3.2 Standard Connection Diagram
Connect the regenerative unit and peripheral devices as shown in
. It is possible to set and run the regenerative
unit via the digital operator without connecting digital I/O wiring. This section does not discuss regenerative unit
operation; Refer to
Start-Up Programming & Operation on page 67
for instructions on operating the regenerative unit.
Refer to
Drive Connection Example on page 77
for connection with a drive.
WARNING! Sudden Movement Hazard. Ensure start/stop and safety circuits are wired properly and in the correct state before
energizing the regenerative unit. Failure to comply could result in death or serious injury from moving equipment.
NOTICE: If unsuitable wiring is performed, the regenerative unit could be damaged. Implement protection for branches and
short-circuits according to all national and local standards.
NOTICE: Do not connect AC control circuit ground to regenerative unit enclosure. Improper grounding can cause control circuit
malfunction.
NOTICE: The minimum load for the relay outputs M1-M2, M3-M4, M5-M6 and MA-MB-MC is 10 mA.
NOTICE: When installing a noise filter on the regenerative unit power supply, use a reactor-type noise filter (without a capacitor), such
as a zero phase reactor, and install it after the MCCB on the power supply side. Do not install a filter with a built-in capacitor as the
harmonic components may cause the capacitor to overheat or may damage the capacitor.
NOTICE: When installing a breaker or contactor on the regenerative unit side for an emergency shutoff, confirm that the CHARGE
indicators on the drive and regenerative unit are not lit before closing the breaker or contactor on the regenerative unit output (DC) side.
If the power supply is turned on while there is a voltage charge, an overcurrent will flow and the device may be damaged. Always
confirm that the breaker or contactor on the regenerative unit output (DC) side is turned on before applying power to the regenerative
unit.
