3.1 Drive variants
®
Overview of the variants
The following table lists the three variants and the peripheral conditions for their application:
Parallel connection Master/slave mode Mixed mode
• All motors are powered by one inverter.
As a result, there is only one inverter to
start up.
• Less time and effort spent on
installation and lower unit costs.
• One motor per inverter.
• Can be implemented with
asynchronous or synchronous motors.
• More than six motors can be included
in the master/slave combination.
• It is also possible with less rigid shaft
connectionsorshaftconnectionswhich
are subject to play.
• More than six motors can be included
in the particular master/slave
combination.
• Each group of motors is powered by
one inverter, which means less time
and effort has to be spent on startup.
• Less time and effort spent on
installation and lower unit costs.
Only possible with asynchronous motors. Asynchronous or synchronous motors
possible. Only possible with asynchronous motors.
Up to six motors can be connected in
parallel. Operation is possible with more than six motors. Operation is possible with more than six
motors, although no more than six motors
per parallel connection.
Sufficiently rigid shaft connection required:
→ZP×∆ϕ ≤20°. No particular requirement in terms of the
rigidity of the shaft connection. Sufficiently rigid shaft connection required
between the motors connected in parallel:
→ZP×∆ϕ ≤20°.
Possible operating modes:
• VFC
• VFC-n-CONTROL
•CFC
Possible operating modes:
• Master: CFC or SERVO
• Slave: CFC & M-CONTROL or SERVO
& M-CTRL.
Possible operating modes:
• Master: CFC
• Slave: CFC & M-CONTROL
Operation without a tachometer is possible. Tachometer required on each motor. Tachometer required on one motor in each
parallel connection.
