The JOG command is the combination of the Run/Stop command with a speed reference via parameter P122
(Figure 9.12 on page 9-17).

i) ELECTRONIC POTENTIOMETER
The E.P. function enables the setting of the speed via digital inputs programmed for Accelerate E.P. and
Decelerate E.P. (Figure 9.13 on page 9-18). The basic principle of this function is similar to the sound volume
and intensity control of electronic appliances.
The operation of the E.P. function is also affected by the behavior of parameter P120, that is, if P120 = 0 the
E.P. reference initial value will be P133; if P120 = 1 the initial value will be the last reference value before the
disabling of the inverter, and if P120 = 2, the initial value will be the reference via P121 keys.
