Code Modbus ID Parameter Application RO/RW
P8.3.2.11 1415 PID2 Set Point1 Comp Max 2,3 RW
Use this paramter to set the maximum compensation for the PID setpoint value that is applied to the
output frequency of the drive is at its maximum frequency level. This value is added to the actual
setpoint value as a function of the output frequency.
Set Point Compensation = comp max * (output freq–min freq)/(max freq–min freq).
P8.2.2 2546 FB PID2 Set Point 1 2,3 RW
PID Set point value from Network. Can be assigned to PID Set Point Source
P8.3.3.1 1383 PID2 Set Point 2 Source 2,3 RW
Use this parameter to define the source of the PID set point value. This can either be an internal preset
value, keypad set point, analog signal or Fieldbus message.
P8.3.3.2 1384 PID2 Set Point 2 Min 2,3 RW
Use this parameter to set the minimum value for the set point 2 source.
P8.3.3.3 1385 PID2 Set Point 2 Max 2,3 RW
Use this parameter to set the maximum value for the set point 2 source.
P8.3.3.4 1386 PID2 Set Point 2 Sleep Enable 2,3 RW
Use this parameter to enable PID Set Point Sleep mode function. When enabled this function will disable
the output when the frequency drops below the sleep frequency for the sleep delay time. The output re
engages when feedback rises above the wakeup level. When the function is disabled the drive will run
at the minimum or maximum defined speed.
P8.3.3.5 2399 PID2 Set Point 2 Sleep Unit Sel 2,3 RW
Use this parameter to define the variable used when going into the sleep mode.
0 = Output Frequency
1 = Motor Speed
2 = Motor Current
3 = PID1 Feedback
P8.3.3.6 2456 PID2 Set Point 2 Sleep Level 2,3 RW
Use this parameter to set the level of which the unit value is used to look at to go into the sleep mode.
When the unit drops below or goes above this level for the sleep delay time it will put the drive into the
sleep mode.
P8.3.3.7 1388 PID2 Set Point 2 Sleep Delay 2,3 RW
Use this parameter sets the minimum time after the variable drops below the Sleep level for this amount
of time that the output will shutoff.
P8.3.3.8 1389 PID2 Set Point 2 WakeUp Level 2,3 RW
Use this parameter to set the level for the drive wakes up form the sleep mode condition. This level is
variable based off the wake up action selection.
P8.3.3.9 1391 PID2 Set Point 2 Boost 2,3 RW
Use this parameter to set the value the set point can be boosted when going into sleep mode.
This is an additive variable that will add to the setpoint before drive output goes to sleep to prevent
premature cycling.
P8.3.3.10 1416 PID2 Set Point 2 Comp Enable 2,3 RW
Use this parameter to enables pressure loss compensation for set point 2 signal value. This is
used in pump systems to compensate the pressure loss that occurs at the end of the pipe line due to
the liquid flow.
