How to fix an overheat issue on a Toshiba HX7+ ASD Controller?
To resolve an overheat issue on your Toshiba Controller, consider the following: * Reduce the operating temperature conditions. * Relocate the ASD away from heat sources. * Clear obstructions from the cooling fan vent. * Repair or replace the inoperative cooling fan. * Reconnect or replace the disconnected thermistor.
Why does my Toshiba Controller show Emergency Off?
If your Toshiba Controller shows an Emergency Off message, check for any Emergency Off commands issued via keypad or remotely.
What causes *OLI error on Toshiba HX7+ ASD?
The *OLI error on your Toshiba Controller can be caused by: * The carrier frequency being too high: Adjust the carrier frequency setting. * An excessive load: Reduce the load on the ASD. * Acceleration time being too short: Increase the acceleration time. * DC damping rate set too high: Adjust the DC damping rate. * The motor starting into a spinning load after a momentary power failure: Ensure the motor is completely stopped before restart. * The ASD being improperly matched to the application: Verify the ASD specifications match the application requirements.
How do I troubleshoot an OLM error on my Toshiba HX7+ ASD Controller?
To troubleshoot an OLM error on your Toshiba Controller, consider the following: * V/f parameter improperly set: Reconfigure the V/f parameter settings. * Motor is locked: Unlock the motor before operation. * Continuous operation at low speed: Adjust the application to prevent continuous low-speed operation. * The load is in excess of what the motor can deliver: Reduce the load on the motor.
What to do if Toshiba HX7+ ASD Controller displays an Overtorque error?
If your Toshiba Controller displays an Overtorque error, it could be due to: * ASD not correctly matched to the application: Ensure the ASD matches the application specifications. * F616 or F617 setting too low: Increase the settings for F616 or F617. * Obstructed load: Remove any obstructions from the load.
Why is my Toshiba HX7+ ASD Controller showing a DC Bus Undervoltage error?
A DC Bus Undervoltage error on your Toshiba Controller may indicate: * Low 3-phase input voltage: Check and restore 3-phase input voltage. * Defective control board: Replace the defective control board. * Excessive load on the power supply: Reduce the load on the power supply. * Undervoltage/Ridethrough settings require adjustment: Adjust the Undervoltage/Ridethrough settings.
What causes the *OLR error on a Toshiba HX7+ ASD?
The *OLR error on your Toshiba Controller can be triggered by: * Deceleration time being too short: Increase the deceleration time. * DBR configuration improperly set: Verify and correct the DBR configuration.
How to resolve Comm1 Error on Toshiba HX7+ ASD Controller?
To resolve a Comm1 Error on your Toshiba Controller: * Check the ASD programming. * Verify the communications settings. * Inspect and secure the connections.
