Application Control Selection
Constant periphery control and synchronization operation (simultaneous start synchronization, wait
synchronization) can be selected as an application.
The constant peripheral speed control suppresses an increase in peripheral speed (line speed) resulting
from the increasing radius of the take-up roll in the winder system.
Synchronization operation takes positional synchronization of several shafts of the conveyor. For details of
synchronization operation, see the instruction manual of the PG interface card.
Application control selection (d41)
d41 sets whether to enable or disable constant peripheral speed control and synchronization operation
(simultaneous start synchronization, wait synchronization).
Table 5.4-169
Data for d41 Function
0 Disable (Standard control)
1 Enable (Constant peripheral speed control)
Note: It is valid only when "3: V/f control with speed sensor"
or "4: Dynamic torque vector control with speed sensor" is selected for the
control method selection 1 to 4 (F42, A14, b14, or r14).
2 Operation (simultaneous start synchronization (no Z phase))
3 Operation (wait synchronization)
4 Operation (simultaneous start synchronization (Z phase))
Machinery configuration and settings
When the machinery of the winder has the configuration as shown below, it is necessary to set the following
function code.
- Speed reduction ratio between motor shaft
and take-up roll shaft is a:b
- Speed reduction ratio between speed
detector shaft and encoder shaft is c:d
- Radius r
1
of winder before winding [m]
- Radius r
2
of speed detection section [m]
