P0105 – 1st/2nd Ramp Selection
Adjustable Range:
0 = 1st Ramp
Factory Setting:
2
1 = 2nd Ramp
2 = DIx
3 = Serial/USB
4 = Anybus-CC
5 = SoftPLC
Properties:
CFG1
Groups of
01 PARAMETER GROUPS
...
Access via HMI:
21 Ramps
Description:
It defines the origin source of the command that will select between the first and second Ramp.
Notes:
■
The option “0”(1st Ramp) means the converter will always follow the values set in P0100 and P0101;
■
The option “1”(2nd Ramp) means the converter will always follow the values set in P0102 and P0103;
■
You can monitor the ramp setting used in a certain moment in parameter P0680 (Logical Status).
7.3.3
Speed References [22]
This parameter group allows setting the reference values for the motor speed and for the JOG, JOG+ and JOG-
functions. It is also possible to define if the reference value will be maintained when the converter is shut down.
P0120 – Speed Reference Backup
Adjustable Range:
0 = Inactive
Factory Setting:
1
1 = Active
Properties:
Groups of
01 PARAMETER GROUPS
...
Access via HMI:
22 Speed References
...............
Description:
This parameter defines if the speed reference backup function is active or inactive.
If P0120 = Inactive, the converter will not save the speed reference value when it is shut down. Thus, when the
converter is powered up again, the speed reference value will become the minimum speed limit value (P0133).
This backup function applies only to the references via keypad (HMI) and Electronic Potentiometer (E.P.).
P0121 – Speed Reference by the Keypad (HMI)
Adjustable Range:
0 to 10000 rpm
Factory Setting:
90 rpm
Properties:
Groups of
01 PARAMETER GROUPS
...
Access via HMI:
22 Speed References
...............
Description:
When the “
” and “
” keys are active (P0221 = 0 or P0222 = 0), this parameter sets the motor speed reference
value.
The value of P0121 will be maintained with the last value set even when the converter is disabled or powered
down, as long as parameter P0120 is configured as Active.
