Fn_78: Over Torque Detection Level: 30 - 200 %
Fn_79: Over Torque Detection Time: 0 - 25 sec
Note:
1. Definition of the over torque feature: the output current (rated current is 100%) remains above
over torque detection level (Fn_78) during over torque detection time (Fn_79).
2. (Fn_77) is set to (x0xx) When over torque occurs, the T-verter continues running and display
the blinking “OL3” light until the output current is lower than the (Fn_78) setting.
(Fn_77) is set to (x1xx) When over torque occurs, the T-verters base blocks immediately and
the display blinks “OL3”. To re-start the drive, it is necessary to press RESET key.
3. When (Fn_61) (Fn_62) or (Fn63) (multi-function output terminal control) is set to 05, the
multi-function output provides an over torque detection signal. The over torque detection
output signal is available only if (Fn_77) is set to (xxx1)
Fn_80: S-Curve Set-up: Time (1) Acceleration & Deceleration: 0 to 4 Sec.
Fn_81: S-Curve Set-up: Time (1) or (2) Acceleration & Deceleration: 0 to 4 Sec.
Formula for Calculating Acceleration and Deceleration Time.
Accel. Time = (Fn_01) or (Fn_49) X
Decel. Time = (Fn_02) or (Fn_50) X
