Brief description of the startup process
Startup
•
Slave drive:
Motor with encoder and brake.
•
Slave inverter:
MOVIDRIVE
®
MDX61B with encoder option card, operating mode with encoder
feedback and synchronous operation, e.g. VFC-n CTRL.&SYNC / CFC&SYNC /
SERVO&SYNC with synchronous operation board option DRS11B.

Brief description of the startup process
Preliminary work
•
Check wiring, terminal assignment and safety cut-outs.
•
Disconnect the drives from the machines.
•
Startup master and slave separately with speed control.
•
Program binary inputs and binary outputs as necessary for the specific application.
•
Start master and slave and test speed control operation.
Test encoder
signals
•
Delete angle error between master and slave using "Set DRS zero point."
•
Set slave operating mode P700 to "Synchronous operation."
– Asynchronous motors: VFC-n CTRL&SYNC or CFC&SYNC
– Synchronous motors: SERVO&SYNC
•
Lock slave (/CONTROLLER INHIBIT DI00 = "0") and turn master.
•
LED SYNC (green) must light up. If not check the encoder connection between the
master and slave.
•
If necessary, switch on encoder monitoring.
Synchronous
operation of mas-
ter and slave with
disassembled
drives
•
Delete angle error between master and slave using "Set DRS zero point."
•
Enable slave and start the master drive. The slave follows the master.
Set synchronous
operation param-
eters
•
Master gear ratio factor (P221) and slave gear unit factor (P222) in accordance with
the gear unit reduction ratios.
Synchronous
operation of mas-
ter and slave with
assembled drives
•
Assemble and align drives.
•
Delete angle error between master and slave using "Set DRS zero point."
•
Release drives.
•
Check whether the angle error during acceleration processes is within the permitted
range (
→
MOVITOOLS
®
SCOPE or green LED SYNC).
If option DRS11B for the slave drive is replaced in MOVIDRIVE
®
MDX61B, the drives
must be realigned.
