C (Advanced) Parameter Function Descriptions
C00 Reverse run
000: Reverse enable
001: Reverse disable
When F04=000 (Run signal source) and C00=001, F03 (motor direction) is disabled and the inverter is
set to run forward.
When F04=001 or 002 (Run signal source) and C00=001, the reverse command is disabled.
C01 Acceleration stall-prevention mode
000: Enable stall prevention during acceleration
001: Disable stall prevention during acceleration
C02 Acceleration stall-prevention mode
level (%)
050% - 200%
C03 Deceleration stall-prevention mode
000: Enable stall prevention during deceleration
001: Disable stall prevention during deceleration
C04 Deceleration stall-prevention mode
level (%)
050% - 200%
C05 Run stall-prevention mode
000: Enable stall prevention in run mode
001: Disable stall prevention in run mode
C06 Run stall-prevention mode level (%)
050% - 200%
C07 Stall prevention time during run mode
0 0 0 : S e t b y p a r a m e t e r F 0 2 ( D e c e l e ra t i o n 1 )
0 0 1 : S e t b y p a r a m e t e r C 0 8
C08 Stall prevention deceleration
time (sec.)
0 0 . 1 - 9 9 9 s
1.) When the acceleration time is set too low, the inverter may trip on Overcurrent (OC).
If the acceleration time can not be increased, then stall prevention can be used. The stall
prevention level C02 must be programmed. When the inverter detects this level it stops the
acceleration until the output 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 Overvoltage (OV).
If the deceleration time can not be increased, then stall prevention can be used. The stall
prevention level C04 must be programmed. When the inverter detects this level it holds the
deceleration until the DC bus voltage is below this set level, and then continues with deceleration.
3.) The Inverter could trip (Stall) at set frequency 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 to provide the required
additional torque to overcome the stall. Once this level is below the programmed stall level, the
inverter 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
1.) When C09=000 and external run mode (F04=001) is enabled, the inverter will auto start when
the power is supplied to the inverter and the run switch is ON.
Danger
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 this mode to be disabled.
