  9. 9. AB Powerflex 4M Parameter Organization - Display d001 – Output Frequency Output frequency present at T1, T2 & T3 (U, V & W). d002– Commanded Frequency Value of the active frequency command. Displays the commanded frequency even if the drive is not running. d003 - Output Current The output current present at T1, T2 & T3 (U, V & W). d004 - Output Voltage d006 – Drive Status Present operating condition of the drive. The output voltage present at T1, T2 & T3 (U, V & W). d005 – DC Bus Voltage Present DC bus voltage level.
  10. 10. AB Powerflex 4M Parameter Organization d010 – Process Display The output frequency scaled by A440 [Process Factor] or by A438 [Process Time Lo] and A439 [Process Time Hi]. d012 – Control Source Displays the active source of the Start Command and Speed Command.
  11. 11. AB Powerflex 4M Parameter Organization d012 – Control In Status Status of the control terminal block control inputs. Important: Actual control commands may come from a source other than the control terminal block. d018 - Elapsed Run Time Accumulated time drive is outputting power. Time is displayed in 10-hour increments.
  12. 12. AB Powerflex 4M Parameter Organization d020 - Analog In 0-10V The present value of the voltage at I/O Terminal 13 (100.0% = 10 volts). d021 - Analog In 4-20mA The present value of the current at I/O Terminal 15 (0.0% = 4mA, 100.0% = 20mA). d022 - Drive Temperature Present operating temperature of the drive power section.
  13. 13. AB Powerflex 4M Parameter Organization - Program P101 – Motor NP Voltage Stop drive before changing this parameter. Set to the motor nameplate rated voltage. P102 – Motor NP Hertz Stop drive before changing this parameter. Set to the motor nameplate rated frequency. P103 – Motor OL Current Set to the maximum allowable motor current. P104 – Minimum Frequency Sets the lowest frequency the drive will output continuously. Min/Max: 0.0/400.0 Hz P105 – Maximum Frequency Sets the highest frequency the drive will output continuously. Min/Max: 0.0/400.0 Hz
  14. 14. AB Powerflex 4M Parameter Organization - Program P106 – Start Source Stop drive before changing this parameter. Sets the control scheme used to start the drive. P107 – Stop Mode Active stop mode for all stop sources 0“Ramp, CF”(1) (Default) Ramp to Stop. “Stop” command clears active fault. 1“Coast, CF”(1) Coast to Stop. “Stop” command clears active fault.
  15. 15. AB Powerflex 4M Parameter Organization - Program P108 – Speed Reference Sets the source of the speed reference to the drive. P109 – Acc. time Sets the rate of acceleration for all speed increases.
  16. 16. AB Powerflex 4M Parameter Organization - Program P110 – Dec. Time Sets the rate of deceleration for all speed decreases. P112 – Reset to Default Resets all parameter values to factory defaults.
  17. 17. AB Powerflex 4M Parameter Organization - Terminal t201 – Digital In1 Sel (I/O Terminal 5) T202 – Digital In2 Sel (I/O Terminal 6)
  18. 18. AB Powerflex 4M Parameter Organization - Terminal t201 – Digital In1 Sel (I/O Terminal 5) T202 – Digital In2 Sel (I/O Terminal 6)
  19. 19. AB Powerflex 4M Parameter Organization - Terminal t211 – Analog In 0 ~ 10 V Lo Sets the analog input level that corresponds to P104 [Minimum Freq] if a 010V input is used by P108 Analog inversion can be accomplished by setting this value larger than t212 [Anlg In 0-10V Hi] or by setting t201 - t202 [Digital Inx Sel] to option 15 “Anlg Invert”. t212 – Analog In 0 ~ 10 V Hi Sets the analog input level that corresponds to P105 [Maximum Freq] if a 0-10V input is used by P108 [Speed Reference]. Analog inversion can be accomplished by setting this value smaller than t211 [Anlg In 010V Lo] or by setting t201 - t202 [Digital Inx Sel] to option 15 “Anlg Invert”.
  20. 20. AB Powerflex 4M Parameter Organization - Terminal t213 – Analog In 4 ~ 20mA Lo Sets the analog input level that corresponds to P104 [Minimum Freq] if a 420mA input is used by P108 [Speed Reference]. Analog inversion can be accomplished by setting this value larger than t214 [Anlg In4-20mA Hi] or by setting t201 - t202 [Digital Inx Sel] to option 15 “Anlg Invert”. t214 – Analog In 4 ~ 20mA Hi Sets the analog input level that corresponds to P105 [Maximum Freq] if a 420mA input is used by P108 [Speed Reference]. Analog inversion can be accomplished by setting this value smaller than t213 [Anlg In4-20mA Lo] or by setting t201 - t202 [Digital Inx Sel] to option 15 “Anlg Invert”.
  21. 21. AB Powerflex 4M Parameter Organization - Terminal t221 – Relay Out Selection Sets the condition that changes the state of the output relay contacts.
  22. 22. AB Powerflex 4M Parameter Organization - Terminal t221 – Relay Out Selection Sets the condition that changes the state of the output relay contacts. t222 – Relay Out Level Sets the trip point for the digital output relay if the value of t221 [Relay Out Sel] is 6, 7, 8, 10 or 11.
