The Rolling Inductor can be operated
with Manual Control, Temperature
Control only, or Temperature Control
with Travel Detection.
Manual Control provides Max Output
power, as set in SYSTEM SETUP1
screen, at the start of the cycle.
Temperature Control provides output
power starting at the RI Init KW value,
as set in SYSTEM SETUP1 screen, at
the start of the cycle. The curves
illustrated increase as shown directly
from the RI Init KW value.
The rate of power output is limited at
travel speeds below 15 in./min (38cm/
min) or when no travel detection is
present to help prevent temperature
overshoot in the part.
With travel detection and travel speeds
above 15 in./min (38cm/min), the rate
of power output is increased. In either
case the maximum power output is
limited to 300 amps per output, which
is about 20 kW with one Rolling Induc-
tor and 35 kW with two Rolling Induc-
tors.
The graph illustrates the rate at which
output power is increased with heating
time.
