6.2.8 Motor potentiometer (MOP)
P1031 =...
Setpoint memory of the MOP
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)
P1032 =...
Inhibit negative MOP setpoints
0 Neg. MOP setpoint is allowed
1 Neg. MOP setpoint inhibited
P1040 =...
Setpoint of the MOP
Determines setpoint for motor potentiometer control.
MOP ramp-up and ramp-down times are defined by the parameters P1120 and P1121.

Fixed frequency 7
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)
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.
16 = Direct selection + ON command
(binary-coded + On / Off1)
In this mode, the fixed frequencies are
selected as for 15, however these are
combined with an ON command.
17 = Binary coded selection + ON command
(BCD-coded + On/ Off1)
The BCD-coded operating mode is effective
for digital inputs 1 to 3.
P1016 =...
Fixed frequency code –
Bit 0
Defines the selection method for fixed
frequencies.
P1017 =...
Fixed frequency code –
Bit 1
P1018 =...
Fixed frequency code –
Bit 2
1 Direct selection
2 Direct selection + ON command
3 Binary coded selection + ON command
NOTE
For settings 2 and 3, all parameters P1016 to
P1019 must be set to the selected value so that
the drive inverter accepts the ON command.
