12.10 Rules for wiring with DRIVE-CLiQ
17. Mixed operation of control cycles:
18. Operation with Voltage Sensing Module (VSM):
19. At a drive object "SERVO" or "VECTOR", up to three encoder data sets can be created
20. A maximum of 24 drive objects (DOs) can be connected.
21. At the CU320-2 Control Unit, a maximum of 16 Terminal Modules can be connected.
22. At the CU310-2 Control unit a maximum of 8 Terminal Modules, type TM15BASE and
23. At the CU310-2 Control Unit, a maximum of 3 Terminal Modules, type TM15, TM17 or
24. Cycle times with TM31
Note
A Double Motor Module, one DMC20, one DME20, one TM54F and one CUA32 each
correspond to two DRIVE-CLiQ participants. This also applies to Double Motor Modules,
at which just one drive is configured.
25. The communication basic clock cycles (p0115[0] and p4099) of all components that are
748
The following combinations are permissible:
– Servo with 62.5 µs and servo with 125 µs
– Servo with 125 µs servo with 250 µs
– Vector with 250 µs and vector with 500 µs
– Exactly 1 Voltage Sensing Module (VSM) may be connected to one Line Module.
Exception: If the "Line transformer" function module is activated, a second VSM may
be connected.
– A maximum of 2 VSMs may be connected to one Motor Module.
– The VSM must be connected to a free DRIVE-CLiQ socket of the associated Line
Modules or Motor Modules (to support automatic assignment of the VSM).
for each drive data set. The maximum number of encoder data sets depends on the
quantity structure and the current controller clock cycle:
– For a quantity structure of 6 axes in servo control with a controller cycle of 125 μs and
one Line Module, it is permissible to connect a maximum of 9 encoders.
– For 5 axes in servo control with a current controller cycle of 125 µs, a maximum of 15
encoders can be connected.
Note: If a TM15 Base, TM31, TM54F or a TM41 is connected, it is necessary to reduce
the number of connected standard axes.
TM31 can be connected.
TM41 can be connected.
A maximum of 3 Terminal Modules 31 (TM31) can be connected for a 2 ms time slice.
connected to a DRIVE-CLiQ line must be divisible by one another with an integer result.
– The smallest communication basic clock cycle is 125 µs.
– The exception are a maximum of 3 servo-controlled axes with 62.5 µs communication
basic clock cycle or a servo-controlled axis with 31.25 µs communication basic clock
cycle.
