Process data description
SEW Unit Profile
SLIP
Set to
SLIP
means the MOVIDRIVE
®
inverter interprets the trans-
mitted process output data word as slip compensation value.
Specifying the slip compensation via fieldbus automatically dis-
ables parameters
P324 Slip compensation 1
and
P334 Slip com-
pensation 2
.
Specifying the slip compensation via process data channel is only
technically meaningful in the
VFC N-CONTROL
operating mode
because the torque can be influenced directly by changing the slip
compensation.
The value range of this slip compensation value is identical with
the value range of parameter
P324 Slip compensation 1
and cor-
responds to a speed range of 0 - 500 rpm.
If the slip specified using process data is outside this value range,
the maximum will take effect when the minimum and maximum
values are exceeded.
1 digit = 0.2 / min
RAMP
Set to
RAMP
, the MOVIDRIVE
®
inverter considers the transmit-
ted setpoint value to be an acceleration or deceleration ramp. The
specified value corresponds to a time in ms and refers to a speed
change of 3000 rpm.
The rapid stop and emergency stop function is not affected by this
process ramp. When transmitting the process ramp via the field-
bus system, ramps t11, t12, t21 and t22 become ineffective.
1 digit = 1 ms
CONTROL WORD
1 / CONTROL
WORD 2
The assignment of process output data with control word 1 or 2
allows for activating nearly all the drive functions via fieldbus sys-
tem. For a description of control words 1 and 2, please refer to the
chapter "Control word definition".
SPEED [%]
Set to
SPEED [%]
means the MOVIDRIVE
®
inverter interprets the
setpoint transmitted in this process data word as speed setpoint in
percent.
The relative speed setpoint always refers to the currently applica-
ble maximum speed limit, which means either P302/312 or MAX.
SPEED or PO speed limit.
4000
hex
= 100 % n
max
IPOS PO-DATA
The setting
IPOS PO-DATA
has the effect that the drive inverter
does not use this process output data word for processing set-
points. The inverter system ignores the content of the process
output data word programmed to
IPOS-PO-DATA
and is available
for sole processing in the IPOS
plus®
control program.
Within IPOS
plus®
, you can use the command
GetSys PO-Data
to
directly access the process output data of the communciation
interfaces. For more detailed information, refer to the IPOS
plus®
positioning and sequence control system manual.
Three words
with individually
coded 16 bits
each can be
exchanged
between the
higher-level
controller and
IPOS
plus®
.
