P249 PID Reference Ramp Up Time
P249
Range
0 ÷ 32700
Function of P251
Default
0
0 s
Level
ENGINEERING
Address
849
Function
This parameter defines the ramp up time of the PID regulator reference from 0%
to the max. allowable absolute value (max. {|P245|,|P246|}).
P250 PID Reference Ramp Down Time
P250
Range
0 ÷ 32700
Function of P251
Default
0
0 s
Level
ENGINEERING
Address
850
Function
This parameter defines the ramp down time of the PID regulator reference, from
max. allowable value (max. {|P245|,|P246|}) to 0%.
P251 Unit of measure of PID Ramp
P251 Range
0 ÷ 3
0: 0.01 s
1: 0.1 s
2: 1.0 s
3: 10.0 s
Default
1
1: 0.10 s

Address
851
Function
This parameter defines the unit of measure for the PID reference ramp times.
It defines the unit of measure for the time of the third ramp of the PID reference
P249 and P250, so that the allowable range becomes 0s – 327000s.
Example:

NOTE
Factory-
setting: the PID reference ramp is zero; if a given ramp time is set up, the ramp will
be rounded off (50% at the beginning and at the end of the ramp). See parameters P252
and P253.
