frequency).
P2235[0...2] BI: Enable PID-MOP

Bin
3
Defines source of UP command.
Dependency: To change setpoint:
- Configure a digital input as source
- Use UP / DOWN key on operator panel.
Notice: If this command is enabled by short pulses of less than 1 second, the frequency is changed in steps of 0.2
% (P0310). When the signal is enabled longer than 1 second the ramp generator accelerates with the rate
of P2247.
P2236[0...2] BI: Enable PID-MOP
(DOWN-cmd)
- 19.14 T - CDS U32 /
Bin
3
Defines source of DOWN command.
Dependency: See P2235
Notice:
If this command is enabled by short pulses of less than 1 second, the frequency is changed in steps of 0.2
% (P0310). When the signal is enabled longer than 1 second the ramp generator decelerates with the rate
of P2248.
P2240[0...2] Setpoint of PID-MOP [%] -200.00 -
200.00
10.00 U, T - DDS Float 2
Setpoint of the motor potentiometer. Allows user to set a digital PID setpoint in [%].
Note: P2240 = 100 % corresponds to 4000 hex.
The start value gets active (for the MOP output) only at the start of the MOP. P2231 influences the start
value behavior as follows:
•
P2231 = 0:
P2240 gets immediately active in the OFF-state and when changed in the ON-state, it gets active after
the next OFF and ON cycle.
• P2231 = 1:
The last MOP output before stop is stored as starting value, since storing is selected, so a change of
P2240 while in ON-state has no effect. In OFF-state P2240 can be changed.
• P2231 = 2:
The MOP is active every time, so the change of P2240 affects after the next power cycle or a change
of P2231 to 0.

3
Sets the signal source to change over from manual to automatic mode. If using the motorized
potentiometer in the manual mode the setpoint is changed using two signals for up and down, e.g. P2235
and P2236.
If using the automatic mode the setpoint must be interconnected via the connector input (P2242).
0: manually
1: automatically
