E-26 Technical Specifications
DC590+ Series DC Digital Drive
Terminal Information (Frames 6 & H)
These terminals are located externally on the product.
Terminal Description Terminal Function Terminal Number
Three phase supply Drive supply L1 - L3
Armature + Drive output to motor armature A+
Armature - Drive output to motor armature A-

External single phase ac Line 1 input to field bridge.
External single phase ac Line 2 input to field bridge.
Required AC Input Voltage = 1.11 x Nominal DC Output.
The field regulator will control the field current provided that the Nominal DC Output voltage exceeds the field
voltage by at least 10%.

FIELD
The external AC supply must be fitted with high speed fuses to protect the field regulator. For controllers with
10A field capability 10A fuses should be used, those with 20A field capability 20A fuses, etc.
Note: 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 transformer. L1
must be connected to FL1, and L2 to FL2.

DC supply for motor field connections.
DC supply for motor field connections.
The DC output voltage at these terminals will depend upon the AC supply voltage and the mode of field control.
Maximum drive field output capability is 60A DC.

External Armature Volts
Sense (+)
This connection can be used if a more accurate value of armature voltage is required, for example a DC line
reactor may be fitted. This terminal should be connected directly to the positive motor armature terminal.
MVA+
External Armature Volts
Sense (-)
This terminal should be connected directly to the negative motor armature terminal (see above). MVA-
