J4: 24 VDC Logic Control
J4 is used to bring the 24VDC logic power into the Geo Direct PWM Drive. This power can remain on,
regardless of the main AC/DC bus power input, allowing the digital control electronics to be active while
the main motor power control is passive.
It is recommended to use a protected power supply. In situations where the power supply is shared with
other devices, it may be desirable to insert a filter before applying it to the Geo Direct PWM Drive.
If multiple drives are driven out of the same 24VDC power supply, it is recommended that each Geo
Direct PWM Drive be wired back to the power supply terminals independently. It is also recommended
that the power supply be sized to handle the instantaneous inrush current required to start up the DC-to-
DC converter action inside the Drive(s). See electrical specifications.
