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.

0.23 {1.05} Jog reference
RW Uni
OL 0 to 400.0 Hz
CL 0 to 4,000.0 rpm
Enter the required value of jog frequency/speed.
The frequency/speed limits affect the drive when jogging as follows:
Frequency-limit parameter
Pr 0.01 Minimum reference clamp
Pr 0.02 Maximum reference clamp
0.24 {1.21} Preset reference 1
RW Bi
±Speed_limit_max rpm
0.25 {1.22} Preset reference 2
RW Bi
±Speed_limit_max rpm
0.26 {1.23} Preset reference 3
RW Bi
OL ±Speed_freq_max Hz/rpm
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.
0.26 {3.08} Overspeed threshold
RW Uni
CL 0 to 40,000 rpm
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.
