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".
• 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 converted 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 integrated 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.
