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

The output accuracy for the external resistance, is the set voltage ±
(0.2% of Rated Output Voltage) when 10kΩ.
Connection
Connect the resistor between No. 7 and 20 of the external control connector (accessory).
Setting Procedures
Set the parameter to 2 (External Resistance Type A) according to the procedure on page138.

 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.
