Pr 0.20 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 0.22 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.
