Bit 6: Activation of the "Weighting" function block
The function block is activated by Z136.2– Mode bit 6. It operates if the input Z136.3–
Target position and its Offset Z136.4– were selected (Z136.2– Mode bit 2 = 0) only.
At the same time the function "Modulo position actual value" must be switched on by
Z121.1– Positioning general mode bit 4. If this is not the case, at the enable of the oper-
ation mode "Position control" the error code 917 ("position set value setting could not be
initialized").
The function block contains the following functions:
m Weighting
The set value can be weighted by Z121.16– Rotational position resolution.
The weighting is off at a rotational position resolution of 0.
m Load gear
An available load gear can be regarded by the parameter Z121.13– Input revolutions
and Z121.14– Output revolutions.
m Modulo position set value
The set value can be used as modulo position set value.
This function is activated by Z121.15– Modulo revolutions > 0 and Z121.16– Rota-
tional position resolution > 0. If one of these parameters is 0 the modulo handling is
switched off.
By Z121.15– is determined when the revolutions of the modulo position shall invert to
0.
The Z121.27– Set value mode determines the rotational direction. The presetting is
"shortest path". The other direction modes at "position control" make sense only if the
rotational direction of the set values shall be monitored. A movement of the set value
towards the "inhibited" direction causes a very large position change in the "free" direc
-
tion. Dependent on the Z121.11– Speed limit this leads to the error message 910
"Overspeed detected at the set value input". In general, the error reaction "Quickstop"
occurs. The error reaction can be adapted.
Bit 8: Interpolation procedure
This is where the procedure for the interpolation level "Set value cycle Cycle internal
set value interface" is entered.
The interpolation level "Cycle internal set value interface Controller cycle" is thereby
not influenced. This interpolation is defined through Parameter
Z111.6– Interpolation
mode!
NOTE!
Changes in the rotational position resolution, in the modulo revolutions and of the
gear factors are accepted only after an inhibit and a new enable of the operation
mode -4!
The Z121.17– Modulo position actual value is used when switching on the operation
mode -4 to initialize the modulo position set value (Z136.3–). Thereby, when chang-
ing the above parameters the function "Modulo position actual value" (Z121.1– bit 4)
must be switched off and then on in order to initialize again. Then the operation mode
-4 can be enabled.
