Loading...What to do if the yellow LED is lit on my Lenze DC Drives?
If the yellow LED is lit, it could be because the brake resistor is not connected. Ensure the brake resistor is properly connected. Alternatively, the brake resistor might be dimensioned with a too high impedance. If permissible, use a low-resistance brake resistor, or connect several braking units in parallel.
What to do if Lenze 9350 controller sets pulse inhibit and reports overvoltage?
If the controller sets a pulse inhibit during braking and reports overvoltage, it could be because the braking unit is not connected to the terminals +U, ?U of the G G controller. Connect the braking unit to these terminals. Another possible cause is an incorrectly set switching threshold. Adapt switching thresholds of the braking unit and controller to the mains voltage.
How to fix a Lenze 9350 with an error if the green LED is not lit?
If the green LED is not lit, it indicates that there is no voltage at terminals +U, ?U G G. Switch on the mains. Otherwise, connect the braking unit to the terminals +U, ?U of the controller G G.
