IMPORTANT The connection of the controller and the external field supply must be consistent when

using an externally supplied field regulator. Always derive the 1phase, 50/60Hz supply

from the L1 (Red) and L2 (Yellow) phases of the main power supply, directly or indirectly

through a single-phase transformer, with the Red phase connected to terminal FL1 and the

Yellow phase to terminal FL2.

IMPORTANT The auxiliary supply terminals must be connected directly to the incoming supply via a

fuse or circuit breaker. No series sequencing switches or contacts are permitted without

consultation from SSD Drives.

Use suitable external fuse protection: the steady state current absorbed by the controller is nominal, the external fuse

is determined chiefly by considering the contactor holding VA and the controller cooling fans. (Frame H fans are

powered separately).

The FIELD CONTROL function block controls the motor field. The FLD CTRL MODE parameter allows you to select either Voltage or Current

Control mode.

• In Voltage Control mode, the FLD. VOLTS RATIO parameter is used to scale the motor field output voltage as a percentage of the input supply

voltage.

• In Current Control mode, the SETPOINT parameter is used to set an absolute motor field output current, expressed as a percentage of the calibrated

field current (IF CAL).

Internal/External Supply (Frames 2, 3, 4 & 5)

NOTE The Frame 1 unit allows only an internal motor field supply. The Frame 6 and Frame H units always require an

external motor field supply. For information about the following terminal/power boards refer to Appendix E:

“Technical Specifications” - Terminal Information (Power Board).

The internal motor field is more widely used, however, there is provision on the unit for an external motor field supply to be connected (perhaps for

where the field voltage is greater than the input voltage and therefore not attainable, or where the motor field is switched separately for convenience).

External Motor Field Connections

Terminals FL1 and FL2 can be used for external ac supply connection for the Motor Field Supply. You should provide suitably rated external, fast-

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 FL1, and L2 connected to FL2.
