P0757[1] to P0760[1]
Set the scaling of the actual value for analog input 2
(see section 6.3.2 Analog inputs).
P2264
Set to 755[1] (defines AIN2as actual value).
P2271
Define the reaction of the PID controller to the actual values (0=heating,
1=cooling).
P2200
Enable the PID controller (0=disable, 1=enable).
r2262
Check for setpoint (scaled PID setpoint in %).
Note: VSD must be set to automatic control.
DIN1 must be set to ON.
r2272
Check for actual value (scaled PID actual value in %).
Set and optimize P2280 PID proportional gain and P2285 PID integration time.
Changeover to automatic control.
6.4.2 Belt failure detection without sensor (P2181)

Motor
This function allows for monitoring power transmission components such as drive belts.
The function can also detect motor overload, e.g. in the case of jam.
The actual frequency / torque curve is compared to a preprogrammed tolerance band
(see P2182 to P2190) as part of this function. If the actual curve is outside the
tolerance band, a warning or error message is generated.
