5.1 INPUT POWER SUPPLY
5.1.1 Three-phase Input Power Supply for Motor Power
See Subsection 5.1.1 “Three-phase Input Power Supply for Motor
Power” in Part I.
5.1.2 Single-phase Input Power Supply for Motor Power
See Subsection 5.1.2 “Single-phase Input Power Supply for Motor
Power" in Part I.
5.1.3 Control Power
Be sure to use a stabilized power supply as the 24-V power supply for
the βi SVM. The 24-V power supply for motor brakes cannot be
shared.
- Nominal rated voltage: 24VDC
- Allowable voltage fluctuation:
±10% (including momentary variations and ripples)
- Power supply rating: 0.9 A (per βi SVM unit)
5.1.3.1 Sequence for turning on control power supply
Turn on the control power supply of the βi SVM at the same time
when the power to the host controller connected via the I/O Link is
turned on or before the host controller is turned on. When turning
off the power to the host controller, be sure to also turn off the control
power supply of the βi SVM.
Host controller power supply On
Off
βi SVM control power supply On
Off
