8.2 ABNORMAL OPERATION WITHOUT PROMPTS AND THE
SOLUTIONS
1. THE MOTOR IS NOT ROTATED:
Possible causes Solutions
The operation command
channel is wrongly selected Switch the operation command channel into correct one via PANEL/REMOTE
key in operation panel or remote terminal
The operation command source
is wrongly selected
According to the need on the site, reset the selection of operation command
source ([F0.1.15]), control command 1([F0.3.33]) and control command 2
([F0.3.34])
The setting frequency is below
the starting frequency
1. Set the setting frequency to be above the starting frequency ([F0.4.39])
2. Inspect whether the frequency setting channel is normal or not, eliminate
possible analog input frequency setting failures and shuttle potentiometer
failures, etc.
3. Correctly connect the external terminals related to frequency setting
Other frequency command
sources with higher priority are
valid
According to the need on the site, reset the frequency (rotating speed) setting
priority ([F5.3.28])
The upper and lower frequency
limit is set improperly. Inspect the data of upper ([F0.1.21]) and lower ([F0.1.22]) frequency limit and
reset
The motor has insufficient torque
In V/F control mode:
x
Increase the torque of motor and boost voltage
x
Adjust V/F curve
In SVC/VC control mode:
x
Re-measure the parameters of motor ([F2.2.53])
x
Adjust vector mode and start pre-excitation time ([F2.2.52])
2. THE MOTOR IS ROTATING BUT THE SPEED CAN NOT BE INCREASED:
Possible causes Solutions
The setting value of maximum
output frequency is too low.
Increase the value of maximum output frequency ([F0.1.20]).
The setting value of upper
frequency limit is too low.
1. Increase the data of upper frequency limit ([F0.1.21]).
2. Increase the maximum value of frequency setting channel 1([F0.2.28]) and 2
([F0.2.31]).
The set frequency is too low.
Inspect whether the setting of selection of frequency setting channel ([F0.1.16])
is correct or not; the set frequency value is lower or the frequency setting
channel is faulty.
