Zero 
The zero setting is used in limiting the minimum output value of the PIDA function. If the PID 
algorithm calculates an output quantity that is less than the value stored in zero, the output 
quantity is set equal to the value stored in zero. The zero setting should always be less than 
the full setting. 
Cycle Time 
The cycle time is the floating-point value of the PID algorithm execution period measured in 
seconds. Any value greater than or equal to 0.001 seconds (1 ms) may be specified. If the 
cycle time specified is less than the scan time of the TelePACE program, the program scan 
time becomes the PID cycle time. 
Manual Mode 
The manual mode output is the value that the output is set to when the PIDA function is in 
manual mode.
