Connection of forced cooling fan V

The AC motors in the DR.. series are also available with the forced cooling fan V. Using the forced cooling fan V extends the setting range of the setpoint speed. This means that speeds from 150 min^-1 (5 Hz) can be realized continuously.

INFORMATION

• For motors with V forced cooling fans, the P341 type of cooling parameter must be set to "forced air cooling".
• When using MOVIMOT^® drives with functional safety (STO), do not connect the forced cooling fan to the connection box. Instead, use an external DC 24 V supply to supply the forced cooling fan with power.

The following figure shows the cable routing of the forced cooling fan cable for MOVIMOT^® drives (without functional safety):
