1.4 New machine parameters
24
New: MP118, MP119 bit 4, bit 5 – Select encoder for safety functions of
functional safety (FS)
These machine parameters have been introduced as a preparation for future
expansions.
Removed: MP734 – Interpolating non-linear axis error compensation
The nominal axis value is now taken into account by default in direction-
dependent axis-error compensation. MP709 (time constant for backlash
compensation) is used as a filter for the compensation value. MP734 has
therefore been removed.
New: MP1061.0, MP1061.1
MP1061.0 – Path acceleration for machining feed rate
MP1061.1 – Path acceleration for rapid traverse
MP1061 (Limitation of path acceleration) was divided into the two indices
MP1061.0 (Path acceleration for machining feed rate) and MP 1061.1 (Path
acceleration for rapid traverse). This division enables you to enter a lower
value for the acceleration at machining feed rate, which makes it possible to
optimize the behavior of drives with regard to backlash compensation.
Input: 0.001 to 500 [m/s
Enhanced: MP1350.x – Functional sequence for reference mark
traverse
The new input value 8 makes it possible to reference incremental encoders
with EnDat 2.2 protocol. With these encoders the absolute value is not
available after switch-on, so that reference marks must be traversed.
If this type of encoder is connected to the position input, bit 3 of MP118.x
must be set. This type of encoder cannot be used at the speed encoder
input yet.
Input:
8: Incremental encoder with EnDat 2.2 interface, reference run
required
New: MP1358.x – Multiturn information
MP1358 is used to activate axis-specific evaluation of the multiturn
information on the respective encoders.
The reference position of the axis can be read out as usual with PLC Module
9041. If MP1358.x = 1, the return value is the position of the encoder plus
the multiturn information (e.g. 730 degrees) plus the value in MP960.x. As
this return value of the module now also includes the multiturn information
of the encoder, this needs to be considered when defining MP960.x and
MP1356.x.
Input:
%0000000000000000000000
0 = Do not evaluate multiturn information
1 = Evaluate multiturn information
New: MP2206.x – Type of speed encoder
Input:
12: EnDat2.2 incremental, position encoder (e.g. LIP 200)
19: EnDat 2.2 incremental, speed encoder
(e.g. ERM + EIB)
Enhanced: MP2223 – Special controller functions
Bit 2 of <Mode> of PLC Module 9173 (speed-dependent wye/delta
switchover) is used to set whether readiness of the current controller is to
be waited for during restart. Now bit 7 of MP2223 can be set as an
alternative.
Input:
Bit 7
0 = Wait for readiness of current controller
1 = Do not wait for readiness of current controller
