d1-12
Current limitation mode
Range: 0~5
Factory default: 1
0: Disabled
1: Set by d1-13
2: Set by AI1
3: Set by AI2
4: Set by EAI
Drive output current is limited by analog input in the range of " 0~200% x rated current of drive".
5: Set by X6/DI
Drive output current is limited by X6/DI pulse input in the range of "0~200% x rated current of
drive".
When a non-zero value is set by d1-12, the current limitation is enabled. When output current
rises dramatically because of sharp change of load, instant adjustment of output frequency will
keep the output frequency below the set limitation. When the load is reduced, output frequency
will recover promptly. If the setting speed or motor load change dramatically, this function can
effectively reduce over-current fault.
When current limitation is enabled, the output frequency at constant speed may change at
times and the Accel/Decel time may probably be automatically prolonged. Therefore, this
function should not be used where output frequency or Accel/Decel time is not allowed to
change.
d1-13
Digital setting of current
limit value
Range: 20.0%~200.0%
Factory default:
160.0%
When d1-12 is set to "1: set by d1-13", the drive keeps output current less than this current limit
value through instantaneous adjustment of output frequency. 100% current limit value
corresponds to rated current of the drive. If this parameter value is set to a relatively big one, it
will increase the chances of over-current. If this parameter value is set to a relatively small one,
it will affect the loaded capability of the drive.
d1-14
Current limit coeff on flux
weakening
Range: 0.001~1.000
Factory default:
0.500
When the drive runs at the frequency higher than rated frequency of motor, Accel/Decel
characteristic and output torque can be effectively improved by setting this parameter
appropriately.
d1-15
Energy saving percentage
Range: 0%~40.0%
Factory default:
0.0%
During no-load or light-load application, load current is detected so as to appropriately reduce
output voltage, reducing the copper loss and iron loss of motor with the purpose of energy
saving. The larger the energy-saving percentage is, the better the energy-saving effect will be,
