– Mixed operation of servo control and vector control is not permissible.
– Mixed operation of servo control and U/f control is permissible.
– Mixed operation of vector control and U/f control is permissible.
The following combinations are permissible:
– Servo control with 62.5 µs and servo control with 125 µs
– Servo control with 125 µs and servo control with 250 µs
– Vector control with 250 µs and vector control with 500 µs
– If the function module for line infeed is activated, then a second or third Voltage
Sensing Module (VSM) can be connected to a Line 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 12 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.
