204 Warning, Alarm Diagnosis And Counter Measures
V560 Series High Performance Closed-Loop Vector Inverter User Manual
Possible causes Solutions
The wiring between frequency
inverter and motor is long
Shorten the output wiring as much as possible or install AC reactor.
Vibration is caused due to the
vibration system with lower
rigidity at the side of the load
Cancel the increasing of automatic torque, automatic energy-saving operation,
anti-overload control, current limit, torque limit and confirm whether the
vibration is disappeared.
5. THE MOTOR ROARS OR HAS ABNORMAL SOUND
Possible causes Solutions
The carrier is lower Increase the carrier frequency of the frequency inverter ([F1.1.13]).
The surrounding temperature of
the frequency inverter is higher
1. If the temperature exceeds 40℃, it shall strengthen Ventilation and reduce
temperature.
2. Reduce load and the temperature of frequency inverter (reduce upper
frequency limit for fan and pump ([F0.1.21])).
3. Select temperature associated adjustment function in carrier characteristics
([F1.1.14]).
Mechanical resonance
1. Operate the motor separately, find the reasons of resonance and improve
the characteristics at one side of the motor
2. Adjust hopping frequency ([F5.0.00]~[F5.0.05]) and avoid continuous
operation in the frequency area where resonance occurs.
Input phase failure
1. Inspect the connection between frequency inverter and motor.
2. Inspect whether the three-phase winding of the motor is faulty or damaged.
The motor parameters are set
improperly
Adjust motor speed closed loop PID parameter ([F8.2.25~F8.2.27]).
6. THE MOTOR DOES NOT ACCELERATE OR DECELERATE WITHIN THE SETTING
ACCELERATION AND DECELERATION TIME
Possible causes Solutions
Operate in the form of S
acceleration and deceleration
curve
1. Set the acceleration and deceleration characteristic parameter ([F1.0.00])
into linear acceleration and deceleration mode and observe the acceleration
and deceleration conditions.
2. Shorten the acceleration and deceleration time ([F1.0.03]~[F1.0.10]) and
observe the acceleration and deceleration conditions.
Current limit action, the
frequency rising is restricted
(in acceleration)
1. Increase the data of acceleration current limit level ([F1.4.39]) and strong
starting current limit level ([F1.4.40]).
2. Prolong acceleration time ([F1.0.03], [F1.0.05], [F1.0.07], and [F1.0.09]).
The motor has insufficient torque Increase torque and boost voltage ([F1.2.18]) and confirm whether it is started.
The acceleration and
deceleration of frequency is
limited due to the limitation of
torque
1. Reset the torque setting limit ([F8.3.47]) and maximum and minimum torque
limit value. ([F8.3.48]~[F8.3.51]).
2. Prolong acceleration and deceleration time ([F1.0.03]~[F1.0.10]).
Wrongly select the acceleration
and deceleration time
Inspect whether the selection signal for acceleration and deceleration time of
multifunctional input terminal ([F3.0.00]~[F3.0.08]) is correct or not.
