Table 4.1: Par. 5-1* selection [16], [17] and [18]
[0.00] *
-100.00 - 100.00% Enter the different preset references using array programming.
Normally, 100% = value set in par. 3-03,
Maximum Reference .
However, there are exceptions if par. 3-00 is set to
Min - Max ,
[0].
Example 1:
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 com-
mand (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 − reference ×
Catchup Slowdown
100
When the input command is inactivated, the reference returns
to its original value ie. Reference = Reference + 0.
