sets the destination of analog input 2.
Software V01.07.00 and later, the default is th (8)
Software V01.06.02 and earlier, the default is VOLt (6)
In modes 2 & 3 a current loop loss trip is generated if the current falls
below 3mA.
In modes 2 & 4 the analog input level goes to 0.0% if the input current
falls below 4mA.
Pr

determines whether the reference is uni-polar or bi-polar as
follows:
Enter the required value of jog frequency/speed.
The frequency/speed limits affect the drive when jogging as follows:
Open-loop
If the preset reference has been selected (see Pr
0.05
), the speed at
which the motor runs is determined by these parameters.
Closed-loop
If the speed feedback (Pr
3.02
) exceeds this level in either direction, an
overspeed trip is produced. If this parameter is set to zero, the
overspeed threshold is automatically set to 120% x
SPEED_FREQ_MAX.
Open-loop
Refer to Pr
0.24
to Pr
0.26
.
Closed-loop
Enter in Pr
0.27
the number of lines per revolution of the drive encoder.
