7. The voltage model is only applicable to three-phase 380~480V power supply. If a single-phase 220V power supply is connected, the bus voltage under-voltage alarm will persist and the output capacity will be insufficient.

The compact body has a relatively small heat dissipation area. It is strictly prohibited to install it in a sealed cabinet. The upper and lower ventilation gaps must be ensured.

For high-frequency forward-reverse reciprocating loads, a large-power braking resistor must be externally connected to prevent the built-in braking power from overloading and damaging the device.

Parameter backup needs to match the corresponding DriveTop version. The FW firmware parameters cannot be directly imported into the FM firmware driver.
