NOTE
These connections are not necessary for normal operation of the drive.
Supply an external 0V and +24V DC (
10%) control supply to this terminal to
configure and commission the drive without the 3-phase supply present. The drive
will not turn a motor. Each AC890PX can draw 2A, so for example: 3 units = 6A.
You can connect up to four AC890PX units using these terminals by daisy-chaining
the 24V supply (8A maximum). If you have more than four AC890PXs, wire each
drive individually from the 24V source.
Connection is not required when the 3-phase supply is present, but the connection
can be safely left connected.
The units are protected against reversal of this 24V DC supply.
1.
Apply the 24V DC.
2.
Check that all keypads are active.
Because the unit is powering up without the 3-phase connection, the keypad will
display "TRIPPED UNDERVOLTAGE", a trip indicating that the supply is
missing. Press the
ESC
key whenever this message appears.
If the unit is not powering-up with 24V DC: check your supply; check your
connections at X13; check the keypad is fitted correctly. If you are still
experiencing problems, please contact Parker Hannifin Manufacturing Ltd.
