Mounting and Wiring Your 1336 IMPACT Drive 2-9
Optional Output Reactor
You can use the reactors listed in the 1336 IMPACT drive price list
for drive input and output. These reactors are specifically constructed
to accommodate IGBT inverter applications with switching
frequencies up to 20 kHz. They have a UL approved dielectric
strength of 4000 volts, opposed to a normal rating of 2500 volts. The
first two and last two turns of each coil are triple insulated to guard
against insulation breakdown resulting from high dv/dt. When using
motor line reactors, set the drive PWM frequency to its lowest value
to minimize losses in the reactors.
Important: By using an output reactor, the effective motor voltage is
lower because of the voltage drop across the reactors — this may also
reduce motor torque.
Common Mode Cores
Common mode cores help reduce the common mode noise at the
drive output and guard against interference with other electrical
equipment (such as programmable controllers, sensors, and analog
circuits). In addition, reducing the PWM carrier frequency reduces
the effects and lowers the risk of common mode noise interference.
The following table shows the common mode cores available for the
1336 IMPACT drive.
