(CPOS)

ILC002

-2

31

to 2

31

-1

This parameter indicates the calculated position in a machine
coordinate system controlled by MP940 Modules. Normally
the position data indicated at this register is the target posi-
tion for each scan.
Refer to Supplemental Explanation.

5

Target Position
Difference Monitor
(PTGDIF)

ILC004

-2

31

to 2

31

-1

This parameter indicates the amount cleared every scan.

31

to 2

31

-1

This parameter indicates the current position the instant the
DI latch signal turned ON.
Refer to Supplemental Explanation.

ILC008

-2

31

to 2

31

-1

This parameter indicates the current monitor position.

Note: It is not valid when an A Drawing is executed.

It is valid when an H or L Drawing is executed.

Refer to Supplemental Explanation.

11

Position Error
(PERR)

ILC00A

-2

31

to 2

31

-1

This parameter indicates the position error (number of pulses
held).
(Position error = target position - current position for each
scan). It is valid in Zero Point Return Mode, Position Con-
trol Mode, and Phase Control Mode.

13

Speed Reference
Output Monitor
(SPDREF)

IWC00C

-32768 to 32767

This parameter indicates the value output at the servo drive
as the speed reference output value.

14

Speed Monitor (NFB) IWC00D

-32768 to 32767

Reports SGDH parameter Un000: Actual Motor Rotation
Speed (r/min.) as %/number of rated rotations.
1=1%

15

Torque Monitor (TFB) IWC00E

-32768 to 32767

Reports the value of SGDH parameter: Un002 Internal
Torque Reference (%).
1=0.01%

16

Out of Range
Parameter Number
(ERNO)

IWC00F

1. Motion setting

parameter
1 to 65

2. Motion fixed

parameter
101 to 148

This parameter indicates the most recent setting parameter
number that exceeded the range in OWC000 to OWC03F
motion setting parameter or motion fixed parameter settings.

• Motion setting parameters: 1 to 65
• Motion fixed parameters: 101 to 148

When motion fixed parameters are used, the parameter indi-
cates the parameter number plus 100.
