What to do if Selec VFD DC Drives show an overvoltage fault?
If your Selec DC Drive displays an overvoltage fault, it could be due to several reasons. First, verify that the input voltage is within the acceptable range. Second, if you are experiencing rapid deceleration, try increasing the deceleration time. Finally, for loads with heavy inertia, consider using a dynamic braking resistor.
What causes an overheat fault in Selec VFD DC Drives and how to fix it?
An overheat fault in Selec DC Drives can stem from a few causes. High ambient temperature, obstructions to ventilation, a malfunctioning fan, or an unclean heatsink are potential culprits. Additionally, excessive load on the motor can lead to overheating. To resolve this: * Ensure proper ventilation and check the fan. * Clean any dust or debris from the heat sink. * Reduce the load on the motor or reduce the carrier frequency.
What causes Selec VFD to short-circuit and what should I do?
A short-circuit in Selec DC Drives can be caused by several factors. It may be due to similar reasons as an over-current fault, a short circuit of power terminals, or damage to the power module. You should check the condition of wires connected to the power terminals.
What to do if Selec DC Drives show an over-current fault?
If your Selec DC Drive is showing an over-current fault, consider these potential causes and solutions: there may be a mismatch of capacity, so select an appropriately sized VFD. Check the input voltage and wirings. If acceleration or deceleration is too rapid, increase those times. Also, detect and reduce heavy load fluctuations.
What causes an overload fault in Selec DC Drives?
An overload fault in Selec DC Drives can occur due to reasons similar to an over-current fault. Additionally, incorrect V/f settings or an excessive load on the motor might be the cause. Recheck and select appropriate settings for V/f control and reduce the load on the motor.
Why Selec VFD DC Drives show an under-voltage fault and how to fix it?
An under-voltage fault in Selec DC Drives is caused by the input voltage. To resolve this, check that the input voltage is within the permissible range.
What causes an external fault in Selec VFD DC Drives?
An external fault in Selec DC Drives is caused by receiving an external fault signal from input terminals. To address this, check the input terminal settings to eliminate false alarms. If a terminal is set to trigger an external fault, verify its status.
