Chapter 4 Explanation of Functions 4.2.64 Over-torque signal (OTQ) The inverter outputs the over-torque signal when it detects that the estimated motor output torque exceeds the specified level. To enable this function, assign function "07" (OTQ: over-torque signal) to an intelligent output terminal. This function is effective only when the V/F characteristic curve selection selected with function "A044" or "A244" is the sensorless vector control, 0Hz-range sensorless vector control, or vector control with sensor. With any other V/F characteristic curve selection, the output of the OTQ signal is unpredictable. When using the inverter for a lift, use the OTQ signal as the trigger to stop braking. Use the frequency-arrival signal as the trigger to start braking.

(%) regenerating) level setting during forward regeneration operation 4.2.65 Alarm code output function (AC0 to AC3) The alarm code output function allows you to make the inverter output a 3- or 4-bit code signal as the trip factor when it has tripped.

The following table lists the alarm codes that can be output: Intelligent output terminals When "4 bits" is selected When "3 bits" is selected 14 13 12 11 AC3 AC2 AC1 AC0 Factor code Cause of tripping Factor code Cause of tripping 0 0 0 0 Normal Normal operation Normal Normal 0 0 0 1 E01 to E03,E04 Overcurrent protection E01 to E03, E04 Overcurrent protection Overload protection Overload protection 0 0 1 0 E05, E38 Low-speed overload protection E05 Low-speed overload protection 0 0 1 1 E07, E15 Overvoltage/input Overvoltage/input E07, E15 overvoltage protection overvoltage protection 0 1 0 0 E09 Undervoltage protection E09 Undervoltage protection 0 1 0 1 E16 Instantaneous power failure Instantaneous power E16 protection failure protection 0 1 1 0 E30 IGBT error E30 IGBT error 0 1 1 1 E06 Braking resistor overload protection - Other error 1 0 0 0 EEPROM, CPU, GA E08, E11, E23 communication, or main E25 circuit error - - 1 0 0 1 E10 CT error - - 1 0 1 0 External trip, USP error, E12, E13, E35, thermistor error, or braking E36 error - - 1 0 1 1 E14 Ground-fault protection - - Invalid instruction in easy sequence 1 1 0 0 Nesting error in easy E43, E44, E45 sequence Easy sequence execution command error - - 4 - 66

This function applies to all output signals, except to logical operation results (LOG1 to LOG6). Three types of operators (AND, OR, and XOR) are selectable. Output signal 1 Output signal 2 LOGx (AND) LOGx (OR) LOGx (XOR) Related code C021 to C025: Terminal [11] to [15] functions C026: Alarm relay terminal function C142: Logical output signal 1 selection 1 C143: Logical output signal 1 selection 2 C144: Logical output signal 1 operator selection C145: Logical output signal 2 selection 1 C146: Logical output signal 2 selection 2 C147: Logical output signal 2 operator selection C148: Logical output signal 3 selection 1 C149: Logical output signal 3 selection 2 C150: Logical output signal 3 operator selection C151: Logical output signal 4 selection 1 C152: Logical output signal 4 selection 2 C153: Logical output signal 4 operator selection C154: Logical output signal 5 selection 1 C155: Logical output signal 5 selection 2 C156: Logical output signal 5 operator selection C157: Logical output signal 6 selection 1 C158: Logical output signal 6 selection 2 C159: Logical output signal 6 operator selection The necessary parameters depend on the logical output signal to be operated.
