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.
