Parameters and firmware blocks
110
25.08 SHAPE TIME DEC2 FW block: SPEED REF RAMP (see above)
Selects the shape of the deceleration ramp at the end of the deceleration. See parameter 25.05
SHAPE TIME ACC1 .
0…1000 s Ramp shape at end of deceleration.
25.09 ACC TIME JOGGING FW block: SPEED REF RAMP (see above)
Defines the acceleration time for the jogging function i.e. the time required for the speed to change
from zero to the speed value defined by parameter
25.02 SPEED SCALING .
0…1800 s Acceleration time for jogging.
25.10 DEC TIME JOGGING FW block: SPEED REF RAMP (see above)
Defines the deceleration time for the jogging function i.e. the time required for the speed to change
from the speed value defined by parameter
25.02 SPEED SCALING to zero.
0…1800 s Deceleration time for jogging.
25.11 EM STOP TIME FW block: SPEED REF RAMP (see above)
Defines the time inside which the drive is stopped if an emergency stop OFF3 is activated (i.e. the
time required for the speed to change from the speed value defined by parameter
25.02 SPEED
SCALING to zero). Emergency stop activation source is selected by parameter 10.10 EM STOP
OFF3 . Emergency stop can also be activated through fieldbus ( 2.12 FBA MAIN CW ).
Emergency stop OFF1 uses the active ramp time.
0…1800 s Emergency stop OFF3 deceleration time.
25.12 SPEEDREF BAL FW block: SPEED REF RAMP (see above)
Defines the reference for the speed ramp balancing, i.e. the output of the speed reference ramp
firmware block is forced to a defined value.
The source for the balancing enable signal is selected by parameter
25.13 SPEEDREF BAL .
-30000…30000 rpm Speed ramp balancing reference.
25.13 SPEEDREF BAL ENA FW block: SPEED REF RAMP (see above)
Selects the source for enabling the speed ramp balancing. See parameter 25.12 SPEEDREF BAL .
1 = Speed ramp balancing enabled.
