2.0 Changes from Standard Product 
 

2.1 Enhanced PID versus Standard Software 

Feature 

Enhanced 

PID 

Standard 

Software 

Full Range PID (2-input) 

 

 

PID + Frequency Reference Capable (3-input) 

 

 

PID x Frequency Reference Capable (3-input) 

 

 

PID Setpoint Offset Parameter 

 

 

PID + Trim is Accomplished Algebraically, Regardless of Commanded 
Direction 

 

 

Frequency Reference as PID Setpoint 

 

 

Parameter B5-19 “PID Setpoint” can be changed during running 

 

 

Independent Digital PID Setpoint 

 

 

Independent Digital PID Setpoint (changeable during run) 

 

 

Multiple PID Setpoint Sources (digital preset, analog, pulse input, Modbus 
RTU, option card) 

 

 

Setpoint Ramp (when PID setpoint is from frequency reference) 

 

 

Setpoint Ramp (all PID setpoints, regardless of source) 

 

 

Multiple PID Feedback Sources (analog, pulse input) 

 

 

Feedback Detection (high, low, on-delay, off-delay, digital output, alarm, 
fault, during run, always detected) 

 

 

PID Monitors with User Units (scaled using parameter O1-03) 

 

 

Detailed PID Monitors (proportional, integral, derivative) 

 

 

Integral Hold Digital Input 

 

 

Positive Integral Hold Digital Input (integrator can only decrease) 

 

 

Negative Integral Hold Digital Input (integrator can only increase) 

 

 

Integral term is lower-limited to PID minimum output 

 

 

Integral term is held during sleep and the sleep minimum off time 

 

 

PID Output Limit 

 

 

Indep / - PID Output Limits (B5-06 PID limit now functions only as a 
PID upper limit) 

 

 

PID Output Gain can be proportional to the frequency reference 

 

 

PID Output Gain (0.01 Resolution, instead of 0.1) 

 

 

Independent “Sleep Delay” and “Wake-up Delay” parameters 

 

 

Increased range for sleep mode timers (0.0 ~ 600.0 sec) 

 

 

Minimum sleep time parameter 

 

 

Parameters O1-01 and O1-02 have been removed. Parameters P2-09 and 
P2-10 have taken their place 

 

 

Parameter O1-03 controls the units & scaling for U1-01, D1-XX, and U1-90 
thru U1-96 

 

 

Parameter P2-10 controls the units & scaling for U1-02, U1-05, U1-20,  and 
U1-46 

 

 

Parameter P2-09 controls the displayed keypad custom units for D1-XX, 
U1-01, U1-02, U1-05, U1-20, U1-46, and U1-90 thru U1-96 

 

 

Keypad monitors are now displayed in a different order:  U1-01 -> U1-90 -> 
U1-02 -> U1-03 -> ….. U1-96 -> U1-01 

 

 

PID Setpoint (U1-01), PID Feedback (U1-90), and Output Frequency (U1-
02) are displayed at power-up and return to drive mode 

 

 

Multi-function digital output for controlling the “Blowdown” valve.  When the 
“Blowdown” valve is energized, the air compressor can make air. Controlled 
by PID feedback level, drive run status, and delay timers. 

 

 

 

 

3. Limitations 

None.
