6 Start-Up and Operation

Version: 1.0.0
MP124E
V-273 VC Linear Actuator
INFORMATION
The C-413 controller sets the control value of the axis to the value of the
AutoZeroResult parameter (ID 0x07000A03) when the servo mode is switched off.
When an AutoZero procedure has been successfully performed, the parameter value
is set so that the V-273 compensates for the weight force of the moving mass with
the corresponding control value (important with a vertically aligned motion axis).
Further information can be found in the user manual of the C-413 controller.
INFORMATION
The repeatability of the positioning is only ensured when the reference point switch is
always approached from the same side. Recommended controllers from PI fulfill this
requirement with their automatic direction detection for reference moves to the
reference point switch.
INFORMATION
The force sensor of the V-273.431 model works as an incremental sensor. When the
controller is switched on or rebooted, the connected force sensor always measures
0 N, regardless of the actual force exerted on the force sensor.
In order to allow an absolute force measurement, ensure that
no
force acts on
the contact piece of the force sensor when the controller is switched on or
rebooted.
6.2 Starting Up the V-273 with the C-413 Controller
NOTICE
Unexpected motions!
The V-273 can carry out unexpected motions after the controller is switched on or
rebooted. Unexpected motions can lead to damage from collisions.
Before
connecting the V-273, check whether the controller is configured for
automatic execution of the reference move or the AutoZero procedure; see user
manual of the controller.
