C01 Acceleration stall-prevention:
=000: Enable Stall prevention during Acceleration.
=001: Disable Stall prevention during Acceleration.
C02 Acceleration stall-prevention level: 050% ~ 200%
C03 Deceleration stall-prevention:
= 000: Enable Stall prevention during deceleration.
= 001: Disable Stall prevention during deceleration.
C04 Deceleration stall-prevention level: 050% ~ 200%
C05 Run stall-prevention:
= 000: Enable Stall prevention in Run mode.
= 001: Disable Stall prevention in Run mode.
C06 Run stall-prevention level: 050% ~ 200%
C07 stall prevention time during run mode.
= 000: according to F02 ( Deceleration 1).
= 001: according to C08.
C08 Stall prevention deceleration time: 00.1 ~ 999s
1.) When the Acceleration time is set too short the inverter could trip on Over Current (OC).
If the time can not be increased then can use trip prevention, a trip prevention level has to be
programmed and when the inverter detects this level it holds the acceleration until the current
is below the set level then it continues with acceleration.
2.) When the Deceleration time is set too short the inverter could trip on Over Voltage (OV).
If the time can not be increased then can use trip prevention, a trip prevention level has to be
programmed and when the inverter detects this level it holds the deceleration until the voltage
is below the set level then it continues with deceleration.
3.) The Inverter could trip (Stall) during run mode due to an impact load or sudden changes of
the load.
Stall prevention in run mode will detect a programmed stall level ( C06) for a period of time
( C07) , if the level exceeds C06 , then invereter reduces its frequency ( speed) to provide
the required additional torque to overcome the stall,once this level is below the programmed
stall level then it ramps up to its normal running speed.
C09 Direct start on power up
000: Enable direct start on power up.
001: Disable direct start on power up.
Danger:
1.) C09=000 and external run mode (F04=001), the inverter will auto start as the power supplied to
the inverter and if the RUN switch is in ON position.
This feature should only be considered when all safety implications of its use have been
investigated. Risk assessment for maintenance, use of warning labels etc.
Our recommend option will be with this mode disabled.
2.) C09=001 and external run mode (F04=001), the inverter will not auto start as power supplied
and the RUN switch is in ON position.
Inverter display will blink with SP1 error message. It can only restart after the RUN switch
was turned off and ON again.
