What to do if YASKAWA FSDrive-MV1000 Controller drive does not allow rotational auto-tuning?
If the YASKAWA Controller drive does not allow selection of rotational Auto-Tuning, the desired Auto-Tuning mode might not be available for the selected control mode. Check that A1-02 (Control Method Selection) is set to 0 (V/f control) and select the correct control mode at A1-02.
Why does the YASKAWA FSDrive-MV1000 drive frequency reference differ from the command?
If the drive frequency reference differs from the controller frequency reference command, the analog input gain and bias for the frequency reference input may be set to incorrect values. Check the gain and bias settings for the analog inputs used to set the frequency reference. Also, a frequency bias signal might be entered via analog input terminal L1, where the analog input setting (H3-02) is the sum of the individual input values. Finally, if PID control is enabled and unnecessary, disable it by setting b5-01 to 0.
How to fix YASKAWA FSDrive-MV1000 Controller motor rotating in opposite direction?
If the YASKAWA Controller motor rotates in the opposite direction from the Run command, the phase wiring between the drive and motor might be incorrect. Check the motor wiring and switch two motor cables (U, V, and W) to reverse the motor direction. Alternatively, the connection between the drive control circuit terminals (forward/reverse) and the forward/reverse signals of the control panel could be incorrect, so check the wiring of the control circuit and correct it. Also, verify that the forward direction for the motor is set up correctly by ensuring the drive’s output terminals (U, V, and W) and motor terminals (U, V, and W) are properly connected.
Why does YASKAWA Controller motor rotate in one direction only?
If the YASKAWA Controller motor rotates in one direction only, the drive might be prohibiting reverse rotation. To resolve this, set b1-04 to allow the motor to rotate in reverse.
Why YASKAWA FSDrive-MV1000 Controller motor has excessive oscillation?
If you observe excessive motor oscillation and erratic rotation in your YASKAWA Controller, it may be due to poor balance between motor phases. Check the drive input power voltage to ensure it provides stable power. Additionally, the hunting prevention function might be disabled. Enable Hunting Prevention (n1-01 = 1) and increase the AFR gain (n2-01) or the AFR time constant (n2-02).
What to do if YASKAWA Controller motor stalls during acceleration?
If the YASKAWA Controller motor stalls during acceleration, or with large loads, or if the acceleration time is too long, it could be due to several reasons. The torque limit might have been reached, or current suppression might be preventing acceleration. Reduce the load or increase motor capacity to resolve this. The load might be too heavy, so reduce it to keep the output current within the motor's rated current. Check the torque limit setting. The frequency reference might be too low, so check the maximum output frequency (E1-04) and increase it if necessary. Check if the acceleration time parameters (C1-01, C1-03, C1-05, C1-07) have been set too long. If using vector motor control, perform Auto-Tuning. Check the analog input terminal settings for incorrect frequency reference settings...
Why is my YASKAWA FSDrive-MV1000 motor too hot?
If the YASKAWA Controller motor is too hot, it could be due to several reasons. The load might be too heavy, so reduce the load, increase acceleration and deceleration times, check the motor protection values (L1-01, L1-02) and the motor rated current (E2-01), and consider increasing motor capacity. The air around the motor might be too hot, so check the ambient temperature and cool the area if needed. If operating in vector control mode, perform Auto-Tuning, calculate the motor value and reset the motor parameters, or change the motor control method to V/f Control (A1-02 = 0). Check the motor fan to make sure it hasn't stopped or become clogged. Note that when a motor is connected to the drive output terminals (U, V, W), a surge voltage is generated between the motor coils and drive switc...
