Extended Functions
Function module position control
Using the connector input p2515 (position setting value) and a "1" signal at binector
input p2514 (set position actual value), a position setting value can be entered.
Warning
!
By setting the position actual value (p2514 = "1" signal), the position actual value
of the position control is held, as standard to the value of connector p2515.
Encoder increments that are received are not evaluated. If there is a position
difference, then in this state it cannot be corrected.
Parameter p0410 inverts the position actual value from the encoder. An inversion
of the axis motion can be entered using a negative value in p2505.
Commissioning using STARTER
The function module "position control" can be activated via the commissioning
Wizard or the drive configuration (configure DDS).
When the function module "basic positioner" (r0108.4 = 1) is activated, then the
function module "position control" (r0108.3) is automatically activated.
The current configuration can be checked in parameter r0108.
