3. Output Current Control with External Resistance(C)
*This function can not use 1000V type.
This section describes how to set the output current zero when the
external resistance value is 10kΩ.
The output current is derived from the following formula.

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 4 (External Resistance Type C) according to the procedure on page 144.

Output Current Control with External Resistance(C)
 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.
 The system is a fail safe method and is such that if the External Resistance opens, the Output
Current will become zero.
