Group 31: Automatic Reset - Daikin ACS320 Operation Manual

Group 31: Automatic Reset

This group defines conditions for automatic resets. An automatic reset occurs after a particular fault is detected. The
drive holds for a set delay time, then automatically restarts. You can limit the number of resets in a specified time
period, and you can set up automatic resets for a variety of faults .
Table 38: Group 31: Automatic Reset
Code Description
3101 NR OF TRIALS
Sets the number of allowed automatic resets within a trial period defined by 3102 TRIAL TIME.
• If the number of automatic resets exceeds this limit (within the trial time), the drive prevents additional automatic resets and remains stopped .
• Starting then requires a successful reset performed from the control panel or from a source selected by 1604 FAULT RESET SEL .
Example: Three faults have occurred in the trial time . The last is reset only if the value for 3101 NR OF TRIALS is 3 or more .
3102 TRIAL TIME
Sets the time period used for counting and limiting the number of resets .
• See 3101 NR OF TRIALS .
3103 DELAY TIME
Sets the delay time between a fault detection and attempted drive restart .
• If DELAY TIME = zero, the drive resets immediately .
3104 AR OVERCURRENT
Sets the automatic reset for the overcurrent function on or off .
0 = DISABLE – Disables automatic reset .
1 = ENABLE – Enables automatic reset .
• Automatically resets the fault (OVERCURRENT) after the delay set by 3103 DELAY TIME, and the drive resumes normal operation .
3105 AR OVERVOLTAGE
Sets the automatic reset for the overvoltage function on or off .
0 = DISABLE – Disables automatic reset .
1 = ENABLE – Enables automatic reset .
• Automatically resets the fault (DC OVERVOLT) after the delay set by 3103 DELAY TIME, and the drive resumes normal operation .
3106 AR UNDERVOLTAGE
Sets the automatic reset for the undervoltage function on or off .
0 = DISABLE – Disables automatic reset .
1 = ENABLE – Enables automatic reset .
• Automatically resets the fault (DC UNDERVOLTAGE) after the delay set by 3103 DELAY TIME, and the drive resumes normal operation .
DO NOT USE!!
3107 AR AI<MIN
Sets the automatic reset for the analog input less than minimum value function on or off .
0 = DISABLE – Disables automatic reset .
1 = ENABLE – Enables automatic reset .
• Automatically resets the fault (AI<MIN) after the delay set by 3103 DELAY TIME, and the drive resumes normal operation .
Warning! When the analog input signal is restored, the drive may restart, even after a long stop . Make sure that automatic, long delayed starts will not cause
physical injury and/or damage equipment .
3108 AR EXTERNAL FLT
Sets the automatic reset for external faults function on or off .
0 = DISABLE – Disables automatic reset .
1 = ENABLE – Enables automatic reset .
• Automatically resets the fault (EXTERNAL FAULT 1 or EXTERNAL FAULT 2) after the delay set by 3103 DELAY TIME, and the drive
resumes normal operation .
