When are the heat sink fans of the 8200 vector switched on / off?
Answer:
If the frequency inverters' power is ≤ 11 kW, the fan is switched on with deactivation of the pulse inhibit (setpoint > 0 Hz) and is switched off 120 seconds after the pulse inhibit has been set.
If the frequency inverters' power is ≥ 15 kW the heat sink fan is switched on when the temperature is ≥ 50°C and switched off again when the temperature is ≤ 45°C.
