2. Output Current Control with External Resistance(B)
This section describes how to set the output current to zero when
the external resistance value is zero (short).
The output current is derived from the following formula.
Output Current [A]
=

The output accuracy for the external resistance, is the set current ±
(0.5% of Rated Output Current).
Connecting
Connect the resistor between No. 6 and 19 of the external control connector (accessory).
Setting Procedures
Set the parameter to 3 (External Resistance Type B) according to the procedure on page 144.

Output Current Control with External Resistance(B)
 Isolation for the wire connecting to the external control should be more than the relative ground
voltage of this product.
Otherwise, the user may receive electric shock.
 The External Resistance A, B, and C and the External Voltage cannot be used together to
control the output.
 If the external resistance opens for even a moment, the output will generate an over voltage.
