Program features 71 Motor potentiometerThe motor potentiometer is, in effect, a counter whose value can be adjusted up anddown using two digital signals selected by parameters 22.73 Motor potentiometer upsource and 22.74 Motor potentiometer down source.When enabled by 22.71 Motor potentiometer function, the motor potentiometerassumes the value set by 22.72 Motor potentiometer initial value. Depending on themode selected in 22.71, the motor potentiometer value is either retained or reset overa power cycle.The change rate is defined in 22.75 Motor potentiometer ramp time as the time itwould take for the value to change from the minimum (22.76 Motor potentiometer minvalue) to the maximum (22.77 Motor potentiometer max value) or vice versa. If the upand down signals are simultaneously on, the motor potentiometer value does notchange.The output of the function is shown by 22.80 Motor potentiometer ref act, which candirectly be set as the reference source in the main selector parameters, or used as aninput by other source selector parameters, both in scalar and vector control.The following example shows the behavior of the motor potentiometer value.SettingsParameters 22.71…22.80 (page 160).0101022.8022.7422.7322.7722.7622.75
