4.3.14 Modulation Subsystem

The Modulation Subsystem adjusts the output voltage or current according to the voltage

measured on the external analog input, pin 25 of JS1, named VMOD. This signal has an allowed

input range 0-10 V. Modulation requires the power supply to be configured for remote mode.

Rotary mode control or external program mode control cannot be used with this command

4.3.14.1 MOD:TYPE:SEL

This command is composed of two comma separated, modulation parameters. The first

parameter, control input, defines whether the modulation table adjusts output voltage or output

current. When the control input is set to 1, VMOD selects the modulation table to adjust output

voltage. When control input is set to 2, VMOD selects the modulation table adjust to output

current. Setting the control input to the default value of 0, disables the modulation function.

Information on programming the lookup table is provided in Section 4.3.14.2.

The second command parameter, type, defines the expression for modulating output voltage or

current. With type set to 0, table data points are used in a multiplying expression. With type set

to 1, table data points are used in an addition expression. The alternatives for modulation

expressions are illustrated in Table 4.3.

The choice of using type 0 or type 1 modulation depends on the application. Only one set point

can be modulated at any given time. The query command returns two comma separated

parameters, the control input followed by the algorithm.
