3. ELECTRICAL INSTALLATION 11
WARNING
The drive HV supply input is not reverse polarity protected.
Reverse polarity connections will damage the drive.
Current and Capacitance
A supply must have a minimum amount of capacitance to support a drive at peak power
draw.
Drive Type DC Supply Current Supply Capacitance
ViX500 5.6A RMS
6600µF
ViX250 2.8A RMS
3300µF
Table 3-2. Drive Supply Currents
+24V Requirements
Both drive types require a +24V controller and logic supply. The supply may also be
required for an encoder and a Fieldbus Expansion Module (FEM).
Absolute voltage range 20 to 27V
Nominal drive current 250mA (excluding encoder, & FEM)
Encoder supply loading 150mA (if required)
FEM current 50mA
Safety Earth Requirements
Earth the drive using the earth pin on X1 (pin 8).
Power Supply Options
A set of torque curves (Figure 3-2) for various motor/drive combinations can be used for
calculating an applications likely power requirements.
Higher torque/current requirements will need to use the ViX500 drive and a high current
linear supply, such as the PL1100. Further power supply information is given in Appendix A.
