Multi-function digital outputs (R1A-R1C, R2A-R2C) can be set to an over torque detection condition by setting
parameters 03-11 or 03-12 to 12. Refer to the following figure.
Parameter 08-13 selects over-torque detection function. An over-torque condition is detected when the output current
/ torque rises above the level set in parameter 08-15 (Over-torque detection level) for the time specified in parameter
08-16 (Over-torque detection time).
08-13=0
: Over-torque detection is disabled.
08-13=1
: Over-torque detection is enabled when the output frequency reaches the set frequency.
08-13=2
: Over-torque detection is enabled during run mode.
Parameter 08-14 selects the way the AC Drive acts when an over-torque condition is detected.
08-14=0
: When an over-torque condition is detected the AC Drive displays an over-torque detection fault and the
motor decelerates to a stop.
08-14=1
: When an over-torque condition is detected the AC Drive displays an over-torque detection alarm and
continues to run.
08-14=2:
When an over-torque condition is detected the AC Drive displays an over-torque detection fault and the
motor coasts to a stop
