It may also be activated by a surge voltage generated in the power supply system. Check for sudden speed reduction. • Increase the deceleration time. (Set the deceleration time which matches the inertia moment of the load.) • Decrease the braking duty. • Use the brake unit or high power factor converter (FR-HC) as required. Motor overload shut-off (electronic overcurrent protection) The electronic overcurrent protection in the inverter detects motor overheat due to overload or reduced cooling capability during constant-speed operation to stop the inverter output.When a multi-pole motor or two or more motors are run, provide a thermal relay in the output side of the inverter. Check the motor for use under overload. • Reduce the load weight. • For the constant-torque motor, change the Pr. 71 setting to the constant-torque motor setting. Inverter overload shut- off (electronic overcurrent protection) If a current of more than 150% of the rated output current flows and overcurrent shut-off does not occur (200% or less) inverse-time characteristics cause the electronic overcurrent protection to be activated to stop the inverter output in order to protect the output transistors. Note: Resetting the inverter initializes the internal heat integrating data of the electronic overcurrent protection. Check the motor for use under overload. Reduce the load weight. Fin overheat If the cooling fin overheats, the overheat sensor is actuated to stop the inverter output. • Check for too high ambient temperature. • Check for cooling fin clogging. Set the ambient temperature to within the specifications.

© Copyright, Alliance Laundry Systems LLC – DO NOT COPY or TRANSMIT Brake transistor alarm detection If a brake transistor fault occurs due to excessively large regenerative energy from the motor, for example, that fault is detected to stop the inverter output. In this case, the inverter power must be switched off immediately. Note: This function is activated only when the optional brake resistor is connected. Check for improper braking duty. • Change the inverter. • Please contact your sales representative. Output side ground fault overcurrent protection This function stops the inverter output if a ground fault overcurrent flows due to a ground fault which occurred in the inverter's output (load) side. Use Pr. 249 "ground fault detection at start” to set whether the protective function is to be activated or not. (In the 400V class, the protective function is always active.) Check for a ground fault in the motor and connection cable. Remedy the ground fault portion. External thermal relay operation If the external thermal relay designed for motor overheat protection or the internally mounted temperature relay in the motor switches on (contacts open), the inverter output is stopped. If the relay contacts are reset automatically, the inverter will not restart unless it is reset. Note: This function is activated only when OH has been set to any of Pr. 180 to Pr. 183 (input terminal function selection). • Check for motor overheating. • Check that the value of 7 (OH signal) is set correctly in any of Pr. 180 to Pr. 183 (input terminal function selection). Reduce the load and operating duty. Stall prevention The running frequency has fallen to 0 by stall prevention activated. (OL while stall prevention is being activated.) Check the motor for use under overload. Reduce the load weight. Option alarm Stops the inverter output if the inverter station is disconnected from the system in the NET mode. Also stops the inverter output if the dedicated option used in the inverter results in setting error or connection (connector) fault. Note: Only when the FR-E5NC is fitted to the three-phase 400V power input model. Check that the plug-in option connector is plugged securely. • Connect the plug-in option securely. • Please contact your sales representative. Parameter storage device alarm A fault occurred in parameters stored (example: E2PROM fault). Check for too many number of parameter write times. Please contact your sales representative. Parameter unit disconnection This function stops the inverter output if communication between the inverter and PU is suspended, e.g. the PU is disconnected, when "2", "3", "16" or "17" was set in Pr. 75. This function stops the inverter output if the number of successive communication errors is greater than the number of permissible retries when the Pr. 121 value is "9999" for RS-485 communication from the PU connector. • Check for loose fitting of the control panel (FR-PA02-o2) or FR-PU04. • Check the Pr. 75 setting. Fit the control panel (FR-PA02-o2) and FR-PU04 securely. Retry count exceeded If operation cannot be resumed properly within the number of retries set, this function stops the inverter output. Find the cause of alarm occurrence. Eliminate the cause of the error preceding this error indication. CPU error If the arithmetic operation of the built-in CPU does not end within a predetermined period, the inverter self-determines it as an alarm and stops the output. Please contact your sales representative. CPU error This function stops the inverter output if a communication error occurs in the built-in CPU. (400V class only) Please contact your sales representative. No Motor Operation With AC Drive Fault(continued) Operation Panel Indication Name Description and NOTES Check point Corrective action

© Copyright, Alliance Laundry Systems LLC – DO NOT COPY or TRANSMIT Output phase failure protection This function stops the inverter output if one of the three phases (U, V, W) on the inverter's output side (load side) results in open phase. • Check the wiring (Check the motor for a fault.) • Check that the capacity of the used motor is not smaller than the inverter capacity. • Wire the cables properly. • Check the setting of Pr. 251 "output phase failure protection selection". Fan fault For the inverter which contains a cooling fan, FN appears on the operation panel when the cooling fan stops due to a fault or operates differently from the setting of Pr. 244 "cooling fan operation selection". Check the cooling fan for a fault. Change the fan. Stall prevention (overcurrent) During acceleration—If a current of more than 150% of the rated inverter current flows in the motor, this function stops the increase in frequency until the overload current reduces to prevent the inverter from resulting in overcurrent shut-off. When the overload current has reduced below 150%, this function increases the frequency again. During constant-speed operation—If a current of more than 150% of the rated inverter current flows in the motor, this function lowers the frequency until the overload current reduces to prevent overcurrent shut-off. When the ~ overload current has reduced below 150%, this function increases the frequency up to the set value. During deceleration—If a current of more than 150% of the rated inverter current flows in the motor, this function stops the decrease in frequency until the overload current reduces to prevent the inverter from resulting in overcurrent shut-off. When the overload current has reduced below 150%, this function decreases the frequency again. Check the motor for use under overload. The acceleration/ deceleration time may change. Increase the stall prevention operation level with Pr. 22 "stall prevention operation level", or disable stall prevention with Pr. 156 "stall prevention operation selection". Note: The stall prevention operation current can be set as desired. It is factory-set to 150%. Stall prevention (overvoltage) During deceleration—If the regenerative energy of the motor increases too much to exceed the brake capability, this function stops the decrease in frequency to prevent overvoltage shutoff. As soon as the regenerative energy has reduced, deceleration resumes. • Check for sudden speed reduction. • The deceleration time may change. Increase the deceleration time using Pr. 8 "deceleration time" PU stop A stop made by pressing the key of the PU has been set in Pr. 75 "PU stop selection". • Check for a stop made by pressing the key of the operation panel during external operation. • Perform opeartion correctly. This alarm appears if: • The RES signal is on; • You attempted to set any parameter value in the external operation mode; • You attempted to change the operation mode during operation; • You attempted to set any parameter value outside its setting range. • You attempted to set any parameter value during operation (while signal STF or STR is ON). • You attempted to set any parameter value while parameter write is being inhibited in Pr. 77 "parameter write inhibit selection". • Perform operation correctly.
