Remarks:
Bits 4 and 5: The behavior at active limit switch monitoring, when moving over
limit switch:
When overriding a hardware limit switch, a Error 906 "Negative hardware limit switch ac-
tive" or Error 907 "Positive hardware limit switch active" will be triggered.
When overriding a software limit switch, a Error 908 "Negative software limit switch ac-
tive" or Error 909 "Positive software limit switch active" will be triggered.
With setting of bit 5 the error message and error response can be switched off. In this
case only the set stop (bit
4 = 1) is executed and the drive direction is inhibited.
The subsequent behavior of the drive corresponds with the error response setting for the
corresponding error code.
The default value for these errors is "no response".
m "no response" and Bit 4 = 0:
Only the corresponding error is settled. New set values through the fieldbus continue
to be accepted. The control must perform the corresponding response.
m "no response" and Bit 4 = 1:
In addition to settling the error, a Stop is also triggered. Braking occurs drive internally
with
Z121.8– Stop delay. New set values through the fieldbus will be ignored.
After ending the Stop (speed set value = 0), the end switch errors may be confirmed.
During confirmation, the drive control synchronizes the input parameters
Z136.3– Tar-
get position and Z136.5– Target angle with the current Z136.8– Output position set
value. The higher level control must perform this as well and can then be assigned new
set values.
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 with synchronous set value setting" the error code 917 ("po-
sition set value setting could not be initialized").
The function block contains the following functions:
8 Interpolation procedure:
0: Linear interpolation
1: Square interpolation
11 … 9 Reserved
13 … 12 Factor for interpolation interval (IP Interval = Factor * Fieldbus cycle time
Z131.18–)
00: Factor = 1
01: Factor = 2
10: Factor = 4
11: Factor = 8
15 … 14 Reserved
