activated.
When this parameter is set to one, the position controller (see menu 13) is enabled (Pr
13.10
= 1) and the local position reference source is selected
(Pr
13.04
= 4 (LocAL)) during the period when the brake is released until the end of the delay, and again after the brake is applied ready for the next
start. Provided the default non-absolute mode is selected, the position controller can help to limit the movement of the motor when the brake is
released. When parameter Pr
12.49
is changed from one to zero, Pr
13.04
and Pr
13.10
are automatically set to zero.
2
Jog
override
When this parameter is set to two, the jog inputs to the sequencer take priority over the run inputs during the period when the brake is released until
the end of the delay, and again after the brake is applied ready for the next start. This allows the user to use the jog reference to pick up the load and
then switch to the selected run reference when the brake is off.
(Pr
5.54
) is above 80 %.
When Pr
12.51
is a 1 the internal field controller does not control this parameter. An external field controller can then be used to control Pr
12.50
.
When Pr
12.51
= 1,
Pr
12.50
is controlled by an external field controller.
