Installing the Drive 3-21
DC590+ DRV Series DC Digital Drive
FRAME 3 : Power Board - PCB Reference AH385851
This power board can be altered for use with either an internal or external motor field supply:
Internal Motor Field (default for this board)
Terminals D3 and D4, the motor field outputs, are energised when the 3-phase supply to L1/L2/L3 is energised and the internal motor field is used.
Terminals D1 and D2 are not energised. The internal motor field supply is fused by the 10A fuses, FS2 & FS3.
External Motor Field Connections
Terminals D1 and D2 on the Power Board can be used for an external ac supply connection for the Motor Field Supply.
A simple re-wiring procedure disconnects the internal motor field supply and prepares terminals D1 and D2 for the external ac supply connection.
You should provide suitably rated external, fast-acting semi-conductor fusing, to a maximum of 10A.
Re-Wiring Procedure
WARNING
Isolate all power to the drive.
1. Loosen the control board fixing screws (2 off) and position the control board to allow
access to the power board.
2. Remove the red link/jumper from the Faston connector “F16” on the left-hand side of
the board and connect it to staging post “F19”, located below terminal D1.
3. Remove the yellow link/jumper wire from the Faston connector “F8” on the left-hand
side of the board and connect it to staging post “F18”, located below terminal D2.
Caution
When using an external ac input it is important to have the correct phase relationship on the terminals. The supply must be derived from L1 (Red) and
L2 (Yellow) phases directly or indirectly through a single phase transformer.
L1 must be connected to D1, and L2 connected to D2.
