External 24 Vdc supply
An external 24 Vdc supply is required to power all the low voltage circuits within the drive.
The cable length between the 24 Vdc power supply and the drive should not exceed 10 m.
The 0V connection of the external 24 Vdc power supply should be connected to the same ground connection as the drive. Where this is not possible
the 0V connection of the 24 Vdc power supply should be floating.
The working voltage range of the drive 24 V power circuit is as follows:
Table 4-1 Working voltage range of the 24 Vdc supply
Table 4-2 24 Vdc typical input current and power requirements
During start up of the external 24 Vdc supply, allow for an additional 1 A for 300 ms.
The drive will power down and reset if the external 24 Vdc is removed.
