PID feedback breaking detection
• Stop the inverter output detecting a breaking when the input current is allocated to the PID control feedback. (Select valid/invalid.)
Alarm relay output (for any fault)
• The inverter outputs a relay contact signal when the inverter issues an alarm and stops the inverter output.
• The alarm stop state is reset by pressing the PRG/RESET key or by the digital input signal RST.
Alarm relay output
(for any fault)
• The relay signal is output when the inverter stops upon an alarm.
• PRG/RESET key is used to reset the alarm stop state.
Light-alarm (warning)
Below items can be registered as minor errors
Alarm detection:
Overheating of the heatsink (OH1), External alarm (OH2), Inverter overheat (OH3), Overheating of braking resistor (dbH), Motor
overload (OL1 to OL4), Optional communication error (Er4), Option error (Er5), RS-485(port1) communication error (Er8),
Inconsistent speed (excessive speed deviation) (ErE), Positioning Control Error(Ero), RS-485 (port2) communication error (ErP),
Warning output:
DC fan lock detected, Overload early warning (for motor), heatsink overheat early warning, Life early warning (DC link bus capacitor,
electrolytic capacitor on printed circuit board, cooling fan), Reference command loss detected, PID warning output, Low torque
detected, Thermistor detection (PTC), Machine life (cumulative motor run time error), Machine life (number of startups error),
Stall prevention
• Operates when the inverter output goes beyond the instantaneous overcurrent limiting level, and avoids tripping, during
acceleration and constant speed operation.
Retry function
• When the motor is tripped and stopped, this function automatically resets the tripping state and restarts operation.
Surge protection
• The inverter is protected against surge voltage intruding between the main circuit power line and ground.
Command loss detected
• A loss (breaking, etc.) of the frequency command is detected to output an alarm and the operation is continued at the preset
frequency (set at a ratio to the frequency before detection).
Momentary power failure protection
• A protective function (inverter stoppage) is activated upon a momentary power failure for 15msec or longer.
•If restart upon momentary power failure is selected, the inverter restarts upon recovery of the voltage within the set time.
