Product overview
ZB8610 18 Version: 1.5
2.5 Basic Function Principles and Commissioning
Area of application
The ZB8610 fan cartridge is delivered ready to operate. No adjustments need to be made to the device.
A typical application of the fan module is extension of the performance range of the terminals through forced
cooling. This enables the EL7201 EtherCAT servo terminal to operate with higher output current, for example
(4.5 A
RMS
instead of 2.8 A
RMS
), so that the performance is on a par with the EL7211, with the benefit of a 50 %
smaller footprint.
A further application is extension of the operating temperature range of the terminals. Depending on the
technical specification, the fan module enables the terminals to operate at temperatures of up to 70 °C. The
exact terminal-specific information for this application can be found in the documentation for the respective
terminals.
Commissioning
• Connect the ZB8610 fan cartridge according to the instructions in the section " LED display and
connection [
}
17] ".
• The fan can be operated in three different modes:
1. Demand-based control via an integrated temperature sensor (default, only power supply required)
◦ The fan cartridge starts operating at approx. 40 °C ( ̴2.700 U/min) and increases the speed
stepwise with increasing temperature
◦ From approx. 55 °C the fan reaches the full speed ( ̴5.500 U/min)
◦ If the temperature decreases below approx. 35 °C, the fan cartridge switches off
2. Continuous operation at full load (in addition to the power supply a high signal is applied at the mode
pin.)
3. Frequency controlled by an externally applied frequency (1 – 9 Hz) at the Mode pin, which is con-
verted internally in steps from 2,700 rpm to max. ~5,500 rpm. A digital output terminal, for example,
can be used as an external source. The measurement of the internal terminal temperature, which is in-
tegrated in TwinCAT, is used as reference for speed control of the fan via the frequency.
• In case of error there is a low signal on the "Diag" output and the LED display lights up red.
