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 (FF)
P1001 =...
Fixed frequency 1
Can be directly selected via DIN1
(P0701 = 15 16)
P1002 =... Fixed frequency 2
Can be directly selected via DIN2
(P0702 = 15, 16)
P1003 =... Fixed frequency 3
Can be directly selected via DIN3
(P0703 = 15, 16)
P1004 =... Fixed frequency 4
P1005 =... Fixed frequency 5
P1006 =... Fixed frequency 6
P1007 =... 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.
