Motor potentiometer (MOP)

Setpoint memory of the MOP
P1031 =...
Saves last motor potentiometer setpoint (MOP) that was active before OFF command or
power down.
0 MOP setpoint will not be stored
1 MOP setpoint will be stored (P1040 is updated)
Inhibit negative MOP setpoints
P1032 =...
0 Neg. MOP setpoint is allowed
1 Neg. MOP setpoint inhibited
Setpoint of the MOP
P1040 =...
Determines setpoint for motor potentiometer control.
MOP ramp-up and ramp-down times are defined by the parameters P1120 and P1121.
Possible parameter settings for the selection of MOP:
DIN
BOP
USS on

When defining the function of the digital inputs
(P0701 to P0703), three different types can be
selected for fixed frequencies:
15 = Direct selection (binary-coded)
5.00 Hz
10.00 Hz
15.00 Hz
16 = Direct selection + ON command
20.00 Hz
25.00 Hz
17 = Binary coded selection + ON command
30.00 Hz

NOTE
For settings 2 and 3, all parameters P1016 to
1
P1019 must be set to the selected value so that
the drive inverter accepts the ON command.

In this particular mode, the appropriate
digital input always selects the associated
fixed frequency, e.g.:
Digital input 3 = selects fixed frequency 3.
If several inputs are simultaneously active,
then these are summed. An ON command is
additionally required.
(binary-coded + On / Off1)
In this mode, the fixed frequencies are
selected as for 15, however these are
combined with an ON command.
(BCD-coded + On/ Off1)
The BCD-coded operating mode is effective
for digital inputs 1 to 3.
