Coding of process data
Startup with Communications Interface / Fieldbus
Process output
data Process output data are sent from the master controller to the MOVIMOT
®
inverter (con-
trol information and setpoints). However, they only come into effect in MOVIMOT
®
if the
RS-485 address in MOVIMOT
®
(DIP switches S1/1 to S1/4) is set to a value other than
0. MOVIMOT
®
can be controlled with the following process output data:
• PO1: Control word
• PO2: Speed [%] (setpoint)
• PO3: Ramp
Control word, bits
0...2 The "Enable" control command is specified with bits 0...2 by entering the control word =
0006
hex
. The CW and/or CCW input terminal must also be set to +24 V (jumpered) to
enable the MOVIMOT
®
unit.
The "Stop" control command is issued by resetting bit 2 = "0." You should use the stop
command 0002
hex
to ensure compatibility with other SEW inverter products. However,
MOVIMOT
®
always triggers a stop with the current ramp whenever bit 2 = "0," irrespec-
tive of the status of bit 0 and bit 1.
Control word bit 6
= Reset In the event of a malfunction, the fault can be acknowledged with bit 6 = "1" (Reset). The
value of unassigned control bits should be 0 to ensure compatibility.
Speed [%] The speed setpoint is specified as a percentage value in reference to the maximum
speed set with the f1 setpoint potentiometer.

, CCW rotation:
Calculation: –80 % / 0.0061 = –13115

= CCC5
hex
Ramp If the process data exchange takes place using three process data words, the current
integrator ramp is transmitted in process output data word PO3 . The integrator ramp set
with switch t1 is used if MOVIMOT
®
is controlled by two process data.
Coding: 1 digit = 1 ms
Range: 100...10000 ms
Example: 2.0 s = 2000 ms = 2000
