Description

Appears when torque command by the plug-in option is selected using Pr. 804 when no plug-in option is mounted or an AC power supply is connected to the R/L1, S/L2, T/L3 when the high power factor converter and power regeneration common converter connection setting (Pr.30=2) is selected.

Appears when output current exceeded the output current detection level set by the parameter. Appears when the resistor of the inrush current limit circuit overheated. Appears when a communication error occurred during the RS-485 communication with the RS-485 terminals. Appears when 30mA or more is input or a voltage (7.5V or more) is input with the terminal 2/4 set to current input. Indicates that the motor speed has exceeded the overspeed setting level

(Pr.374).

Stops the inverter output if the motor speed is increased or decreased under the influence of the load etc. during vector control and cannot be controlled in accordance with the speed command value.

Stops the inverter output if the encoder signal is shut off. Indicates that the difference between the position command and position feedback exceeded the reference. The inverter output is stopped when a sequence error occurs during use of the brake sequence function (Pr.278 to Pr.285). When the rotation command of the inverter differs from the actual motor rotation direction detected from the encoder, the inverter output is stopped. (detected only during tuning is performed in the "rotation mode" of offline auto tuning) Appears when an internal circuit error occurred. Appears when USB communication error occurred. The speed may not decelerate during low speed operation if the rotation direction of the speed command and the estimated speed differ when the rotation is changing from forward to reverse or from reverse to forward under real sensorless vector control. At this time, the inverter output is stopped if the rotation direction will not change, causing overload.

Notes:

*1. Resetting the inverter initializes the internal thermal integrated data of the electronic thermal relay function. *2. The error message shows an operational error. The inverter output is not shut off. *3. Warnings are messages given before major failures occur. The inverter output is not shut off. *4. Minor failure warns the operator of failures with output signals. The inverter output is not shut off. *5. When major failures occur, the protective functions are activated to shut off the inverter output and output the alarms. *6. The external thermal operates only when the OH signal is set in Pr.178 to Pr.189 (input terminal function selection). *7. Appears when the FR-A7AP (option) is fitted.
