Why CHINSC ELECTRIC 200 shows over-voltage in constant speed operation?
If over-voltage happens in constant speed operation, it can be caused by abnormal change of input voltage (install input reactor) or too big load inertia (use suitable dynamic braking group).
What causes over-current during deceleration in CHINSC ELECTRIC DC Drives?
Over-current during deceleration can occur because of: too short Dec time (prolong the Dec time), low AC supply voltage (use suitable dynamic braking kit), or the drive power being too small (select a higher power drive).
How to resolve over-current in constant speed operation in CHINSC ELECTRIC DC Drives?
If there is over-current in constant speed operation, possible causes include: sudden change of load or abnormal load (check the load or reduce the sudden change of load), low AC supply voltage (check the AC input power supply), or the drive power being too small (select a higher power drive).
What causes over-voltage during deceleration in CHINSC ELECTRIC 200?
If over-voltage occurs during deceleration, the causes might be: too short Dec time (prolong the Dec time), too big load inertia (use big dynamic braking group), or abnormal input voltage (check the AC supply voltage).
Why is there an over-voltage during acceleration in CHINSC ELECTRIC DC Drives?
Over-voltage during acceleration may be caused by: abnormal input voltage (check the input power supply), or the rotating motor re-starting after the drive stops instantly (avoid re-start after the drive stops instantly).
What to do if CHINSC ELECTRIC 200 shows braking kit fault?
If there is a braking kit fault, it can be caused by: brake line fails or brake pipe is damaged (check the brake kit, update brake pipe), or the external braking resistance is small (increase braking resistor).
What does EEPROM R/W fault mean in CHINSC ELECTRIC DC Drives?
If there is an EEPROM R/W fault, it indicates: R/W fault of control parameters (press STOP/RST to reset and seek service) or EEPROM damaged (seek service).
What to do if CHINSC ELECTRIC DC Drives shows PID feedback disconnected fault?
If a PID feedback disconnected fault occurs, it could be due to: PID feedback disconnected (check PID feedback signal line) or the source of PID feedback disappears (check the PID feedback source).
What does it mean if CHINSC ELECTRIC DC Drives shows output phase failure?
Output phase failure means U, V, W output loss (or the 3-phase loads are serious asymmetry). Check the drive’s output wiring, the cable and the motor.
What causes IGBT module’s heatsink to overheat in CHINSC ELECTRIC 200?
If the IGBT module’s heatsink overheats, potential causes include: obstructed vent or non-working fan (clean the vent or replace the fan), over-temperature (lower the ambient temperature), loose wires or connectors of the control board (check and rewiring), damaged auxiliary power supply or IGBT driving voltage is too low (seek service), short-circuit of IGBT bridge (seek service), or abnormal control board (seek service).
