7-10 Power Connections
The inputs to the main (logic and motor supply) and the auxiliary
(logic supply only) power sources are separated. This permits the
logic power to operate independently of the motor. This dual power
sourcing is useful for troubleshooting and diagnostics.
Auxiliary Power
Auxiliary AC (Terminals 10 and 11) supplies power to the logic/
control circuits and fault logic. The main and auxiliary power must be
connected in phase.
AUX power is supplied to a switching power supply. This input
accepts Voltages from 100 to 240 VAC rms single phase with an input
frequency 47-63 Hz.
The auxiliary (logic supply only) and the main (logic and motor
supply) power sources are separated. This permits the logic power to
operate independently of the motor. This dual power sourcing is
useful for troubleshooting and diagnostics.

1. Dual element, time delay (slow acting) fuses are required to accommodate inrush
current at the auxiliary terminals during power-up. Local regulations must be
observed when selecting fuses.
2. The ULTRA 200 Series drives do not require an isolation transformer. The recom-
mended transformer sizes are the minimum that is adequate for most servo applica-
tions. Larger transformers provide an additional safety factor. The additional safety
factor may occur in applications that require minimum bus voltage sag when the
motor must accelerate to high speed in minimum time or in applications with high con-
tinuous power requirements.
