These limits are of importance, for example, when defining the gain, I-time, and D-time for the PID controller.
10.118 (ID 360) PID Controller Maximum Limit
Location in the menu: P2.2.31 (PID Control Application)
Use this parameter to set the maximum limit for the PID controller output.
Limit setting: –1600.0% (of f
max
) < parameter ID 359 < parameter ID 360 < 1600.0% (of f
max
).
These limits are of importance, for example, when defining the gain, I-time, and D-time for the PID controller.
10.119 (ID 361) Free Analog Input, Signal Selection
Location in the menu:
P2.2.20 (Local/Remote Control Application)
P2.2.17 (Multi-Step Speed Control Application)
Use this parameter to select the input signal for an analog input that is not in use for reference signal.
10.120 (ID 362) Free Analog Input, Function
Location in the menu:
P2.2.21
(Local/Remote Control Application)
P2.2.18
(Multi-Step Speed Control Application)
Use this parameter to select the function for an analog input that is not in use for reference signal.

1 Reduces motor current
limit (ID 107) This signal adjusts the maximum motor current between 0 and maximum limit set
with ID 107. See
Illustration 51 .
2 Reduces DC brake current DC brake current can be reduced with the free analog input signal between zero cur-
rent and the current set with the parameter ID 507. See
Illustration 52 .
3 Reduces acceleration and
deceleration times Acceleration and deceleration times can be reduced with the free analog input signal
according to the following formulas: Reduced time = set acc./deceler. time (parame-
ters ID103, ID104; ID502, ID503) divided by the factor R in
Illustration 53 .
4 Reduces torque supervi-
sion limit Set supervision limit can be reduced with the free analog input signal between 0 and
set torque limit supervision value (ID349), see
Illustration 54 .
