Overview of the system variables
IPOS Variables
499 SetpPosBus /
SP.POS.BUS
Setpoint position bus, READ.
Contains the setpoint position which is sent via the fieldbus process data. The setpoint position is only
accepted if "POSITION LO" and "POSITION HI" are programmed in the PO-data description (parameter
group P87_).
500 TpPos2_VE /
TP.POS2VE
Only used in MOVIDRIVE
®
B; reserved in MOVIDRIVE
®
A.
The value of the virtual encoder H376 is stored in H599 if input DI03 has been activated (see also
_TouchProbe()/TOUCHP).
501 TpPos1_VE /
TP.POS1VE
Only used in MOVIDRIVE
®
B; reserved in MOVIDRIVE
®
A.
The value of the virtual encoder H376 is stored in H501 if input DI02 has been activated (see also
_TouchProbe()/TOUCHP).
502 TpPos2_Abs /
TP.POS2ABS
The touch probe positions are stored in the following variables:
Encoder Encoder position Touch probe 1 Touch probe 2
DI02 DI03
Motor encoder (X15) H511 ACTPOS.MOT H507 TP.POS1MOT H505 TP.POS2MOT
External encoder (X14) H510 ACTPOS.EXT H506 TP.POS1EXT H504 TP.POS2EXT
Absolute encoder (X62) H509 ACTPOS.ABS H503 TP.POS1ABS H502 TP.POS2ABS
503 TpPos1_Abs /
TP.POS1ABS
504 TpPos2_Ext /
TP.POS2EXT
505 TpPos2_Mot /
TP.POS2MOT
506 TpPos1_Ext /
TP.POS1EXT
507 TpPos1_Mot /
TP.POS1MOT
508 IPOS counter • Counter value for the frequency input (if it is activated via DIP switch S14)
• High-resolution motor position (if the interpolated position signal is set via P916)
509 ActPos_Abs /
ACTPOS ABS
Current actual position of the DIP absolute encoder (SSI), READ.
IMPORTANT: System control variable Value must not be overwritten.
This actual position is determined via the signals which are active on plug connector X62 (DIP11A
option).
Unit: Increments depending on the encoder resolution.
510 ActPos_Ext /
ACTPOS EXT
READ current actual position external encoder.
IMPORTANT: System control variable Value must not be overwritten.
The actual position is determined via the track signals which are active on plug connector X14.
Position detection is only performed if connector X14 is used as the encoder input.
Unit: Increments depending on the encoder resolution.
511 ActPos_Mot /
ACTPOS.MOT
READ current actual position motor encoder.
IMPORTANT: System control variable Value must not be overwritten.
The actual position always has the following unit, regardless of the encoder pulse count per revo-
lution: 4096 increments per motor revolution (encoder resolution 512 inc., exception: MQx with
NV26 has 24 Increments per motor revolution).
