Preliminary work
•
Startup the master and slave drives separately in operating mode (
→
P700) VFC-n
CTRL., CFC or SERVO, in accordance with the the instructions in the MOVIDRIVE
®
MDX60B/61B operating instructions.
•
Program the terminal assignment of the master and slave according to the require-
ments of your application.
•
Activate and test the speed controlled operation of both drives.
5.4
Activating synchronous operation
Testing the
encoder signals
•
Delete any angle error (
→
green LED "SYNC" lights up) between the master and
slave:
– Set one binary input of the slave inverter to the function "Set DRS zero point." The
signal is set to "1" active.
– Change this binary input "0"
→
"1"
→
"0." The green LED "SYNC" goes out.
•
Activate synchronous operation control for the slave by setting an operating mode
with encoder feedback and synchronous operation (e.g. VFC-n CONTROL&SYNC,
CFC&SYNC, SERVO&SYNC). Initially, leave all the parameters of the synchronous
operation controller set to the default values.
•
Lock the slave drive by setting DI00 to "0" (controller inhibit).
•
Move the master drive and watch the green LED "SYNC" on DRS11B while doing so.
Following a short movement of the master drive, the LED should light up.
•
If the green LED "SYNC" does not light up, check the encoder connection between
the master and slave. In this case, the slave drive does not receive any travel infor-
mation from the master.
Synchronous
operation of both
drives when dis-
assembled
•
Delete any angle error (
→
green LED "SYNC" lights up) between the master and
slave:
– Set one binary input of the slave inverter to the function "Set DRS zero point." The
signal is set to "1" active.
– Change this binary input "0"
→
"1"
→
"0." The green LED "SYNC" goes out.
•
You can release the slave as follows:
– With DI00 = "1" (no controller inhibit)
– With DI01 = "1" (CW) or DI02 = "1" (CCW)
– With DI03 = "1" (enable)
– With X40:1 ="0" (no free-running)
•
If you start the master drive now, the slave drive will follow.
Make sure that
•
the cabling
•
the terminal assignment and
•
the safety cut-outs
have been configured correctly and are suited to the application.
Separate the drives from the machine so that both drives can be operated
mechanically, independent of each other. This prevents the system from being
damaged during startup of synchronous operation due to unintentional
movements.
