Specification of high-performance vector convertor
P9-05
P9-06
Overcurrent stall protection current
In the inverter deceleration process, when the output current exceeds the overcurrent stall protection current, the inverter
stops deceleration process is maintained at the current operating frequency, output current drops and then continue to be
deceleration.
Over-flow speed gain is used to adjust the acceleration and deceleration process, the drive capacity in suppressing the flow.
The bigger the value, the stronger the capacity is. In the stream without happened next, the gain is set as small as possible.
For small inertia load, over-current stall gain should be small, otherwise the system dynamic response slow. For large inertia
loads, this value should be large, otherwise the suppression ineffective, overcurrent fault may occur.
0 when the stall gain is set to cancel the stall function.
Power-to-ground short circuit protection
P9-07
Select the inverter at power, detecting whether the motor is shorted to ground.
If this function is active, the UVW side of the inverter after power-output voltage will be a period of time.
P9-09
When the inverter selects fault auto reset, used to set the number of auto reset. More than this number of times the drive
remains a fault condition.
P9-10
If the drive is set up automatic fault reset function, then during automatic fault reset, fault DO whether action can be set by
P9-10.
P9-11
Since the inverter fault alarm, automatic fault reset time to wait between.
P9-12
Select whether the input phase loss protection.
Inverter 18.5kW G-type machines and more power, have input phase protection, 18.5kW P-type machine less power.
Regardless of P9-12 is set to 0 or 1 have no input phase loss protection.
