How to parameterize the jog
function …
As you can see in Figure 7-1 a stop signal must be triggered to activate the jog function.
When the drive has reached the speed window ± C40 the jog reference value can be
enabled by the jog enable.
To parameterize proceed as shown below:
• Set a source for the stop signal in D102 if you haven't yet selected the signal source.
• Select the source of the jog enable in D105. The jog reference value is not used until
the jog enable becomes active. The jog enable can also be implemented via D55 Bit 3
and a simultaneously queued additional enable 2. (See chap. 9.4.)
• Parameterize the sources for the jog+ and jog- signals in D106 and D107. If neither
signal is active the jog reference value is 0. If jog+ is active, the jog reference value is
passed on unchanged. If jog- is active the jog reference value is negated. If both
signals are on, the reference value is set to 0.
• Enter the ramp of the jog reference value in D28.
How to parameterize the jog
reference value …
After making the settings on page 4 of the Assistant, go to page 3.7 (Figure 7-2) to
parameterize the jog reference value. Proceed as shown below:
• Set the signal source of the jog reference value in D135. The reference value is read
from D235 in fieldbus operation (D135 = 4:parameter) or as a constant value.
• If you selected an analog input in D135 additional parameters are indicated. Set the
input with these parameters (e.g., analog input offset).
• Scale the characteristic curve with array parameters D51.3 to D54.3. Scaling specifies
the correct counter-value in user units for each input value.
Example for external reference value:
D51.3 = 0.5 V, D52.3 = 8 V
D53.3 = 100 Rpm, D54.3 = 1500 Rpm
This setting means that 100 Rpm is specified for a reference value of 0.5 V and 1500
Rpm for 8 V. The curve is calculated linearly from these two points.
NOTE
Since triggering the stop function in torque mode causes a switch to speed control
(regardless of the settings on page 1 of the Comfort Reference Value Assistant), jog
mode is only possible with speed control.
