10.354 (ID 722) Automatic Restart: Number of Tries after Overcurrent Trip
Location in the menu: P2.8.6 (Standard Application, Local/Remote Control Application, Multi-step Speed Control Application, PID
Control Application, Multi-purpose Control Application, Pump and Fan Control Application)
Use this parameter to set how many automatic restarts the AC drive can make during the set trial time after an overcurrent fault.
IGBT temp fault also included.
• 0 = No automatic restart after overcurrent fault trip
• >0 = Number of automatic restarts after overcurrent trip and IGBT temperature faults.
10.355 (ID 723) Automatic Restart: Number of Tries after 4 mA Reference Trip
Location in the menu: P2.8.7 (Standard Application, Local/Remote Control Application, Multi-step Speed Control Application, PID
Control Application, Multi-purpose Control Application, Pump and Fan Control Application)
Use this parameter to set how many automatic restarts the AC drive can make during the set trial time after a 4 mA fault.
• 0 = No automatic restart after reference fault trip
• >0 = Number of automatic restarts after the analog current signal (4–20 mA) has returned to the normal level (>4 mA)
10.356 (ID 725) Automatic Restart: Number of Tries after External Fault Trip
Location in the menu: P2.8.9 (Standard Application, Local/Remote Control Application, Multi-step Speed Control Application, PID
Control Application, Multi-purpose Control Application, Pump and Fan Control Application)
Use this parameter to set how many automatic restarts the AC drive can make during the set trial time after an external fault.
• 0 = No automatic restart after External fault trip
• >0 = Number of automatic restarts after External fault trip
10.357 (ID 726) Automatic Restart: Number of Retries after Motor Temperature Fault Trip
Location in the menu: P2.8.8 (Standard Application, Local/Remote Control Application, Multi-step Speed Control Application, PID
Control Application, Multi-purpose Control Application, Pump and Fan Control Application)
Use this parameter to set how many automatic restarts the AC drive can make during the set trial time after a motor temperature
fault.
• 0 = No automatic restart after Motor temperature fault trip
• >0 = Number of automatic restarts after the motor temperature has returned to its normal level.
10.358 (ID 727) Response to Undervoltage Fault
Location in the menu: P2.7.5 (Standard Application, Local/Remote Control Application, Multi-step Speed Control Application, PID
Control Application, Multi-purpose Control Application, Pump and Fan Control Application)
Use this parameter to enable the automatic reset after an undervoltage fault.
For the undervoltage limits, see the User Manual of the product.
10.359 (ID 728) 4 mA Fault Frequency Reference
Location in the menu: P2.7.2 (Standard Application, Local/Remote Control Application, Multi-step Speed Control Application, PID
Control Application, Multi-purpose Control Application, Pump and Fan Control Application)
Use this parameter to set the frequency reference of the motor after a 4 mA fault when the response to the 4 mA fault is a warning.
If the value of parameter ID 700 is set to 3 and the 4 mA fault occurs, then the frequency reference to the motor is the value of this
parameter.
