Over-Current Stall
Prevention during
Operation
Range: Default: 150%
00: disable
20 to 200%: enable
Unit: 1%
During steady-state operation with the motor load rapidly
increasing, the AC drive output current may exceed the limit
specified in 70.03. When this occurs, the output frequency will
decrease to prevent an Over Current Fault. The drive will
accelerate back to the command frequency only when the
output current drops below the level specified by 70.03.
70.04
Over-Torque
Detection Mode(OL2)
Range: Default: 00
00 Over-Torque detection disabled
01 Over-Torque detection enabled during constant speed
operation, and operation halted after Over-Torque
Detection
02 Over-Torque detection enabled during constant speed
operation, and operation continues after Over-Torque
Detection
03 Over-Torque detection enabled during operation, and
