Output Current Control
Output Current Control with External Resistance
1. Output Current Control with External Resistance (A)
*This function can not use 1000V type.
This section describes how to set the output current zero, when the
external resistance value is infinite (open).
The output current is derived from the following formula.
Output Current [A]
=
10 ] [ Resistance External
10
] [ Current Output Max.

The output accuracy for the external resistance, is the set current ±
(1% of Rated Output Current) when 10kΩ.
Connecting
Connect the resistor between No. 8 and 20 of the external control connector (accessory).
Setting Procedures
Set the parameter to 2 (External Resistance Type A) according to the procedure on page 144.

 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.
