Positioning - commissioning procedure
Terminal assignment:
S1IND (STOA) and S7IND (STOB): LOW signal
S2IND (Start positioning): LOW signal
S3IND (Stop positioning): LOW signal
S4IND and S5IND: encoder track B and track A or for parameterized function
S6IND: home switch or encoder zero track Z
MFI1D (JOG mode): LOW signal
Commissioning of frequency inverter:
Comply with chapter "Commissioning of Frequency Inverter",
set up configuration 240, 440 or 540,
switch on power supply,
start commissioning and diagnosis program VPlus (if not yet done for commissioning),
Set up reference system (motion distance per rotation of drive and gear factor),
Select suitable homing mode,
Select encoder source for positioning
For manual mode (JOG mode):
Set up parameters for JOG mode or use factory settings,
Release with HIGH signal on S1IND (STOA) and S7IND (STOB),
Activate JOG mode with HIGH signal at MFI1D, clockwise via S2IND, anticlockwise
via S3IND, perform function test
Entering motion profile:
In VPlus, set up the parameters of the motion blocks,
switch on speed override, in order to position at reduced speed during commissioning.
Start positioning:
Check readiness for operation: when green LED is flashing: ready for operation; if
green and red LED are flashing: ready for operation and warning message is present, repair fault,
Release with HIGH signal on S1IND (STOA) and S7IND (STOB) and start of positioning with HIGH signal on S2IND
For communication via field bus or system bus: Set up other parameters according
to operating instructions of the corresponding extension or communication module.
Motion blocks
The motion profile is defined in motion blocks, indicating the target position, speed
and acceleration. A positioning operation may comprise a maximum of 32 motion
blocks.
Discrete selection: Each of the 32 motion blocks can be selected both via logic signals and parameters (also for transfer via field bus or system bus).
Cycle: The motion blocks can be repeated or processed in a freely programmable
order.
In the motion blocks, the motion block to be processed next can be identified.
The next motion block can be activated:
- by events, e.g. via digital inputs or logic signals
- after a definable delay
In the motion block, the motion mode is selected: absolute (referred to a fixed reference position), relative (to moving distance, referred to last position approached)
or "Touch Probe" (to moving distance, referred to a sensor signal on digital input
S3IND).
