Pr.60, Pr.61, Pr.62 – Over-torque Detection
Pr.60 Over-torque Detection Mode
Factory Setting d00
Units None
Settings d00 Over-torque Detection not enabled
d01 Over-torque Detection during constant speed operation.
Drive operation halted after over-torque detection.
d02 Over-torque Detection during constant speed operation.
Drive operation continues after over-torque detection.
d03 Over-torque Detection during operation.
Drive operation halted after over-torque detection.
d04 Over-torque Detection during operation.
Drive operation continues after over-torque detection.
This parameter determines the AC drive's operation after Over-torque is detected. Over-
torque Detection is based on the following: when the output current exceeds the Over-
torque Detection Level (Pr.61, factory preset value = 150%) and the Over-torque
Detection Time (Pr.62, factory setting = 0.1 second = 0.1 second, hysteresis fixed at
10%). The Multi-function PHC output 1 and 2 may be set to indicate over-torque
condition. (Refer to Pr.45 and 46).
Pr.61 Over-torque Detection Level
Factory Setting d150
Units 1%
Parameter value d00 - d200%
This parameter sets the Over-torque Detection Level in 1% increments. (The AC drive
rated current is defined to be 100%).
Pr.62 Over-torque Detection Time
Factory Setting d0.1 Sec
Units 0.1 Sec
Parameter value d0.1 - d10 Sec
This parameter sets the Over-torque Detection Time in units of 0.1 seconds.
