65°C
Brake resistor (internal) < 20W > 30W
10.10 Option "EF", ventilator control and EtherCAT
In process.
These devices combine option "FAN" (see top of this page) and option "EtherCAT" (see
p.125).
The option EF cannot be inserted later. Order the amplifier with built-in EF option.
