Failure to install the correct value
for C
L
may result in damage to the
amplifier or significant loss of
performance.
J3 is a 2-pin cage clamp connector that accepts the current loop tuning capacitors. The value of C
L
depends on the
amplifier model number, the applied voltage, and the motor line-to-line inductance (L). You can measure the value
of L, check the data sheets, or contact your Regional Office for assistance in determining this value.
Calculate the value of the capacitor according to Equation 4.1 or 4.2, depending on the model number of your unit:

V is the applied voltage (volts)
L is the line-to-line inductance (mH).
You can round these values to the nearest 20% so you can use a standard capacitor value. Use multilayer ceramic
capacitors such as Panasonic ECU series. Do not use polarized capacitors such as electrolytic or tantalum capacitors.
Use multilayer ceramic
capacitors for C
L
. Do not use
polarized capacitors. Failure
to use the correct type of
capacitor may lead to
unpredictable performance or
damage to the system.
Prepare the capacitor by clipping the leads to 12mm (0.5") and bending the leads out so they are approximately 5mm
(0.2") apart.

Failure to install the correct
value for R
L
may result in
damage to the amplifier or
significant loss of
performance.
J4 is a 2-pin cage clamp connector that accepts the current loop tuning resistor. The value of R
L
depends on the
amplifier model number, the applied voltage, and L, the motor line-to-line inductance. You can measure the value of
L or contact your Regional Office for assistance in determining this value.
Calculate the value of the resistor according to Equation 4.3 or 4.4, depending on the model number of your unit:
