Other unit functions via RS485 interfaces
Serial Interfaces of MOVIDRIVE® B
Torque control
The slave inverter receives the torque setpoint of the master directly (the correcting
variable of the speed controller). This enables high quality load sharing, for example.
This load sharing setting should be preferred if the drive configuration permits it. Set the
torque ratio using
P751 Scaling slave setpoint
.
Example:
4.4.2
Using the RS485 interfaces in IPOS
plus®
In the IPOS
plus®
positioning and sequence control system integrated in MOVIDRIVE
®
B, you can
• directly access the process data transmitted via RS485 using the commands
GETSYS PO data
and
SETSYS PI data
.
• access process and parameter data of other SEW drives connected via RS485 using
the MOVILINK
®
command.
For this purpose, set the bus type to the value "1" for accessing the XT socket (master
functionality), and to value "2" for access via X13.
4.4.3
Using RS485 interfaces for manual operation
Manual operation of MOVIDRIVE
®
B serves as startup assistance. It is used to move
the drive for teach mode without active PLC (see chapter 8.9).
