Bit 5
Flow Output V
oltage Polarity
V
elocity Byte
Pressure Byte
Description
18916
[.... 0...] [.... ....] Select
0 to +10 V
output
range for flow
command during profile*
[.... 1...] [.... ....] Select
0 to –10 V
output
range for flow
command during profile*
NOTE:
For machine configuration 3 in Ram control mode (injection, pack
hold, and plasticate profiles), bit 5 selects the output range for output
(flow/pressure) command.
Bit 6 (Plasticate only)
Auto Cushion Control
V
elocity Byte
Pressure Byte
Description
18916
[.... .0..] [.... ....] Auto
cushion control off
[.... .1..] [.... ....] Auto
cushion control on
Bit 7 (Pack
and hold only)
Velocity Transfer
V
elocity Byte
Pressure Byte
Description
1 8 9 16
[.... ..0.] [.... ....] Velocity
transfer off
[.... ..1.] [.... ....] Velocity
transfer on. This bit overrides
velocity mode set for pack and hold in
WY8 and runs pack and hold velocity in
open loop using the final velocity output
from inject as the setpoint. This
provides a bumpless transition for
velocity
.
(Not functional in machine
configuration 3.)
Bit 8 (Open
loop mode only)
Velocity
Ramping
V
elocity Byte
Pressure Byte
Description
18916
[.... ...0] [.... ....] Select
no velocity ramping
[.... ...1] [.... ....] Select
velocity ramping**
* See
download table word 225 for hold values.
**
Ramping functions only in open loop mode.
