Start Condition Error (VFC Hoist)

¿Qué significa 81 ?

Immediate switch-off, specific to 'VFC hoist' operating mode, occurring when the motor cannot be supplied with the correct current during pre-magnetizing time. This typically happens if the rated motor power is too small relative to the inverter, or if the motor cable cross-section is insufficient.

• Start condition for VFC Hoist application is not met.
• Hoist motor cannot start due to safety or operational interlocks.
• Incomplete setup of hoist application parameters.
• External signal preventing hoist motor start.

1. 1

   Check startup data and perform a new startup if necessary, ensuring the motor's rated power is compatible with the inverter's.

2. 2

   Check the connection between the inverter and the motor for any resistance or poor contact.

3. 3

   Check the cross-section of the motor cable and increase it if necessary to ensure adequate current delivery without excessive voltage drop.
