Start
Do MD 5706 and
MD 5707 (v , v )
set act
have the same sign
when the drive starts?
yes, but fails with error message
Change MD 32110: ENC_FEEDBACK_POL (actual value sign)
or
invert manipulated voltage MD 5476 and actual value sensing MD 5011.
Step 2
Fig. 3-17 Start-up flow chart, Determine control direction
When the cylinder piston moves in the A ³ B direction (flow Q > 0) , the actual
velocity value V must be positive.
act
This definition must be made in the drive for the associated functionality of
S
velocity controller adaptation and
S
force limitation.
zwingend erforderlich.
Step 2 (adjust sign of actual velocity value)
Input a small positive valve manipulated voltage (function generator)
or
traverse the drive in JOG mode to move the cylinder piston from the A to B end!
Is cylinder piston
A traversing ! B
and is MD 5707
positive?
yes
Step 3
Fig. 3-18 Start-up flow chart, definition of drive travel direction
3.9 Fine adjustment and optimization
no
Invert manipulated voltage MD 5476
Invert control signal (change MD 5476 bit 0)
and
no invert actual value (change MD 5011 bit 0)
and
change MD 32110: ENC_FEEDBACK_POL
(actual value sign)
