Code Name/Description Setting range Factory settings
PID controller specified speed input
nO [No] (nO) : Not assigned (function not active)
AI1 [AI1] (AI1) : Analog input
AI2 [AI2] (AI2) : Analog input
LCC [HMI] (LCC) : Graphics terminal
Mdb [Modbus] (Mdb) : Not applicable
CAn [CANopen] (CAn) : Integrated communication interface (POWERLINK)
nEt
[Com. Card]
(nEt) : Communication card (if present)
PG [Encoder] (PG) : Encoder input if encoder card has been inserted
PSr
[Speed input %]
1)
1 to 100% 100%
Multiplying coefficient for predictive speed input.
The parameter is accessible when [assign ref of PID] (PES) = [No] (nO) .
PAU [Auto/Manual assign] [No] (nO)
nO [No] (nO) : The PID is always active.
LI1 [LI1] (LI1)
- .
[...] (...) : See the assignment conditions
In state 0 of the input or the assigned bit, the PID controller is active.
In state 1 of the input or the assigned bit, the manual operation is active.
AC2 [Acceleration 2]
1)
0.01 to 6000 s
3)
5 s
Time till acceleration from 0 to [Rated motor frequency] (FrS) . Make sure that this value is compatible with the frequency inverter's moment
of inertia.
Ramp AC2 is only active when the PID function starts up and during PID wake-ups.
PIM [Manual reference] [No] (nO)
Manual speed input. This parameter can be activated if [assign. auto/manual] (PAU) is not equal to [No] (nO) .
nO [No] (nO) : Not assigned (function not active)
AI1 [AI1] (AI1) : Analog input
AI2
[AI2]
(AI2) : Analog input
PG [Encoder] (PG) : Encoder input, if encoder card present
The preset speeds are active on the manual reference if they have been configured.
tLS [Low speed time out]
1)
0 to 999.9 s 0 s
Maximum operating time with [low speed] (LSP) .
Following operation at LSP for a defined period, a motor stop is requested automatically.
The motor restarts when the reference is greater than LSP and if a run command is still present.
Caution!
A value of 0 indicates an unlimited period of time.
Note:
If [operating hours for LSP] (tLS) is not equal to 0, the parameter [STOP MODE] (Stt) ( see "STOP MODE (Stt-)" on page 206 ) is
forced to [stop ramp] (rMP) (only if stop can be configured via ramp).
rSL [PID wake up thresh.] 0 to 100 0
If the functions "PID" and "Duration of operation at low speed" (tLS) are configured at the same time, the PID controller may attempt to set a
lower speed than LSP .
This results in unsatisfactory operation, which consists of starting, operating at LSP then stopping, and so on…
With the parameter rSL (threshold value of the deviation at restart), a minimum threshold of the PID deviation can be set for the restart after a
standstill in the event of lengthy operation with low speed LSP .
The function is inactive if tLS = 0 or if rSL = 0.
Warning!
ACCIDENTAL OPERATION OF DEVICE
Check that an unexpected restart will not present any danger.
Failure to follow these instructions will result in death or serious injury.
1) This parameter can also be accessed via the
[SETTINGS]
(SEt-) menu.
2) If there is no graphic display terminal, then on the four-digit display the values over 9999 are shown with one point after the thousands unit, for example,
15.65 for 15650.
3) Range 0.01 to 99.99 s or 0.1 to 999.9 s or 1 to 9999 s in accordance with
[ramp increment]
(Inr) .
Parameter that can be modified during operation or when stopped.
