3-14 Basic Installation MN1902
3.4.7 External customer supplied 24V control supply
Depending on model (catalog numbers FDHxxxxx-xxx3 and FPHxxxxx -xxx3) a 24VDC
control supply must be provided to power the control electronics. This is useful for safety
reasons where AC power needs to be removed from the power stage but the control
electronics must remain powered to retain position and I/O information. It is recommended
that a separate fused 24V supply is provided for the FlexDrive
II
. If other devices are likely to
be powered from the same 24V supply then a filter (Baldor catalog number FI0014A00) should
be installed to isolate the FlexDrive
II
from the rest of the system.
