What causes Virtual Linear Pump No Flow on a Toshiba GX9 Controller?
If your Toshiba Controller shows a Virtual Linear Pump No Flow error, it may be due to: * Pump prime required. * Feed water loss. * Output valve is closed. * System may be set to Trip or Alarm for this condition at F935.
Why does my Toshiba GX9 show an Over-Current error?
If the Toshiba Controller shows an Over-Current error, it could be due to several reasons: * A defective IGBT (U, V, or W). * Incorrectly connected ASD output to the motor. * ASD output phase-to-phase short. * The ASD starting into a spinning motor. * A jammed motor or machine. * Mechanical brake engaged during ASD start or run. * Accel/Decel time being too short. * Voltage Boost setting being too high. * Load fluctuations. * ASD operating at an elevated temperature.
What causes Braking Resistor Overload in a Toshiba Controller?
If your Toshiba Controller displays a Braking Resistor Overload, it could be due to: * Deceleration time being too short. * DBR configuration improperly set.
What causes Earth Fault on Toshiba Controller?
If your Toshiba Controller shows an Earth Fault, this may be due to: * Ground fault at the motor. * Ground fault at the output of the ASD. * Current leakage to Earth Ground.
Why is my Toshiba GX9 Over-Heat During Deceleration?
If your Toshiba Controller is experiencing Over-Heat During Deceleration, possible causes include: * Cooling fan inoperative. * Ventilation openings are obstructed. * Internal thermistor is disconnected. * Deceleration time is too short. * DC Injection current is too high. * ASD or the motor is improperly matched to the application.
What causes Over-Current During Deceleration on a Toshiba GX9?
If your Toshiba Controller displays an Over-Current During Deceleration error, it could be due to: * Phase-to-phase short (U, V, or W). * Deceleration time being too short. * Motor/machine jammed. * Mechanical brake engaged while the ASD is running. * ASD current exceeding specified limits during deceleration.
Why does my Toshiba Controller show Over-Heat During Acceleration?
If your Toshiba Controller is experiencing Over-Heat During Acceleration, it could be due to: * Cooling fan inoperative. * Ventilation openings are obstructed. * Internal thermistor is disconnected. * Acceleration time is too short. * Improper V/f setting. * ASD or the motor is improperly matched to the application.
What causes Excessive Torque in a Toshiba GX9 Controller?
If you're experiencing Excessive Torque with your Toshiba Controller, it could be because: * The ASD is not correctly matched to the application. * The F616 or F617 setting is too low. * There is an obstructed load.
Why does Toshiba Controller show Over-Current During Acceleration?
If your Toshiba Controller shows an Over-Current During Acceleration error, it might be caused by: * Improper V/f setting. * Restart from a momentary power outage. * The ASD starting into a rotating motor. * ASD/Motor not properly matched. * Phase-to-phase short (U, V, or W). * Accel time too short. * Voltage Boost setting too high. * Motor/machine jammed. * Mechanical brake engaged while the ASD is running. * ASD current exceeding specified limits during acceleration.
What causes Motor Overload on my Toshiba GX9 Controller?
If your Toshiba Controller shows a Motor Overload error, it could be due to: * Improper V/f setting. * The motor being locked. * Continuous operation at low speed. * Startup frequency setting adjustment required.
