Unit Description / Notes
Indicates the software version installed in the DSP memory located
x.yz
[ - ] on the control board.
Parameter P040, P203, P520 to P528 are only available from the
-
software version V3.50 on.
Indicates the value of the process variable used as PID feedback,
0...P528
in percent (%).
[ - ]
The PID function is only available from the software version V3.50
1
on.
The indication unit can be changed through P528.
See detailed description of the PID regulator in Section 6.3.5 -
Special Function Parameters.
This set of parameters defines the time to accelerate linearly from
0.1...999s
zero up to the rated frequency and to decelerate linearly from
[ 5.0s ]
the rated frequency down to zero.
0.1s (<100);
1s (>99.9) The rated frequency is defined by parameter:
- P145 in V/F control (P202=0 ou 1);
0.1...999s
- P403 in vector control (P202=2).
[ 10.0s ]
When factory setting is used, inverter always follows the time defined
0.1s (<100);
in P100 and P101.
1s (>99.9)
Ramp #2 is used, the the acceleration and deceleration times
0.1...999a
follow the values programmed at P102 and P103, use a digital input.
[ 5.0s ]
See parameters P263 ... P265.
0.1s (<100);
1s (>99.9) Depending on the load inertia, too short acceleration times can
disable the inverter due to overcurrent (E00).
0.1...999s
Depending on the load inertia, too short deceleration times can
[ 10.0s ]
0.1s (<100); disable the inverter due to overvoltage (E01). For more details,
refer to P151.
1s (>99.9)
0...2
The ramp S reduces mechanical stress during the acceleration and
[ 0 - Inactive ]
deceleration of the load.
-
It is recommended to use the S ramp with digital frequency/speed
references.
