2.9 Start-up
Do normal start-up according chapter “Start-up” for each hoist. If the crane has been ordered with the Synchro function, it
does not need any additional actions before use. In case there is problems or synchronization is added afterwards, do
start-up according the following list.
1. Do normal start-up routine for each hoist.
2. For all drives, check that the SystemBus Boards OPT-D1 and optical cables are connected properly. Checklist:
−
The unused fibre terminals are protected with rubber pins.
−
Optical cable clamp, routing and minimum bending radius.
−
Control units cover is closed and locked.
3. Set the parameters:
−
P2.4.2. Address, one drive has to have address=1, this will function as master. Every drive should have
their own address.
−
P2.4.2. Next Address,
−
P2.4.3. Last Address
−
P2.4.4. Nominal Speed, hoisting speed from hoist rating plate
4. Check from the panel that for all drives, the first and the second digit of the V2.4.10.10 Synchro Status are now
“11xxx”. The first digit indicates that the Synchro is parameterized in use, and the second digit indicates that the
SystemBus is working properly. Power off the drives if second digit is zero, then power on and check again.
5. Activate synchronization using digital input DID1.
−
Check from the panel that for the master drive (Address=1) the V2.4.10.10 Synchro Status is now
11101, and that for all the slave drives it is 11011. The third digit indicates that the drive is a master and
the fourth digit indicates that the drive is a slave. Fifth digit indicates that synchronization is activated
from the digital input, and there are totally at least two active drives in the SystemBus.
6. For master drive, check following synchronization control parameters.
- P2.4.5 Displacement limit, default 50
- P2.4.6 Gain, default 200
- P2.4.7 Sync Activation, default 0 / During Stop.
- P2.4.8 Min Freq Offset, default 3Hz.
- P2.4.9 System Bus Speed, default 3Mbit/s.
7. Check that acceleration/deceleration ramps are identical in each drive.
8. Finally, perform a test drive with no load on. Check that:
−
There is no position difference between hooks, with smooth driving or with lots of accelerations and
decelerations.
−
V2.4.10.1 Max Pos Error in the master drive doesn’t show any constant position error.
