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: Set by parameter F02 (Deceleration 1).
= 001: Set by parameter C08.
C08 Stall prevention deceleration time: 00.1 ~ 999s
1.)
When the Acceleration time is set too low, the inverter could trip on Over Current (OC).
If the time can not be increased then trip prevention can be used. A trip prevention level has
to be programmed. When the inverter detects this level it holds the acceleration until the
current is below this set level and then continues with acceleration.
2.)
When the Deceleration time is set too low the inverter could trip on Over Voltage (OV).
If the time can not be increased then trip prevention can be used. A trip prevention level has
to be programmed. When the inverter detects this level it holds the deceleration until the
voltage is below this set level and then continues with deceleration.
3.)
The Inverter could trip (Stall) during run mode due to an impact load or sudden change 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 the inverter 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.)
When C09=000 and external run mode (F04=001), the inverter will auto start when the power
is supplied to the inverter and the run switch is ON.
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.)
We recommend that this mode stay disabled.
2.)
When C09=001 and external run mode (F04=001), the inverter will not auto start when power
is supplied and the RUN switch is ON.
Inverter display will blink "SP1" error message. It can only restart after the RUN switch was
turned off and ON again.
