Par. 3-02 is set to 20 and par. 3-03 is set to 50. In this case 0% = 0 and 100% = 50.
Example 2:
Par. 3-02 is set to -70 and par. 3-03 is set to 50. In this case 0% = 0 and 100% = 70.
3-11 Jog Speed [Hz]
Range: Function:
Jog speed is a fixed output speed and overrules the selected reference speed, see par. 5-1* selection [14].
If the motor is stopped while in jog mode, the jog signal acts as a start signal.
Removing the jog signal makes the motor run according to the selected configuration.
5.0 Hz [0.0 - 400.0 Hz] Select speed to function as jog speed.
3-12 Catch Up/Slow Down Value
Range: Function:
0% * [0 - 100%]
The Catch-up/Slowdown function is activated by an input command (see par. 5-1*, choice [28]/[29]). If the command
is active, the Catch-up/Slowdown value (in %) is added to the reference function as follows:
Reference = Reference + Reference ×
Catchup Slowdown
100
Reference = Reference ì Reference ×
Catchup Slowdown
100
When the input command is inactivated, the reference returns to its original value ie. Reference = Reference + 0.
3-14 Preset Relative Reference
Range: Function:
0.00% [-100.00 - 100.00%] Define fixed value in % to be added to variable value defined in par. 3-18, Relative Scaling Reference Source.
The sum of fixed and variable values (labelled Y in illustration below) is multiplied with actual reference (labelled X in
illustation). This product is added to actual reference
X + X ×
Y
100
3-15 Reference 1 Source
Option: Function:
Par. 3-15, 3-16 and 3-17 define up to three different reference signals. The sum of these reference signals defines the
actual reference.
[0] No Function No reference signal is defined.
