Overview of the system variables
IPOS Variables
524 IPOS_Setp /
IPOS_SETP
IPOS setpoint, correcting variable of the PID controller when H540 = 1. When H540 = 0 or 2 the setpoint
can also be written directly from the user program.
H524 can be used as a torque setpoint or speed setpoint when P100 Setpoint source = IPOS and P700
Operating mode 1 = xxx&M-control, CFC or SERVO.
1 increment in H524 then corresponds to 0.21 rpm setpoint speed or 0.01% I

530 VarIntReq /
VARINTREQ
If the corresponding request bit of a variable interrupt is set, a variable interrupt is triggered irrespective of
the actual interrupt condition. The relevant variable interrupt must be activated beforehand.
Bit 0: Request for variable interrupt 0
Bit 1: Request for variable interrupt 1
Bit 2: Request for variable interrupt 2
Bit 3: Request for variable interrupt 3
540 PID_Mode /
PID.MODE
Operating mode of the PID controller, H540 and P260 are identical.
0 = Controller deactivated (default)
1 = Control active
2 = Step response (open control system)
541 PID_K_p /
PID.KP
PID-controller: Factor of the proportional component, H541 and P263 are identical, 3 decimal places; 0 <=
K
P
<= 32000 (= 32,000); default: 1000 (= 1,0)
542 PID_Outp_P /
PID.OUTPP
PID-controller: Current value of the controller's P-component
543 PID_Outp_I /
PID.OUTPI
PID-controller: Current value of the controller's I-component
The value for the l-component is in the high word, the internal components for decimal places are in the low
word, for example, H543 = 0x30000 -> l-component = 3.
544 PID_Outp_D /
PID.OUTPD
PID-controller: Current value of the controller's D-component
545 PID_Feedf /
PID.FEEDF
PID controller precontrol value; H545 and P266 are identical
-32000 <= Precontrol <= 32000; default: 0
546 PID_Command /
PIDCOMMAND
PID-controller: Setpoint, H546 and P271 are identical
When P270 = 0 (= "Parameter"), P271/H546 contains the required process setpoint
-32000 <= Setpoint <= 32000 (for speed control, 1 increment corresponds to 0.2/min); default: 0
547 PID_CmdAdr /
PID.CMDADR
PID-controller: Setpoint address, H547 and P272 are identical
When P270 = 1 (= "IPOS variable"), P272/H547 contains the address of the IPOS variable with the setpoint;
default: 0
548 PID_CmdScale /
PID.CMDSCA
PID controller: Factor for scaling the setpoint, H548 and P274 are identical, weighted with 3 decimal places
-32000 (-32,000) <= K
Setpoint
<= 32000 (32,000); default: 1000 (1,0)
549 PID_ActAdr /
PID.ACTADR
PID controller: Address of actual value, H549 and P276 are identical
When P275 = "IPOS variable", P276/H549 contains the address of the IPOS variable; default: 0
550 PID_ActScale /
PID.ACTSCA
PID-controller. Scaling factor of the filtered actual value, H550 and P277 are weighted identically with 3 dec-
imal places -32,000 <= K
Actual value
<= 32,000; default: 1000 (1,0)
551 PID_ActNorm /
PID.ACTNOR
PID controller: Filtered and scaled actual value, diagnostics value
552 PID_ActOffset /
PID.ACTOFF
PID controller: Integer, permanent offset of actual value, H552 and P278 are identical
-32000 (-32000) <= Offset <= 32000 (32000); default: 0
553 PID_ActMin /
PID.ACTMIN
PID controller: Minimum value for actual value after smoothing, scaling and offset, H553 and P280 are iden-
tical.
-32000 (-32000) <= x
e,min
<= 32000 (32000); Default: 0
554 PID_ActMax /
PID.ACTMAX
PID controller: Maximum value for actual value after smoothing, scaling and offset, H554 and P281 are iden-
tical.
-32000 (-32000) <= x
e,max
<= 32000 (32000); default: 10000 (10,0)
555 PID_LimitMin /
PID.LMTMIN
PID controller: Minimum output value, H555 and P282 are identical
-32000 (-32000) <= x
controller,min
<= 32000 (32000); default: -1000 (-1,0)
556 PID_Limit_Max /
PID.LMTMAX
PID controller: Maximum output value, H556 und P283 are identical
-32000 (-32000) <= x
controller,max
<= 32000 (32000); default: 10000 (1,0)
