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 set up
automatic resets for a variety of faults.
Code Description
3101 NUMBER 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
3102 TRIAL TIME
Sets the time period used for counting and limiting the number of resets.
• See 3101
NUMBER OF TRIALS
3103 DELAY TIME
Sets the delay time between a fault detection and attempted drive restart.
• If = zero, the drive resets immediately.
DELAY TIME
3104 AR OVERCURRENT
Sets the automatic reset for the overcurrent function on or off.
0 = – Disables automatic reset.
DISABLE
1 = – Enables automatic reset.
ENABLE
• Automatically resets the fault (
normal operation.
3105 AR OVERVOLTAGE
Sets the automatic reset for the overvoltage function on or off.
0 = – Disables automatic reset.
DISABLE
1 = – Enables automatic reset.
ENABLE
• Automatically resets the fault (
normal operation.
3106 AR UNDERVOLTAGE
Sets the automatic reset for the undervoltage function on or off.
0 = – Disables automatic reset.
DISABLE
1 = – Enables automatic reset.
ENABLE
• Automatically resets the fault (
normal operation.
3107 AR AI<MIN
Sets the automatic reset for the analog input less than minimum value function on or off.
0 = – Disables automatic reset.
DISABLE
1 = – Enables automatic reset.
ENABLE
• Automatically resets the fault (
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 = – Disables automatic reset.
DISABLE
1 = – Enables automatic reset.
ENABLE
• Automatically resets the fault (
resumes normal operation.
