JOG function: JOG Mode and motorpotentiometer
TAB1
If the JOG is enabled the output frequency may be controlled by the keyboard (INC
and DEC buttons).
The frequency control in the JOG Mode is possible after the enable operation is done
and by returning to TAB1, function 1.
The JOG Mode enable operation is signaled by the alternate visualization of the para-
meter value and of the "JOG" message. The impased value in TAB1, function 1 isn’t
savable.
When the JOG function is disabled, the inverter returns to the output frequency
determined by the speed reference signal or by an eventually preset frequency.
With the "motorpotentiometer" function enabled (JOG MPt), the frequency control is
made by terminal 25 (increase frequency) and terminal 26 (decrease frequency).
MPt1: the impased frequency isn’t saved.
MPt2: the impased frequency is automatically saved after 2.5 seconds. After a
restart the inverter returns to this frequency.
Enabling a preset frequency, this frequency is acquired by the motorpotentiometer
even if the frequency is in the skip-band frequencies or is out of range f
max
or f
min
.
In the first case the inverter returns to the higher or the lower frequency of the skip-
band in function of the input direction in the skip-band and immediatly after the preset
frequency is disabled. In the second case the output frequency returns to f
max
or f
min
immediatly after the motorpotentiometer function is disabled.
Functioning modes:
a) Frequency control by the motorpotentiometer and control of the rotation sense by
the REVERSING input terminal 15
(TAB2, SUBREF, function REF = 1, 3, 4 or 5)
If the rotation sense doesn’t corrispond to the sense of the motor, the output
frequency remains the same and the inverter signals "MPtFault".
b) Frequency and rotation sense control by the motorpotentiometer
(TAB2, SUBREF, function REF = 2)
Range: ON, OFF
MPt1, MPt2
