System Description
Internal synchro-
nous operation You can always use the MOVIDRIVE
®
range of units with "internal synchronous opera-
tion" whenever a group of motors has to be operated at a synchronous angle in relation
to one another or with an adjustable proportional ratio (electronic gear). A user-friendly
editor guides you through the startup procedure.
Note the following points:
• "Internal synchronous operation" can only be implemented with MOVIDRIVE
®
units
in application version (...-0T).
• Encoder feedback is mandatory. "Internal synchronous operation" can be imple-
mented using the following operating modes:
– MOVIDRIVE
®
compact MCV in CFC operating modes
– MOVIDRIVE
®
compact MCS in SERVO operating modes
– MOVIDRIVE
®
compact MCH in CFC or SERVO operating modes
• "Internal synchronous operation" cannot be implemented with:
– MOVIDRIVE
®
compact MCV/MCH in VFC and VFC-n-CRTL operating modes
– MOVIDRIVE
®
compact MCF
• "Internal synchronous operation" is only available in parameter set 1.
Motors and
encoders
Use the following motor types:
• For operation with MOVIDRIVE
®
compact
MCV4_A...-5_3-4-0T:
– CT/CV asynchronous servomotors with high-resolution sin/cos encoder
– DT/DV AC motor with incremental encoder, preferrably with a high-resolution
sin/cos encoder
• For operation with MOVIDRIVE
®
compact
MCS4_A...-5_3-4-0T:
– DS/CM synchronus servomotor with resolver
• For operation with MOVIDRIVE
®
compact
MCH4_A...-5_3-4-0T:
– CT/CV asynchronous servomotors with sin/cos encoder or AV1H (HIPERFACE
®
encoder)
– DT/DV AC motors with sin/cos encoder, AV1H (Hiperface
®
encoder) or RS422
encoder
– CM synchronous servomotors with AS1H/ES1H (Hiperface
®
encoder)
High-resolution speed measurement is required for optimum operation of the "internal
synchronous operation." The encoders installed as standard in CT/CV and DS/CM mo-
tors fulfill these requirements. SEW-EURODRIVE recommends using high-resolution
sin/cos encoders as incremental encoders if DT/DV motors are used.
