What to do if CHINSC ELECTRIC SVF-G7 show PID feedback bigger fault?
If your CHINSC ELECTRIC DC Drives show PID feedback bigger fault, check PID feedback signal wire, if the PI parameter setting too bigger.
What causes over-current in CHINSC ELECTRIC SVF-G7 during constant speed operation?
Over-current during constant speed operation in CHINSC ELECTRIC DC Drives can be caused by a sudden change of load or an abnormal load. Check the load or reduce the sudden change of load. It may also be due to a low AC supply voltage, so check the AC input power supply. If the drive power is too small, select a high power drive.
How to fix over-voltage during deceleration in CHINSC ELECTRIC SVF-G7?
If you are experiencing over-voltage during deceleration with your CHINSC ELECTRIC DC Drives, it could be due to a too short Dec time. Try prolonging the Dec time. Another potential cause is too big load inertia, in which case you should use a big dynamic braking kit. Also, check the AC supply voltage, as an abnormal input voltage could be the reason.
What causes CHINSC ELECTRIC DC Drives motor to overload?
A CHINSC ELECTRIC DC Drives motor can overload due to several reasons. A low AC supply voltage could be the cause, so check the AC supply voltage. It may also be due to an improper motor’s rated current, so modify the motor’s rated current. If the load increases suddenly, check the load and adjust the value of torque boost. Finally, the drive's and motor's powers might not match, so use a suitable motor.
What causes CHINSC ELECTRIC SVF-G7 to show IGBT module’s heatsink overheat?
If the IGBT module’s heatsink in your CHINSC ELECTRIC DC Drives is overheating, it could be due to several factors. The vent might be obstructed, or the fan may not be working, so clean the vent or replace the fan. Over-temperature can also cause this issue, so lower the ambient temperature. Check and re-wire any loose wires or connectors of the control board. If the auxiliary power supply is damaged or the IGBT driving voltage is too low, or if there is a short-circuit of the IGBT bridge, or the control board is abnormal seek service.
What does it mean if my CHINSC ELECTRIC DC Drives show external equipment fails?
Check the input of the external device.
What to do if CHINSC ELECTRIC SVF-G7 show PID feedback disconnected fault?
If your CHINSC ELECTRIC DC Drives show PID feedback disconnected fault, check PID feedback signal line, as PID feedback may be disconnected. Check the PID feedback source, as the source of PID feedback may disappears.
What to do if CHINSC ELECTRIC DC Drives show braking kit fault?
If your CHINSC ELECTRIC DC Drives show braking kit fault, check the brake kit and update brake pipe, as brake line may fail or brake pipe may be damaged. Increase braking resistor, as the external braking resistance may be small.
What does it mean if my CHINSC ELECTRIC DC Drives show rectifier’s heatsink overheat?
If the rectifier’s heatsink in your CHINSC ELECTRIC DC Drives is overheating, this could be due to instantaneous over-current. Refer to E004~E006. It might also indicate a short-circuit among the 3-phase output or a line-to-ground short circuit, in which case you should rewire.
What to do if CHINSC ELECTRIC DC Drives show DC Bus under-voltage?
If your CHINSC ELECTRIC DC Drives show DC Bus under-voltage, check the AC supply voltage, as the cause is likely a low AC supply voltage.
