Safety information Product information Mechanical installation Electrical installation Multi axis system design Technical dataDigitax HD M75X Series Installation and Technical Guide 53Issue Number: 54.4 External 24 Vdc supplyAn external 24 Vdc supply is required to power all the low voltage requirements 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 possiblethe 0V connection of the 24 Vdc power supply should be floating.The working voltage range of the drive 24 V power circuit is as follow:Table 4-4 Working voltage range of the 24 Vdc supplyTable 4-5 24 Vdc typical input current and power requirementsDuring start up of the external 24 Vdc supply, allow for an additional 1 A for 300 ms.Figure 4-6 Location of external 24 Vdc supply terminalsThe 24 Vdc supply connector has been designed to allow wiring from either the left or right hand side of the drive. The same plug should be used butattention is required to the polarity of the wiring. If it is reversed, the drive will not power up but will not be damaged.For stand alone drives connection to either terminal is permissible.The drive will power down and reset if the external 24 Vdc is removed.All frame sizesNominal operating voltage 24.0 VdcMinimum continuous operating voltage 20.4 VMaximum continuous operating voltage 28.8 VMinimum start up voltage 20.4 VMaximum fuse rating 30 AModel / Option / Feature Frame size Typical input current (mA)@ 24 VTypical input power(W)Digitax HD M75X drive module 1, 2 894 21.53 1039 25SI-option module Per module 450 11High current brake output All 1200 28.8KI-Compact display All 10 0.24KI-Remote LCD keypad All 73 1.75WARNINGNOTENOTE
