6.7 Quick Bus Positioning
The MCO 351 is controlled by an overall control system,
e.g. a PLC system.
Parameter
19-04 Control Source
must be set to
[1] Fieldbus
to enable fieldbus operation.
Operating procedure:
1.
Referenced target position: PCD[2]msb +
PCD[3]lsb (UU)
2.
Type: PCD[1].11 (Absolute)/PCD[1].12 (Relative)
3.
Sign: PCD[1].16 (negative)
4.
Velocity: PCD[4] (RPM, on the encoder side)
5.
Acceleration: PCD[5] (% of shortest ramp time in
parameter
32-81
)
6.
Deceleration: PCD[6] (% of shortest ramp time in
parameter
32-81
)
7.
Go to target position: PCD[1].1 (Start/Stop)
8.
Position reached: PCD[1].2
Quick stop: PCD[1].8 (must always be enabled to allow
operation)
Reset error: PCD[1].2
Fieldbus communication is supported only if PCD channels
are available, such as Profibus, DeviceNet, Ethernet/IP,
CANopen etc.
A table for noting the positioning settings can be found in
chapter 8.3.1 Positioning Table
.
